a warning that time is running out to finalise a test, track and trace strategy that would avoid a potential second surge in coronavirus cases. nhs leaders also criticise government plans which they say bypass primary—care staff on the front line. if they don't know how they're going to interact with this completely separate operation that is being set up in terms of tracers, then effectively we're going to kind of miss a whole bunch of opportunities. we'll be getting reaction to the criticism from westminster. also this lunchtime: scotland's first minister announces an easing of lockdown restrictions but says they must be cautious. we view them as a proportionate and are suitably cautious set of first steps, and i hope that they will bring some improvement to people's

well—being and quality of life, started to get our economy moving again, and started to steer us safely towards a new normality. borisjohnson is cleared of any criminal actions in his relationship withjennifer arcuri whilst london mayor, but a review establishes there may have been an intimate relationship. six weeks ago, karen mannering was fighting for her life with covid—i9. we meet her as she returns to hospital to thank the staff who saved her life and her unborn child's. and coming up on bbc news, it could be next summer or never for the tokyo games, as olympic president thomas bach tells the bbc it's unlikely they'll be postponed again.

good afternoon and welcome to the bbc news at one. the government has been warned of severe consequences for the health service in england if its covid—i9 test, track and trace system isn't in place soon. the nhs confederation says any further easing of the lockdown depends on a clear strategy and a delay will risk a second peak of the infection. the prime minister has pledged to have what he's called "a world—beating" contact tracing system up and running by the first ofjune. our health correspondent lauren moss reports. test, track and trace — three words we've heard a lot during the pandemic, three words that will be key to controlling the spread of covid—i9. but now those representing hospitals, health and social care members, have warned that if the system isn't ready soon, there is a risk of a second peak. if you don't

go further and you make further relaxations, then obviously the danger of the r number, which the government absolutely recognises, the danger of the r number rising becomes greater if you have not got in place effective test, track and trace processes. boris johnson has promised a world beating tracing system will be in place by the ist ofjune, the same day that nonessential shops and schools could gradually reopen. there will be 25,000 trackers able to cope with 10,000 new cases a day, and that is very important. so how does it work? trackers will contact people who have been in the company of someone who has the virus. they will alert them by phone call, text or e—mail and give advice. a new nhs app will notify anyone who has downloaded it that someone they have recently been near has tested positive. the phone app is particularly advantageous is

that it helps you identify, as you previously said on the news, the people you may have trialled around a supermarket with or been on public transport with, and it is looking at how long someone has been in contact with as well. about the clock is ticking. the government had hoped to roll the app out by the middle of may. it is still being piloted on the isle of wight. we are working at huge pays in relation to the app itself, and therefore having put that in place, now trialling it on the isle of wight, and whilst i am unable to give you that definitive timeline this morning, please be in i'io timeline this morning, please be in no doubt as to the extent, the effort, the energy, the focus that is being put on that as well. the office for national statistics' surveillance programme suggests there may currently be 8700 new infections a day in england. 177,000 we re infections a day in england. 177,000 were provided on tuesday, having the capacity to deliver 200,000 a day is

the end of may target. but there are cause for clarity about how nhs workers will make use of the tracking system. nobody in the nhs knows how they are going to interact with this new track and trace operation, so i hear the prime minister saying the 1st ofjune, but equally what you have heard in the last 2a hours is a whole load of behind—the—scenes briefing and individual cabinet ministers and, actually, we are not quite sure when injune. actually, we are not quite sure when in june. different parts of britain are easing out of lockdown at varying speeds. northern ireland, wales and scotland are trialling or implementing test, track and trace programmes. those three words pivotal to what happens next across the uk. lauren moss, bbc news. our assistant political editor, norman smith, is in westminster. as an act report, the clock is ticking on this. it is, because if the off does not meet its deadline for getting the system up and running, there will not be any early

easing of the lockdown, worse, there isa easing of the lockdown, worse, there is a danger of the virus is surging again, and possibly the need for a second lockdown, which is why the government has taken a huge decision to press ahead with a more basic system of test, track and trace, one relying on human contact tracing, a little army of officials, 20,000 or so, rather than waiting for the most sophisticated phone app to work. so what would happen is if i tested positive for coronavirus, detractors would say to me, who have you been in contact with over the past fortnight? —— i would say i have beenin fortnight? —— i would say i have been ina fortnight? —— i would say i have been in a house with my wife, i have sat close to editor a and researcher b, andi sat close to editor a and researcher b, and i went down to get a paper. the trackers would get on the blower, or even go down to visit the newspaper people to say, all you people, you need to self—isolate. what that system doesn't do is enable you to contact strangers, which the phone app does do. so the

