this is bbc news with the latest headlines: the home secretary, priti patel, says she is looking at a "whole spectrum" of measures to better protect mps following the death of sir david amess. i think it's fair to say we all have to be incredibly self—aware, conscientious, as to how we conduct our business and put safety front and centre of this. issues on social media have been highlighted as part of the discussion around the safety of mps the social media companies could do a lot more. they could take down some of these accounts. and they could end what you might call end—to—end anonymity.

the man arrested by police following the killing of the uk mp sir david has been named as ali harbi ali and is being held under the terrorism act. officers have until friday to question him. a princely prize — the duke of cambridge prepares to reveal the winners of a new environmental award. some of the busiest rail routes between london and the south—east of england are being taken over by the government today and coming up in half an hour — david sillito reports on the shortlisted buildings — including winner of the 2021 riba stirling prize — one of the most prestigious awards in architecture. good afternoon. the home secretary, priti patel, says mps may be offered police protection at constituency surgeries following the killing

of sir david amess. a security review is already happening. it will consider whether these meetings should only take place with a pre—booked appointment. the man arrested by police following the killing of the mp, sir david amess, has been named as ali harbi ali. the 25—year—old is being held under the terrorism act and officers have until friday to question him. our political correspondent peter saul reports. this tight—knit seaside community continues to mourn its member of parliament, stabbed to death while meeting the people he was selected to represent. the tragedy has really hit home for mps, many of whom considered sir david amess a friend, and some are reassessing the way they work. none of us are afraid to walk out of our doors and to attend local events and do surgeries, and meet people, but now there's obviously a fear that there's bad people out there that want to do harm, and david is a victim of that. and so i'm afraid it

will change things. do you feel safe doing yourjob, going around your constituency? no, not really, if i'm honest. i feel quite fortunate to have a lot| of constituents who are concerned about my safety, wigan is that sort of place. - people look after each other. security was tightened in mps's offices following the murder ofjo cox in 2016 and many believe action is needed now. i do think there is more to be done by parliament working with the venues where we hold our advice sessions with local authorities, otherwise to make us feel physically safe. such is the screening for covid. the home secretary said her world was shattered when she heard about sir david's death and is now considering a range of measures to protect her colleagues.

we are doing a lot of practical things right now in terms of advice for mps. but i think it's fair to say we all have to be incredibly self—aware, conscientious as to how we conduct our business. she herself has been subject to online abuse, and also spoke of proportionate action against anonymous social media accounts. speaker: order! part of the common speaker so lindsay hoyle's role is to ensure mps are safe and he has acknowledged the need for improvements. but in a newspaper article he stressed the importance of constituency surgeries, describing them as a cornerstone of our democracy. he also said that the political conversation had to be kinder and based on respect. in recent days party politics have been put to one side, and in a further sign of respect labour and the liberal democrats will not contest the by—election that will now need to take place here. peter saull, bbc news. our home affairs correspondent daniel sandford has more details about the suspect and the investigation. while a lot of work is still going on in

leigh—on—sea, part of the focus of the investigation has very much moved to london. we have been watching today as officers have prepared to search a house in the kentish town area of north london that is believed to being connected to this investigation. counterterrorism detectives are trying to find out more about the suspect ali harbi ali. his father is involved in somali politics and spends most of his time either in kenya or the bounds green area of north london. ali harbi ali was detained at the scene of the attack and is now being held at a london police station. he can be held up until friday because he is now being held under the terrorism act before he is charged or released. it is worth saying at this stage he is still a suspect and has not been charged. priti patel said the government's online harms bill offered an opportunity for all mps to come together to close "the corrosive space online". the conservative mp damian collins is chair of thejoint committee on the online safety bill and joins us now.

good and joins us now. to have you with us. and ijust wondered good to have you with us. and ijust wondered for a i can get your perspective on what you think can be done to better protect mps and shield them from some of the hostility they come across presumably day—to—day in the work they do. presumably day-to-day in the work the do. ., ., ., , they do. the online environment has become a hostile _ they do. the online environment has become a hostile environment - they do. the online environment has become a hostile environment is - they do. the online environment has become a hostile environment is noti become a hostile environment is not just for members of parliament that we can't accept that death threats to members of parliament and threats of physical violence abuse to just be seen as part of the modern world is that it is online there is nothing anybody can do about it. just in the same way that racist abuse and others on a daily basis and the awful misogyny directed at women we've got to at this and say i think there is a sickness in this, and the way social media is used and it spills out to society and at times leads to violent acts being committed and i think we have to do something about that in the online safety bill is looking at how we address the spread of this file

