the home secretary amber rudd has announced the terror threat in the uk has been lowered from critical to severe. that means an attack is highly likely, rather than imminent. the decision has been taken after detectives made a second arrest in their investigation into the friday london tube bombing. the 21—year—old man was detained at hounslow in west london late last night. detectives are continuing to question a teenager who was arrested in dover in kent. 30 people were injured when the device detonated at parsons green station. we can listen to amber rudd, home secretary now. following the attack in parsons green last friday, the police have made good progress in what is an ongoing operation. the joint terrorism analysis centre, reviewing the threat level the uk is under, have decided to lower that level from critical to severe.

severe still means an attack is highly likely, so i would urge everybody to continue to be vigilant, but not alarmed. as the prime minister said last friday, the military were called to support the police, so armed police officers would have a greater presence on our transport network and our streets. during the next few days the military will return to their original positions, and i would like to ta ke original positions, and i would like to take this opportunity to thank them for their hard work. and also them for their hard work. and also the police, security services and emergency services, who did such a fantastic job combating what emergency services, who did such a fantasticjob combating what was done at parsons green on friday. that was home secretary, amber rudd. jane frances kelly reports. as investigations enter their third day, following the terror attack at parsons green, police say they have arrested a second man, who is 21. he was detained late on saturday night in hounslow in west london, and is now being questioned. it follows the arrest of an 18—year—old man early yesterday

morning at the port of dover, which had to be partially evacuated. the home secretary said the police and security services are still trying to establish just how many people were involved in the attack. this has been a year like no other. we have seen five serious attacks and six that were foiled by the police, and the police are getting on with doing their operation today. they are working closely with the security services. there is still intense police activity at the terraced house in sunbury where the 18—year—old is believed to have lived with an elderly couple, known for fostering hundreds of children, including refugees. penny and ronjones were recognised for their services by the queen when they were made mbes in 2010. their house is just over 11 miles away from the attack. it appears that the improvised explosive device at parsons green station, which was placed in a bucket, produced a sheet of flames, but failed to go off properly. had it done so, hundreds of people packed into the train could have

been killed or seriously injured. several victims were treated in hospital but none suffered life—threatening injuries. armed officers are patrolling stations and busy venues, while the investigation seeks to establish just who was behind friday's attack and whether more are planned in the coming days. jane frances kelly, bbc news. ina in a moment we will go to sunbury—on—thames. but first to anisa kadri, who is at new scotland yard. the home secretary saying the terror threat level has been reduced, suggesting police think they have made progress in their investigation. the home secretary has said the police have made good progress. all along what we have heard from the met is that they are keeping an open mind on how many suspects are involved, but the

investigation is fast—moving. there have now been two arrests. 0ne investigation is fast—moving. there have now been two arrests. one of them late last night. that was the second arrest, in hounslow. a 21—year—old man arrested in hounslow. we understand that a residential property at stand well is being searched in connection with that arrest. earlier an 18—year—old was arrested in dover and an investigation in sunbury—on—thames has been the focus of the investigation so far. the terror that has been reduced from critical to severe, an attack is still highly likely, but we will see fewer armed forces on the streets as you do when the terror threat is critical. we can go now to sunbury—on—thames where there has been quite a bit of police activity. that's right, and

it remains the case here on cavendish road in sunbury—on—thames. you can see behind me, this is the inner police cordon we are standing at, a semipermanent cordon that has been put in place. we know they are working on a property inside that cordon and have been since yesterday afternoon at around 2pm. a forensic tent has been placed in the front garden. also in the back garden you can see a conservatory in the back garden where a forensic tent has been placed to the back of a conservatory. another tent where forensics have been working on, bringing goods out of the house and working on them in the privacy of the tent. residents saying they have seen the tent. residents saying they have seen things being brought out of the house. local residents also saying they have seen dogs of the titan breed that looked like sniffer dogs in this area. that house is where the 18—year—old arrested yesterday in dover is believed to have been