person opposite on the train, i don't know who they are, but the phone app would because it would register their details. the government have taken the decision to press ahead because time is pressing, we can't wait for the it boffins to sort this out. secondly, i think there is a fear that if they did go ahead with a dodgy phone app, people would think it was a shambles, they wouldn't bother to engage with the test, track and trace system. so they have gone for the more basic approach, but a huge amount is riding on this and on having it working byjune the 1st. norman, thank you very much, norman smith. scotland's first minister has outlined a plan for exiting lockdown. from next week, restrictions around some outdoor activities will be relaxed. let's get more from our scotland correspondent lorna gordon, who's in glasgow. the first minister announcing this in the last few minutes. she has been speaking in front of the scottish parliament, giving more details of how the lockdown will be eased in scotland. it will be a four

stage process, she said, very cautious, very gradual, it will not be the flick of a switch, but the first measures in his easing will start from the end of next week. primarily, they first phase has an outdoor focus, she talked, primarily, they first phase has an outdoorfocus, she talked, the first minister talk to people being able to sit in parks and outdoor areas, that people can meet others from other households as long as it is outside and that these social distancing rules are maintained, some non—contact sports will be allowed, fishing, golf, tennis, bowls, for instance, outdoor businesses such as agriculture and forestry and construction will be able to restart, and garden centres and recycling facilities will also be able to reopen as well. these phase one measures, most of which have an outdoor focus, are not in place yet, let me stress that, and they are dependent on us continuing to suppress the virus. they will also be monitored carefully as they do take effect.

however, we view them as a proportionate and suitably cautious set of first steps, and i hope that they will bring some improvement to people's well—being and quality of life, start to get our economy moving again, and start to steer us safely towards a new normality. of interest to a lot of people will be the detail is the first minister gave on schools. she confirmed they won't reopen until after the summer, but remember, scottish terms, the summer term finishes earlier and sta rts summer term finishes earlier and starts earlier, the autumn term sta rts starts earlier, the autumn term starts earlier, the autumn term starts earlier as well, but she said that schools will reopen from the 11th of august here in scotland, and it will be a blending of part—time schooling and home learning. so a route map to some form of normality going forward, but it will be very gradual and very cautious. lorna gordon, thank you very much. the prime minister will not face a criminal investigation into his relationship with the american businesswoman

jennifer arcuri while he was mayor of london. our home affairs correspondent daniel sandford is with me now. does this mean he is out of the woods? he is out of the criminal woods? he is out of the criminal woods for now on this, but he will still face an investigation by the oversight committee of the greater london authority. the allegation was that his close relationship with the american businesswoman jennifer arcuri had meant that she had somehow got money and trips, access to overseas trade missions because of that close relationship. what the independent office for police conduct found was that there was no evidence he had influenced those decisions. however, what it did find was that those around borisjohnson believed there was a close relationship between the two, and that may have influenced how they behaved, and the independent office for police conduct also found that there was definitely a close association between borisjohnson and jennifer arcuri, and i may have been an intimate relationship, and as they put it, it would have been wise for boris johnson as they put it, it would have been wise for borisjohnson to have declared this is a conflict of

interest. they went through 900 documents, eight years of e—mails to work out whether they should be a criminal investigation, and they did make this little afterthought. some of the records which would have assisted the review either never existed or have been deleted, and i had lots to say about the record—keeping at the mayor of london's office while borisjohnson was there. daniel, thank you very much. in normal times, tomorrow would have been one of the busiest days for british airports, as families head to the sun for may half term. but with most flights grounded, the airline industry is looking at ways to allow flights to resume. heathrow, the uk's busiest airport, will introduce temperature checks for travellers at one of the airport's terminals. jon donnison reports. if people are going to be flying again this summer, this will be the new normal — he threw the latest uk airport to be trialling body temperature scanners. —— heathrow. as you come into the departures area, we will have a thermal scanner which will pick up whether you have