content, this content which can lead to very severe real—world consequences so i think that something with the online safety bill in the work we're doing on the joint committee that we have to do. what is sickening about this brutal murder of my colleague david amess is not that we've lost a great man but it was done in a way to strike at the heart of how democracy works. that precious linkedin members of parliament and their constituents and there are things we can do to keep myself save and mitigate those risks but ultimately i think we all want to carry on meeting directly with constituents and that's all we can do is try to manage that risk. have you ever had any situations during your constituency surgeries we felt unsafe, threatened or even had have someone remove from them because things were getting uncomfortable?— because things were getting uncomfortable? . ., �* ., uncomfortable? nave. i haven't had that but i uncomfortable? nave. i haven't had that but | think— uncomfortable? nave. i haven't had that but | think what _ uncomfortable? nave. i haven't had that but i think what is _ uncomfortable? nave. i haven't had that but i think what is interesting l that but i think what is interesting is as we understand more about this case and what happened to david is we were advised that the police that

if there is a problem it is someone who has a track record of making threats before and that escalates. i think what would be very concerning in this case would be if that was not the case and he had no dealings before. that sort of thing can be much harder to track.— much harder to track. you're chairin: much harder to track. you're chairing the _ much harder to track. you're chairing the committee - much harder to track. you're chairing the committee on i much harder to track. you're - chairing the committee on online harms bill. what are the one are two key points that you would like to see consensus be reached onto deal with some of the problems that you've outlined? we with some of the problems that you've outlined?— with some of the problems that ou've outlined? ~ , ., _, , you've outlined? we should recognise that someone — you've outlined? we should recognise that someone receiving _ you've outlined? we should recognise that someone receiving death - you've outlined? we should recognise that someone receiving death threats| that someone receiving death threats on social media that could lead to violence being committed against them as a credible risk of harm and should not be allowed and the job of the regulator should be to work with companies to say these are the sorts of areas of content we expect you to remove and do a check that you're doing it properly so that is something from a regulatory point of view. gives us the power we've never

had before which is really to work with companies and making sure they do do it. there is a separate question which the home secretary is touched on today which is about anonymity. if a social media company does allow someone to use a false name that companies should hold an update information about that individual so that the police can get access to that with a court order as part of an investigation and users should know that even if they are not using their real name when they pose they can and will be identified if they create and cause harm to other people and i think that would have a mitigating effect on some of this abuse. these anonymity to do things they would not say in the real world. so these are two areas that the bill really needs to look at very hard on a job as a committee is to make recommendations to the government in december on behalf of parliament on

how and where we think the bill could be strengthened. the difficulties _ could be strengthened. the difficulties greasing that, isn't it? because he was down two to enforce some of those measures you suggest because social media companies are headquartered outside the uk, it is how to force them to do things. the police start taking it on there will be people who criticise them for doing that and saying they should be dealing with, you know, actual violent crime having their you know, actualviolent crime having thei— you know, actualviolent crime havinathei , , ., ., ., having their this is for parliament and the government _ having their this is for parliament and the government to _ having their this is for parliament and the government to decide - having their this is for parliament - and the government to decide through legislation what we think the responsibilities of the companies are. and checking and auditing the companies to make sure they are fulfilling their obligations and that regulator would have the power of massive sanctions on sat fines against the company then we should consider whether they could be regarded as negligent and open to civil prosecution cases like this. they have to buy by the local laws with a trade. in germany there are very specific laws on hate speech particularly related to anti—semitism and the glorification

of nazi ideology. and enforced online in germany and they have to be content for anyone who can be seen within anyone in germany. companies have to comply with the laws and the countries where they do business. i laws and the countries where they do business. . , , . ., , , business. i appreciate this is legislation — business. i appreciate this is legislation that _ business. i appreciate this is legislation that rbc - business. i appreciate this is legislation that rbc takes i business. i appreciate this is i legislation that rbc takes time business. i appreciate this is - legislation that rbc takes time to work through but in the meantime, personally, how do you respond? how do you deal with online hostility or threats that may come your way through the nature of your work? how do you handle that? you through the nature of your work? how do you handle that?— do you handle that? you can stop it. some account _ do you handle that? you can stop it. some account to _ do you handle that? you can stop it. some account to be _ do you handle that? you can stop it. some account to be violent - do you handle that? you can stop it. some account to be violent or- some account to be violent or abusive or during a public space online as well and other people can, and do it. the members of parliament particularly women face terrible abuse all of the time. as i said earlier on as do other people in the public eye including sports stars and other personalities as well. i don't think we should have to accept it. tech companies could do more to put this right. they know