living recently with the couple run and pennyjones. 71 and 88 years old. long—term foster carers over a0 yea rs, old. long—term foster carers over a0 years, receiving mbes for their work in foster care. they have looked after eight refugees in recent years and people say recently there has been an 18—year—old and 22—year—old living with them, both of whom are refugees. some residents suggesting there has been some police activity in and around the property in recent weeks. nothing to suggest that is anything to do with this at the moment. this operation here now has been going on for more than 2a hours. we have heard this afternoon that following a second arrest of a 21—year—old man in hounslow last night, now a search is taking place ata night, now a search is taking place at a residential address in stanwell in surrey in connection with this

incident. that around four miles from. it certainly doesn't look like the is easing up. thank you for the update from sunbury—on—thames. the home secretary, amber rudd, has accused borisjohnson of "backseat driving", by writing a newspaper article setting out his vision for brexit just days before theresa may is due to deliver a major speech on the subject. mrjohnson's spokesman insisted the foreign secretary was fully behind the prime minister's plans for brexit. 0ur political correspondent chris mason reports. not since here injanuary has the prime minister given a big set—piece speech on brexit. but on friday she will, in florence. that's why borisjohnson's intervention matters, notjust because of his own ambitions, but because it highlights the rows within government about the flavour of brexit the country signs up to. i don't want him managing the brexit process. what we've got is theresa may managing that process. she's driving the car, to continue the allegory, and i'm going to make sure that,

as far as i'm concerned and the rest of the cabinet are concerned, we help her do that. this is a difficult moment. so this is back—seat driving? yes, you could call it back—seat driving, absolutely. boris johnson, seen here campaigning earlier this year, said in his article that the uk had a glorious future and should not pay for access to european markets after brexit. he also offered views on the education system, funding for the health service and tax. it's led political opponents to say he should be sacked. it's a terrible situation, and it puts theresa may in an impossible position. ijust don't understand why she hasn't fired him. it's like a school that is completely out of control, and the headteacher‘s sitting in her office paralysed and impotent. the prime minister's deputy agreed with the home secretary that mrjohnson's timing could have been better, given friday's terrorist attack, but when asked if he's going to lose hisjob, said... no, he isn't, and the reason is that he, like the rest of the cabinet, like the prime minister,

is all about wanting to get the best dealfor the british people. and that is a long and difficult process that will take us the next 18 months or so. is it not time we took back control? the foreign secretary's spokesman said the prime minister is leading the brexit negotiations, and borisjohnson is fully behind her in getting the best deal. chris mason, bbc news. with me isjohn rentoul, chief political commentator at the independent. as we know borisjohnson steps out ofa carand as we know borisjohnson steps out of a car and people ask what he means by that movement. this article is pretty incredible, laying out his positive vision for brexit. and it reads like his conference speech. i think he drafted it as his conference speech and then realised that theresa may is going to make an important speech in florence this

week, on friday. he wanted to influence her position in that speech, was annoyed that i think they held the cabinet committee without him while he was in anguilla dealing with a hurricane. he wanted to make a speech but wasn't allowed to make a speech but wasn't allowed to buy number ten and decided to publish it in the telegraph anyway. he sounds frustrated. the fact he has raised yet again the £350 million emblazoned on the side of the leave bus that many of us spent many weeks travelling around on during the referendum. he got into trouble over that statistic and he is against the other he is again! it was a very foolish move to mention that number again. he didn't need to do that. it's pure red rag to the remainer balls. everybody knows it isn't true. he has been told off by the head of the statistics authority this afternoon. best the remainer bulls. he could have just made the point