a heightened temperature, and if you do, we will take you to one side, andi do, we will take you to one side, and i will be a series of questions and i will be a series of questions and test to see if you are fit to fly. and if you are not, then depending on the circumstances i doubt we will work with public health england to make sure you are looked after, or you mightjust go home and quarantine, as we all are doing at the moment. then there is theissue doing at the moment. then there is the issue of quarantine, which the government says will be introduced next month. anyone returning to the uk or visiting from abroad will have to self—isolate for two exams provide the address. there will be an exemption for the republic of ireland, but not france, as the government had first suggested. the boss of rya nair, government had first suggested. the boss of ryanair, who wants to resume 40% of flights in july, boss of ryanair, who wants to resume 40% of flights injuly, has called the quarantine policy laughable and unenforceable. the boss of heathrow is not far behind. well, the current plan is that everyone would be quarantined, and that will effectively be for the foreseeable

future, so it can't be a solution for more than a few weeks while we get the crisis in health under control. but then we need a plan for how we will open our borders again, allowing people from countries that have very low risk of infection to come to the uk, and for people from the uk to go to those countries. but will the world's tourist resorts wa nt to will the world's tourist resorts want to visitors from britain, which is at the highest number of coronavirus deaths in europe? spain opened up some of its beaches or logos this week but i said anyone visiting from overseas will have to undergo two weeks' quarantine. greece, with its idyllic islands, also has a quarantine in place and says it wants to open up its tourism sector from next month, says it wants to open up its tourism sectorfrom next month, as says it wants to open up its tourism sector from next month, as does italy. from june the 3rd, the country will be open again to travellers coming from the uk, from the european union countries and the schengen countries, and we are going to do that also together with some measures to make sure that when

people come, they feel in a sort of safe environment. flights have now been grounded for almost two months, and while uncertainty about quarantine here and abroad remain, the summer holiday season seems most likely to be a domestic one. jon donnison, bbc news. with foreign holidays looking increasingly unlikely for some this year, many of us are looking for a destination closer to home. and the warmer weather has meant the uk tourism industry is facing a surge in demand. our consumer affairs correspondent sarah corker has been finding out how they are preparing on the home front. rural retreats. isolated destinations. many arguably ready—made for social distancing. on the edge of the north york moors, jolly days glamping is hoping to benefit from a bump in bookings as uk holidays become the only option for many. yeah, we would like to open now! because it is a huge area.

social distancing isn't a problem. after a quiet spring season, carolyn is starting to hear from customers making tentative summer plans in the hope lockdown will be relaxed in the coming months. we've already had bookings that are starting to come in. we've got an awful lot of inquiries that are coming in as well, particularly over the last couple of weeks, as obviously the weather gets nicer and people start to look ahead. we are optimistic that things will start to pick up really quite quickly once we are able to open. with foreign travel off the table for now, holiday lets and camping sites in places like yorkshire and the lake district stand to benefit from britons scaling back their holiday plans. we are expecting a boom, to be honest, it is a beautiful county we are in today. it's a beautiful country, and many people choose the uk as their holiday destination, so it's on our doorstep. in the absence of international travel, let's get out into the countryside, the coastline, and really cherish what's on our doorstep. so i think when it's

safe and right to do so, restrictions must be eased. it's notjust big summer getaways that have been affected. popular spots for day trips across the uk have also been shut for weeks. there is, though, a growing number of organisations who say they can make social distancing work. among them english heritage, who manage over 400 historic sites. we think there are ways in which we can encourage visitors to come here, to feel comfortable in doing that, and for staff to feel comfortable as well. what are the pinch points, what are the places where people are going to pass by each other or handle things? and just have a good safety regime in that. but it's also very much about not overburdening the experience, making people feel comfortable and reassured and able to relax, cos that's what they have come here for. there is no question that the tourism industry has taken a massive hit from coronavirus. visit britain says the loss runs into billions of pounds. but with us all forced to swap barcelona for brighton

and corfu for cornwall, there is hope that the staycation may save not only the great british summer holiday but also many hundreds of businesses across the uk. sarah corker, bbc news, north yorkshire. the founder of facebook, mark zuckerberg, has defended its record of tackling misinformation during the coronavirus outbreak. speaking to the bbc in his first broadcast interview in five years, he said the platform removed all content which put people at "imminent risk of physical harm". mr zuckerberg's been talking to our business editor, simonjack. are there some permanent changes that you perceive from this, and what do you think that your company's role has been during the crisis? we've focused on three main areas. one is responding to the acute health crisis. the second is helping people stay connected with the people they care about.