legislation is coming and they have to look at the way the environment they have created, the public square they have created, the public square they have created is lighter and increasingly full of violence and they could do that now. fears on theseissues they could do that now. fears on these issues in the last few years has been that self—regulation to fail. they won't act unless they are required to act as i think it is time for parliament and the government to say what we expect them to do. is government to say what we expect them to do— them to do. is some of the owners aren't the people _ them to do. is some of the owners aren't the people who _ them to do. is some of the owners aren't the people who set - them to do. is some of the owners aren't the people who set the - them to do. is some of the owners aren't the people who set the tone of conversation in the public sphere, be that politicians, commentators and others to adjust ratchet down the intensity and hostility around some conversations are got so far beyond that that would make no difference? the sort of content we _ would make no difference? the sort of content we had _ would make no difference? the sort of content we had talking _ would make no difference? the sort of content we had talking about - would make no difference? the sort of content we had talking about is i of content we had talking about is not coming through this, it has been developed in groups and channels on these platforms and people are being exposed to more radical content and we know that the system is that the

companies have created tend to radicalise opinion in order to hold engagement. if they see someone is engaging with extremist content to give more engagement. there is one study showing that on facebook the platform actively recommended joining a group to extremist content. we have to deal with the design of the systems which is increasing divisions in society and driving people to more extreme content in the systems have been designed to hold engagement to make money. if we could effectively control the way in which, the extent to which this abuse spreads to the internet we have been a stronger position. when there is file these after their football final not only was this shared and promoted on social media platforms but the recommendations were making people aware of it and spreading it so these are all sorts of things that these are all sorts of things that the safety regulator would be able

to take into account. how we regulate business decisions. thank ou ve regulate business decisions. thank you very much _ regulate business decisions. thank you very much indeed. _ regulate business decisions. thank you very much indeed. thank- regulate business decisions. thank you very much indeed. thank you. | thank you. joining me now is the speaker of the house of commons, sir lindsay hoyle... what you think either one or two things that need to be considered seriously in order to improve the safety of mps and their staff and families? �* , ., ~ , families? i've been taking this seriously for _ families? i've been taking this seriously for many _ families? i've been taking this seriously for many years - families? i've been taking this seriously for many years and l families? i've been taking this i seriously for many years and that had been part of my duties and when the speaker asked me to chair the panel on the security for the house of commons and also the house of commons and what i would say is that we regularly update security and we look at security. we put other measures in place that we feel are the best measures to support mps to

work and also to protect their families as well as the staff so what i would say is i don't want to go into a kneejerk reaction what i would say is i don't want to go into a knee jerk reaction to say what we need to do. tragically we have lost our friend david amess and our thoughts are with his family and what i want to say is we've got to do the right thing. we've got to make the best come out of this hideous hideous killing of a colleague and we will look at all different measures. we will review measures. we will also remind members please take up the measures that are available to you. those measures are there to protect you, your stuff and your family. and that is what we have got to do. you got to know what happened on friday, the tragedy of what happened, the got to learn from that. you got to find out the measures have worked and not worked? we got to make sure we're getting it right. of course everybody will be expressing different views and opinions on what

we need to do and what i would say we've got to protect democracy. the got to protect members. because the people hate our values and what we stand for and they hate the democratic process and that's the thing that we are fighting so we cannot give in and must not giving and it was the right thing when i did my surgery on friday night my constituents needed access to me. they gave them that access. and quite rightly but we've also got to do is make sure they are protected as well when they come to be a member of parliament so of course we've got to learn from this. we have got to sure. it is a sad time. people quite rightly are very worried it is about the reassuring that we need and thinking about david's family as well at this moment. a, david's family as well at this moment-— david's family as well at this moment. �* ., ., , , david's family as well at this moment. �* ., , ., moment. a lot has been said about the nature public— moment. a lot has been said about the nature public discourse - moment. a lot has been said about the nature public discourse and - the nature public discourse and conversation in the online sphere. i've seen many times as will our viewers you during debates in the

house rainy mps and when you feel they have crossed a line things got beyond what is acceptable. it is one thing to have that ability within the chamber. how giving that same standard and limit when it goes beyond the chamber? what standard and limit when it goes beyond the chamber? what we've got to do is protect _ beyond the chamber? what we've got to do is protect mps _ beyond the chamber? what we've got to do is protect mps beyond - beyond the chamber? what we've got to do is protect mps beyond that - beyond the chamber? what we've got to do is protect mps beyond that and| to do is protect mps beyond that and talking about social media. our challenge is to work with social media companies and we do review what has been said against mps. mps can sign up and it is not what the mps are saying that what is being said about the mps so we can immediately intervene and if it is very serious it is referred to the and of course we can warn members unless there companies to take it down. we take social media very seriously. it inflames and drives others to do things that we quite