that he's in favour of more spending on the nhs, which everybody agrees with, and he would be cheered to the rafters for, but instead he has to spoil it. he's a straight because he has to put forward this positive side of brexit. he's clearly concerned, as side of brexit. he's clearly concerned , as are side of brexit. he's clearly concerned, as are other so—called brexiteers, that britain could end up brexiteers, that britain could end up the worst of all worlds, not com pletely up the worst of all worlds, not completely out and still pay money in. the advantages he sees of leaving will not be there. it's interesting that even some conservatives and remainers are saying at least he's putting forward a positive vision. that was the whole point up the speech or article. to put pressure on theresa may not to give too much ground to what he sees as the philip hammond view that, or the labour party view, that after brexit we will essentially be in the same relationship with the eu as we were before. he doesn't think that's a sustainable position and he's making his view clear. 0bviously personal ambition comes into it as well.

because everybody thinks that theresa may will not be leading the conservative party into the next general election. everybody‘s state m e nts general election. everybody‘s statements now are against the background of that fact. boris johnson positioning for succession, as is amber rudd, and maybe even damian green. what did you make of amber rudd's intervention today. it was one of those standout moments of the referendum campaign when she said, he is great fun at the party but you don't want in driving new home at the end of the night. she resurrected that today. she and boris have history. she wouldn't say this, but she must be delighted boris has popped his head above the parapet for her to take pot shots at so she can impress the conservative party faithful with her loyalty to the prime minister and her good sense. i thought she performed extremely well in her interview this morning. she sounded calm and

controlled and authoritative and it will do her leadership chances no harm at all. thank you very much, and we have the tory conference in a couple of weeks, so i'm sure this will be bubbling along then as well. the headlines on bbc news... the home secretary confirms the terror threat level has been lowered from critical to severe. police are searching a house in stanwell near heathrow after arresting a 20—year—old man in connection with the london tube bombing on friday. the home secretary — amber rudd — has accused borisjohnson of being a ‘backseat driver', following his newspaper piece setting out his views on brexit. in sport lewis hamilton extends his lead in the drivers chairmanship in formula 1 after sebastian vettel‘s ferrari hit max verstappen in a crash close to the start of the race. hamilton extends his lead to 28 points. chelsea and arsenal are drawing 0—0 at stamford bridge in

prime minister. that's exactly right. the party won just over 7% of the vote at the general election a few months back. but the new leader saying he could plausibly be the new prime minister. that would need the party to pick up a considerable numberof party to pick up a considerable number of votes. it's true they have picked up a lot of new members after the eu referendum and since the general election this year, but i think lots of people have been raising their eyebrows that it was a realistic prospect to see vince cable in numberten. and as realistic prospect to see vince cable in number ten. and as new leader he has an almighty challenge on his hands. you would think with lib dems, the most pro—eu party out there, they would have the pick of there, they would have the pick of the 48% of people who voted to remain in the election, but it did not give them the result they wanted. they went from eight mps up to 12, but their vote share dropped. vince cable's comments on becoming a future prime minister sets out an ambitious challenge, but he thinks

it could happen. it's possible. it's very unlikely. we could break through. if british party politics brea ks through. if british party politics breaks up, if ‘s traditional structures starts to break up, and it could happen, we are extremely well positioned with moderate, sensible policies. a good track record in government. we have government experience and experience at local level. i think we will find at local level. i think we will find a big shift in our direction. i'm very confident talking about being the prime minister. one of the things vince cable and the party hopeis things vince cable and the party hope is that their message on brexit, on a future referendum on whatever deal the government gets in those negotiations with brussels will cut through to voters. that's where they hope they will pick up some ground. they believe that with labourunderjeremy some ground. they believe that with labour under jeremy corbyn being taken further to the left, there is a big, gaping hole in british politics that is there for the taking. the new deputy leaderjo swinson was talking in the main

auditorium this afternoon and she has been telling members she thinks it's right that they press for the government to give voters another say on whatever deal theresa may gets from brussels. politics feels broken. to me, to many in this room, and to so many far beyond this conference hall. we are absolutely right to fight for an exit from brexit. applause. brexit will make it harder to follow our values, to protect human rights, to tackle climate change. to solve global problems. an exit from brexit is necessary, but it is not sufficient. because this culture clash continues. and the populists stoke this tension. they do it deliberately. they talk in simple soundbites that scapegoats different groups. it's all someone else's fault.