and then the third area is on economic recovery. so right now we're seeing a lot of pain for small businesses. they're having a hard time staying open as a lot of people are staying home, and that means millions of people are losing jobs, and i think anything that we can do to help small businesses survive. if some crazy person decided to start telling people to, i don't know, drink or inject bleach or saying colloidal silver would be a good way of keeping the virus at bay, what is the facebook algorithm's response to that? things like saying that something is a proven cure for the virus when in fact it is not, we will take that down. another example which i know has been very prevalent in the uk has been 5g misinformation, which has led to some physical damage of 5g infrastructure. so we believe that that is leading

to imminent risk of physical harm, we take down the content. there have been hundreds of thousands of pieces of content like that. we have a us election coming up, and there was a princeton university survey saying that facebook is the fastest and biggest purveyor of misinformation in the us. do you think that facebook can influence the way that people vote? we've learned a lot about how politics works online since 2016, and there are many different threats we have worked hard to mitigate. for example, one big area that we were behind on in 2016, but now we are quite advanced at, is identifying and fighting these co—ordinated information campaigns coming from different state actors around the world, whether it is russia or iran, or in some cases china. in 2016, this was a new kind of tactic. it's not that there aren't going to continue to be issues, countries will continue to try to interfere, we will see issues like that. it's a little bit of an arms race

in that way, but i certainly think our systems are a lot more advanced now. i think in many ways more advanced than many other company or governments around the world, and ifeel confident about our ability to help protect the integrity of the upcoming elections. mark zuckerberg talking to simon jack. our top story this lunchtime. a warning that time is running out to finalise a test, track and trace strategy that would avoid a potential second surge in coronavirus cases. coming up — enjoying dressing up. the challenge for schools to get youngsters comfortable with face masks. coming up on bbc news, in sport, one former premier league striker warns project restart is at risk if players decide against returning to training amid fears over covid—19. they were images of a heavily—pregnant woman suffering

from covid—19 which you may remember — suffering from double pneumonia and struggling to breathe. karen mannering's video message urging people to respect lockdown restrictions was viewed worldwide. well, now, six weeks on, karen has returned to hospital — to thank staff who saved her life. colin campbell has been speaking to her. i literally can't thank you enough for the sacrifices you all make... it's a socially distanced but heartfelt thank you from a coronavirus patient to those who cared for in margate's oeqm hospital. it's just memories to look back on but obviously it's quite raw, i think. two months ago karen mannering, who is heavily pregnant, thought she was dying from the disease and posted a shocking video that was viewed all over the world. i'm six months pregnant, nearly, with my baby. i've just been told i have covid—19. just don't go out. it's not worth it.

that video went absolutely everywhere. yeah. and probably saved lives. yeah, i hope it did. why did you do it? well, i had my friend message me to say people are still carrying on, they're going to meet their friends, they are sitting down on sea walls and having a beer or going down the park, and i thought i'm here fighting for my life, for my baby's life, and i want people to know it's real, it's here, and it's incredibly painful and it will kill you. karen was admitted to hospital on the 21st of march after suffering at home for ten days with a fever and debilitating dry cough. i have pneumonia on both lungs and i'm fighting for me and my baby. she was diagnosed with the virus four days later, but made a speedy recovery. this is me sitting up, yeah! she was discharged after seven days but returned home, where she had to isolate from herfamily. i've been so ill since the 12th

of march and i get to go home. it's still busy, we're still getting patients in with coronavirus. they're still really sick. a nurse for a0 years, penny searle is one of the many nhs staff who cared for karen and the many others who have battled the disease in the qeqm. it's been frightening but think it's shown my own strength and courage and i've seen some inspirational work by fellow team members, by our trust. reunited with the heroes whose fight against covid—19 is ongoing, karen mannering is urging people to continue to social distance, to stop the spread of a disease that she feared would kill her and her baby — a baby that's due to be delivered here at the oeqm in six weeks' time. colin campbell, bbc news. every day we hear about the rising

number of people who have died with coronavirus — and now being remembered and mourned. go to bbc.co.uk/news to see tributes paid by family, friends and colleagues to some of those who have died. there is also a form where you can add your own tribute, if you have lost someone to the virus. a company working with the university of oxford on a coronavirus vaccine says it has the capacity to make 1 coronavirus vaccine says it has the capacity to make1 billion doses. astrazeneca says it's received money to make the vaccine in the united states. the us government has ordered 300 million doses of the potential vaccine and is committing more than $1 billion to help speed up more than $1 billion to help speed up the drug's development. it's emerged that more than 300 emergency workers have been assaulted across england and wales in cases linked to coronavirus. the crown prosecution service say they were among 660 covid—related offences last month. the director of public prosecutions described the attacks on police,