rightly do not fit in with their values and thoughts and i'm going to say we've got to learn from capitol hill. social media was used to whip up hill. social media was used to whip up a mob to attack capitol hill on part of the speakers conference was about an open and secure parliament. making sure we get that right was at the balance between open parliament and open democracy compared to a close democracy. so that conference was to debate social media, the impact on social media. what that does but what i would say is that some are a lot better than others and what you got to do is make sure we are challenging them and when they've asked for them to be taken down they responded and as you say, it is difficult when some of the things i put in offshore. it is the offshore accounts that are difficult to deal with. we had an incident not too long ago where there were

addresses of senior politicians. the companies did work with us because that was leaving them very vulnerable and open to threat so i take this role very seriously. take security very seriously and we've got very good people who work on behalf of us to make sure we are secure. i can't thank them enough for thejob that secure. i can't thank them enough for the job that they do. they are working 2a hours a day to try and help protect us. i working 24 hours a day to try and help protect us— help protect us. i was in leigh-on-sea _ help protect us. i was in leigh-on-sea yesterday help protect us. i was in - leigh-on-sea yesterday and so help protect us. i was in _ leigh-on-sea yesterday and so the leigh—on—sea yesterday and so the flowers and messages by way of tribute to the memory of sir david. there have been vigils held in church services. ijust there have been vigils held in church services. i just wonder when parliament returns what friends are there or ideas for marking his memory and honouring the contribution is made to public life and politics. contribution is made to public life and politics-— and politics. you're absolutely ri . ht. and politics. you're absolutely riuht. he and politics. you're absolutely right- he was _ and politics. you're absolutely right. he was a _ and politics. you're absolutely right. he was a great - and politics. you're absolutely. right. he was a great politician. and politics. you're absolutely i right. he was a great politician. a politician who enjoyed his job, he got the best out of the job and

that's why he was so well loved within his constituency and across the house. we will be paying tributes to david and will start off with questions and will go into tributes and that will continue then will have a service following the tributes. and of course what we've got to do, how can we remember sir david? as a friend, is a colleague, as a member of parliament will i think no better tribute would be ensuring that his constituency gets the city status. he requested it. he wanted it and he wanted that to happen. he was always at the forefront of mentioning southend and mentioning that status. that would be a good thing to do. it would be a nice thing to do in herjubilee for her majesty. be having discussions with the family. when jo

her majesty. be having discussions with the family. whenjo cox was murdered on the streets of a constituency received a plaque, edge coat of arms to joe constituency received a plaque, edge coat of arms tojoe cox. wouldn't it be nice to do the same for david but thatis be nice to do the same for david but that is a family discussion we need to have but memories like that. they'll be there forever for others to remember what a great colleague are great colleagues we have lost as we look around the chamber at the different mps have been murdered. thank you. the duke of cambridge will call for society to "unite in repairing our planet", when he appears on stage tonight at the first awards ceremony for his environmental prize. the earthshot prize will celebrate five winners who've come up with the best solutions to tackle the world's environmental problems. james reynolds reports. each year, we will award five £1 million prizes to those who we believe can transform our chances

of repairing our planet. prince william's earthshot winners will be announced tonight. the prize takes its inspiration from president kennedy's 1960s moonshot, the desire to unite around a single scientific project. ultimately if we want to tackle this, if we want to get on the front foot, we've got to bring people with us. people have got to feel like there's hope, there's a chance we can fix this. and that's what the earthshot prize is about is providing those solutions to some of the world's biggest environmental problems. the project has won praise from his own father. "we need to come together to build the sustainable future we so desperately need," tweets the prince of wales. a less wild world is a less stable world. prince william has also teamed up with david attenborough, who has himself spent many years warning of the dangers posed by climate change. that's why i agreed to join the earthshot prize council. i noticed the ironing vendors in my street using charcoal. | the earthshot finalists include