as liberals we know this is nonsense. the farage—y, trump—y, angry, as—he. shouty slogans aren't a solution to anything. the liberal democrats are pretty positive. i find that these party conferences they always manage to put a positive spin on things. but i think the shine of that positivity hasjust gone a think the shine of that positivity has just gone a little think the shine of that positivity hasjust gone a little bit compared to this time last year. and that is a demonstration of just to this time last year. and that is a demonstration ofjust how big a challenge for vince cable is. at 74 years old, we thought his political career was over. he was busy years old, we thought his political career was over. he was busy writing novels and dancing. we saw him do ballroom dancing competitions. now his life is very different and he carries a big challenge that the lib dems face. eleanor garnier at the

liberal democrat conference in bournemouth. there's been a sharp increase in the number of firefighters unable to work because of mental illness in england and wales. figures obtained by bbc radio 5 live suggested a rise of nearly a third over the last six years. in london, the number of fire staff taking leave because of mental health problems has doubled since 2011. the home office said it was the responsibility of fire departments to put wellbeing support in place. jill tolfrey is the chief executive of the fire fighters charity. i think actually as a british culture we are not terribly keen to identify that we have a mental health issue. and firefighters are very much seeing themselves as the rescu e rs very much seeing themselves as the rescuers of other people. they don't see themselves as portraying any weakness. so add those things together and it's actually quite difficult for them to suggest they are suffering from stress, anxiety, orfrom some of are suffering from stress, anxiety, or from some of the things they have seen throughout their working life, that that's having an effect on. but

actually you would expect it to have an effect on them because they see some pretty terrible things. it wouldn't be a human response not to be affected by some the things they see. korea aid agencies working with rohingya muslim refugees the un secretary general antonio guterres has urged myanmar‘s leader, aung san suu kyi, to end the military offensive. in an interview with the bbc‘s hardtalk programme, he said that she had a chance to reverse the situation when she addresses the nation on tuesday. it is clear for me that we have two dimensions here. 0ne dimension is that this is not

a perfect democracy, this is a situation in which the military still has the upper hand. so you are blaming the military, not aung san suu kyi? i am saying it is a complex situation. could you clarify. who is responsible? it is a complex situation. it is clear for me that there is pressure from the military side to do what is being done on the ground. i would expect that the leader of the country would be able to contain it and would be able to reverse the situation. she has a last chance in my opinion to do so because she will be addressing the country and i hope that it corresponds exactly to the beginning of our high—level session in the general assembly. she will have a chance to reverse the situation. if she does not reverse the situation now, then i think the tragedy will be absolutely horrible. unfortunately, i don't see how this then can be reversed in the future. you don't see how this can be reversed? i think it still can be reversed, i think she still has an opportunity next tuesday.

but can she tell the military to stop what is going on on the ground? you just blamed the military and not her. i think we also have to put pressure on the military. i think it is important that countries that have links, military to military, do so. i think all forms of pressure are necessary at the present moment in order to make sure that the carnage stops. the un secretary—general speaking there. 0ur correspondent in myanmar, jonah fisher, says the nationally televised speech that aung sang suu kyi will give in a couple of days will be a key moment. i'm sure antonio guterres realises the limitations and restrictions on aung san suu kyi's power. yes, she is the head of the civilian government here, but the burmese army is an autonomous political entity here and it does not take its instructions from the civilian government. the operations in the northern rakhine state that has driven so many of the rohingya into bangladesh, that is being carried out by the burmese army, not on the instructions of aung san suu kyi.