paramedics and nurses as "particularly appalling". the tokyo olympic games could be cancelled altogether, if they don't go ahead next summer. the games were re—scheduled because of the covid—19 crisis. the head of the international olympic committee, thomas bach, says their future is in doubt. he's been speaking to our sports editor dan roan. it's known as the greatest show on earth, but four years after the baton was passed to tokyo, the city's now trying to reorganise the first ever postponed games — the most powerfulfigure in olympic sports telling me the scale of the challenge facing the hosts is daunting. it's a mammoth task, and there is no blueprint for it, so we have to reinvent the wheel day by day. two months have passed since the games were put back a year because of the coronavirus crisis. with billions of pounds more being spent on rescheduling a scaled—back event, organisers have suggested next summer is tokyo's last chance.

you cannot forever employ 3000 or 5000 people in an organising committee. you cannot every year change the entire sports schedule worldwide of all the major federations. you cannot have the athletes being in uncertainty, you cannot have so much overlapping with the future olympic games. the olympics have seen many iconic moments, and all have been enjoyed in packed stadia, but amid concerns tokyo depends on a vaccine being found, bach did not rule out the possibility of an olympics behind closed doors. it's very much a speculation now. hmm. i think we will need a lot of consultation in this respect. of course, this is not what we want, because the olympic spirit

is about also uniting the fans, and it is what makes the games so unique. six months ago, we spent time with british canoeists as they visited the host city. what kind of games awaits them next year and whether such venues are ever used for olympic competition remains uncertain. dan roan, bbc news. plans are under way to allow more children to return to schools and nurseries in england from the first ofjune, but not everyone is happy at the prospect, raising questions such as how do you ensure young children stick to new safety rules? tim muffett has been to one nursery — for children of key workers — to see how they are coping. a fresh start, adapting a nursery to cater for a pandemic. the children have to wash their hands on arrival. we also have the parents drop off at the front door, so a staff member will come and collect them, rather than going into the nursery.

musgrove nursery in taunton has stayed open for the children of key workers. staff hope lessons learned here could be useful for other nurseries. so far, we haven't really focused on social distancing between the children, and we've just allowed them to play. because one of the main things children learn in nurseries is to play with other children. but we have been looking at staff contact. so if staff can space themselves out, listen to the two—metre distance, then we think adult—to—adult transmission might be kept down. this nursery‘s found if that staff wear face masks, it doesn't work. the children don't like them, they pull them down, because they want to see how we're speaking. and of course they're learning to speak. so we've piloted them, we're not wearing them with the children. some of the local secondary schools have used their 3d modelling to make visors, and it does mean if a child starts to cough and has a temperature, you know, in front of you, you could put this on and then protect yourself from the cough. if we can let these be in the environment so they can see them, then they won't be

so frightened if they actually have to see a member of staff using them. you're not routinely going to use these, but you're getting them used to them? exactly, so that if a child does start to cough and feel ill, then we can take the child to the side room, and they won't be frightened of some new kit they've never seen before. this nursery has been looking after around 30 children per day. typically, it's 90. lower numbers have meant it's easier to keep children in informal groups. that might get trickier. we've put the yellow tape down just in the last couple of days, planning ahead to, if we are going to have to encourage children to separate out a bit more once we're 70% occupied, rather than 20% occupied. so now we're being far more frequent with cleaning, and even if a child's handled a cuddly toy, for example, once they have put it down, they're finished with that, we'll whip it away to the laundry. more of the cleanliness, though, is focused on door handles and tablets that staff manage. those kinds of things are where the adults are going to keep touching the same thing. although this nursery has been caring forfarfewer

children than normal, it has at least had a taste of the challenges ahead. for those that have been closed completely, reopening will mean a whole new rethink. tim muffett, bbc news. time for a look at the weather. here's darren bett. it's warm today, not as warm as yesterday, mind you and it will cool off over the next few days. we are infora off over the next few days. we are in for a spell of stronger winds and rainfor in for a spell of stronger winds and rain for some although not necessarily where it's needed most. this cloud didn't bring much rain. this cloud didn't bring much rain. this looks more threatening, a deep area of low pressure and it will bring wet and windy weather. we'll start to see high cloud in western areas later. that's all that's left of the earlier rain heading into north—east scotland so for many of its it's going to be dry and sunny. for northern and western areas not as warm as yesterday but we are still making 27 in the south—east in

the sunshine. it should be a fine end to