14—year—old vinisha umashankar from tamil nadu in southern india. she's designed a solar—powered ironing stall. it even has a mobile phone charging point. and earlier this week, buckingham palace and other london landmarks were lit up in green to mark this evening's earthshot awards. james reynolds, bbc news. the government has taken over the running of the southeastern rail network —— which connects kent and some of east sussex with london. the move was announced last month after govia, which had been running the franchise, failed to declare more than 25 million pounds of taxpayerfunding. passengers have been told they are unlikely to see any immediate changes to services. windermere in the lake district could become ecologically dead within years, because of the amount of sewage

being pumped into its waters, according to campaigners. an online petition calling for a ban on sewage pollution, has now reached over 99—thousand signatures. but, the situation is complex, as our environment correspondent judy hobson explains. tourists come to the lake district for its outstanding natural beauty, but campaigners say the water quality in windermere is so poor, it is a national scandal. there has just been the biggest blue—green algal bloom, all because of sewage entering the lake. a local conservationist has been filming water pollution in the area. that dark patch is an algal bloom. this is the river rothay that feeds into the lake. it actually prevents invertebrates from being able to breed on the substrate of the river itself and then, because of that, invertebrates have died and, subsequent to that, fish are dying. matt has started an online petition calling for a ban on sewage pollution in windermere. he said the waters here are close to ecological collapse.

i have seen a decline in fish, invertebrates, freshwater vegetation. i have seen otter spraint completely absent of white—clawed crayfish. i have seen dead fish floating down the river past me. it is in a dire state and it will only get worse. algal blooms come and go, but they are appearing more frequently and they can be very harmful to humans and animals. there are two many main sources of sewage entering windermere. one is at the waste treatment site. that comes in when we have rain. they call it their storm overflow. a system. and the other is from septic tanks. there are over 1500 septic tanks that are around windermere itself and there is no regulation keeping these in check. last year, the sewage treatment plant at ambleside overflowed for weeks after heavy rain. what you can see is the fine filters at the back end. the company said it happens to prevent flooding, but a new plant at windermere is now improving water quality. over the past five years we have invested £40 million into assets around windermere both at ambleside,

glebe road station and here at windermere waste water treatment works to address some of those challenges. but the sewage problem comes from different sources and the answer will be four different organisations to work together. the nutrients have probably been discharged over decades. it is a case of continual improvements and ongoing work and then looking to the future. it is notjust local people, it is a special part of the world for millions from all around the world. it is a unesco world heritage site. it is known for its natural beauty and now we have to protect that. that was judy hobson reporting from the lake district. the weather is pretty cloudy across most of the uk right now. mild but it is only going to get milder. for the course of this week temperatures up the course of this week temperatures up to 21 . here is the summary. rain

at times and strong winds to come through the course of the week was that this is what the satellite picture looks like right now. they are definite south and south—west so we've had some sunshine so far. cornwall, devon, much of the west country and into the midlands very pleasant afternoon here but further north it is cloudy and despite cloud and bits and pieces of rain that we've got right now empties will still get up to 16. here is the night and you can see a lot of cloud across the northern half of the uk. in the south will be clear spells. the temperatures and elsewhere do will be a very mild night. i had started tomorrow as well. we've got another weather front approaching and a lot of cloud out towards the west approaching as an reigning across western areas. the less pay to see the rain tomorrow late in the day will be norwich and here even evidence and turnaround. i7

day will be norwich and here even evidence and turnaround. 17 in belfast and that is despite the cloud and rain and the cloud and the rain will continue to tomorrow evening with the main parties in a little bit but a lot of cloud around. the reason is low pressure. no pressure is over as but what is unusual, not unheard—of is this plume of warm air coming in from the is yours which will temporarily bump up is yours which will temporarily bump up the temperatures to 20 or 21 on tuesday despite all of this. these are warm south—westerly is spreading right across the country so they get that in scotland and in the lowlands. tuesday into wednesday low pressure is over us. blobs are rain dotted around across the country so a very changeable week. spurs of

wind. confide it looks as though things are going to come down and brighten up at least for the time being. into the following weekend it is back to square one. hello, this is bbc news. the headlines... the home secretary, priti patel, says she is looking at a "whole spectrum" of measures to better protect mps following the death of sir david amess. i think it's fair to say we all have to be incredibly self—aware, conscientious as to how we conduct our business and put safety front and centre of this. issues on social media have been highlighted as part of the discussion around the safety of mps. we ta ke we take social media very, very serious. in flames it inspires and helps others do things we quite

rightly do not fit in with our values and thoughts. 0vernight police presence at a house in north london, thought to be related to the stabbing of sir david amess. a princely prize — the duke of cambridge prepares to reveal the winners of a new environmental award. some of the busiest rail routes between london and the south—east of england are being taken over by the government today. now on bbc news, david sillito is on the hunt for britain's best new building — and winner of the 2021 stirling prize for architecture. and winner of the 2021