the criticism made of her is that she has not spoken out, she has not really reflected on what is going on in rakhine state in public, in terms of the tremendous suffering of more than a00,000 rohingya who have crossed the border into bangladesh and are now in pretty dire conditions. on tuesday, when she speaks here, she is giving an important speech in front of diplomats here, and she will speak in english — clearly tailored for an international audience. the diplomats and international audience watching around the world will listen closely to see how she calibrates that message and people will listen in to see if there is an acknowledgement of the tremendous suffering, the awful things that have taken place. there have been horrendous reports of abuses taking place at the hands of the burmese army in northern rakhine state. i think people will be listening closely for an acknowledgement from aung san suu kyi aboutjust how serious things are and bleak for the rohingya population

and her challenge will be how to calibrate that message so she maintains a relationship with the burmese military — she has to work with them day—to—day — while also satisfying an international community that has become increasingly harsh in its criticism of the way in which she is responding. early i spoke to a spokesperson for the un refugee agency who described her experience in a refugee camp in bangladesh. i was most rigged by the refugees themselves, the gestures of solidarity and humanity. refugees who have just arrived, trying to find a place. there were quite beautiful moments of humanity. but the fact still remains that there is a commend this amount of need on the

ground, emergency shelters, food, clean water and medical care. as i was walking around the camp, every few steps i took, somebody would stop me and point at a wound or need. we met a woman who was over 60 years old who had to be carried over the water by her two sons because she was paralysed and is in desperate need of medical care. there is a lot of that on the ground and many of the aid agencies, in cooperation with the locals and the bangladeshi government, are addressing those urgent needs. police are continuing their investigation into a crash on the m5 in south gloucestershire yesterday in which four people died. a woman and two children are critically ill and remain in hospital. tomos morgan reports. it's been described as an utterly horrific crash. and one that has already claimed four lives. at 2:30pm yesterday afternoon, a lorry travelling southbound on the m5 motorway crashed through the central reservation

between junctions 15 and 1a, just north of bristol. it hit at least two vehicles travelling northbound in a high impact collision. four people were killed and three others, a woman and two children among them, were taken to hospital in bristol with life—threatening injuries. is there any idea at the moment what caused the 18 tonne lorry to crash through the central reservation? there are a number of lines of enquiry we are looking at. one of those is the vehicle itself, are there any defects on the vehicle which caused it to lose control. that's a significant line of enquiry for us at the moment. police here today at the scene say due to the severity of the collisions, the clearing of the scene is taking longer than expected. the northbound route between junctions 16 and 1a remains closed as the police carry out their investigations. the southbound route, though, has reopened. emergency services have commended members of the public who courageously went to the aid of those involved in this horrific crash. tomos morgan, bbc news, tytherington. time for a look at the weather now.

it's been another cool september day for the time of year and another showery day with downpours across central and eastern england. showers are still with us during the evening but was fade away overnight. low cloud moving in across central, eastern and southern england. mist and fog patches will also form. that will leave the north—west of the uk with the clearest skies overnight. it's here where we will see lowest temperatures. towns and cities at ten or 11 degrees, but in the countryside, the coldest spots in scotland, northern ireland, north england could get down close to freezing. chile first thing monday morning, but quite a bit of sunshine for many of us as well. we will see

showers develop in the late morning and early afternoon. central and eastern england will see the bulk of the showers with more general rain heading to the far north—east of scotland. along that it will feel quite cool with highs ofjust 12. quite cool with highs ofjust12. 0ther quite cool with highs ofjust12. other than that, 15—18 are top temperatures. hello, this is bbc news. the headlines at 3:30pm. the home secretary has confirmed the terror threat level has been lowered from ‘critical‘ to ‘severe'. police investigating the london tube bombing have arrested a second man — he's 21 and was detained in west london last night. the home secretary, amber rudd, has accused borisjohnson of being a ‘backseat driver‘ following his newspaper piece setting out his views on brexit. meanwhile, borisjohnson has been criticised for a ‘clear
