heading abroad for some sunshine could see you facing a £5,000 fine. the government says new coronavirus laws due to come into force next week will target people from england travelling without good reason. 0ur transport correspondent caroline davies reports. the empty beaches may be calling, but they aren't in reach yet. holidays are already illegal and anyone travelling abroad needs to have a declaration form. in addition, on monday, when the stay at home rule ends, the government plans to introduce a £5,000 fine for anyone travelling internationally without a legally permissible reason. those include work where it is not reasonably possible to do it from the uk, study where it is considered necessary, elite sports, for training or competition, medical, such as a clinical appointment, funeral or wedding of a close family member living outside the uk. these are very similar to the existing rules. this doesn't include visiting grandparents, so,

families like this one, whose parents are in poland, will have to wait to be reunited with their grandson. we mention grandma and grandpa and the rest of the family, and hejust goes kind of quiet and silent and withdraws, and it is worrying me. are involved who perhaps haven't met or haven't seen their close family. the law could be in place until the 30th ofjune, but the government say this doesn't change the timeline where international travel could restart on the 17th of may. i entirely understand people's yearning to get away and have a summer holiday, and we're looking at that question right now, as part of the global travel task force, as it's called, which will report in the middle

of next month, and we... the earliest that we will take any steps will be the 17th of may. but some in the travel industry are worried that this is sending mixed messages. it's just so frustrating. finally, there is some light at the end of the tunnel, we had some optimism, and then the travel industry wakes up to headlines like this. itjust creates more uncertainty, when actually we still don't know anything. all of this speculation is exactly that, it is speculation, until the travel task force reports back on the 12th of april. to have these fines come in right now, it's just another blow. if the government wanted these draconian measures, they should have been introduced back when international holidays were first banned, it is more scaremongering. the industry is keeping its eyes fixed on the government's next announcement in the hope that it will bring them certainty and brighter news. caroline davies, bbc news. throughout the past 12 months we've all become familiar with public health messages aimed at saving lives and protecting the nhs. there have been huge medical advances — as day by day scientists have gained

more knowledge about how to tackle coronavirus. this morning, there was the further good news that the number of weekly deaths in england and wales has fallen below the five year average for the first time since last august. our health correspondent catherine burns reports. know your enemy, that's the first rule of warfare. but as our battle began, coronavirus was new and unfamiliar. as the prime minister reminded us, the main weapons most of us had more soap and hot water. two verses? from the start the berry was making sure that the health service would not collapse under the pressure. fist service would not collapse under the ressure. �* ., , , pressure. at the worst case scenario. — pressure. at the worst case scenario, the _ pressure. at the worst case scenario, the nhs - pressure. at the worst case scenario, the nhs would i pressure. at the worst case | scenario, the nhs would not pressure. at the worst case - scenario, the nhs would not cope with the number of ventilator beds that were required, nor could any health care system. bud that were required, nor could any health care system.— health care system. and so that s stem health care system. and so that system braced _ health care system. and so that system braced itself, _ health care system. and so that| system braced itself, conference halls were converted to field hospitals, in the end though the nightingale hospitals were barely

0ne one year 0ne yearon and one year on and unlike the situation 12 months ago, we do now have hope? we do, absolutely, because of that vaccine roll—out and what we also haveis vaccine roll—out and what we also have is the lockdown easing plan which begins from next monday. so all of that is in place but what we don't know is still many things and the labour party today, therefore calling for this inquiry, you heard sir keir starmer saying lessons need to be learned and they have criticised the government for being slow at points. remember, we have one of the highest cumulative death tolls in the world, one of the highest per capita death tolls, one of the deepest economic downturns. the government says it has learned and now is not the time to look into things and it is now considering new measures so things like whether there should be compulsory vaccinations for all of those working in care homes. there will be a consultation on that. care homes

are calling for it. care home staff, there is a concern about forcing them to do it. remember, a quarter of them have not been vaccinated but there have been tens of thousands of deaths in care homes. more things we are not clear about exactly, you heard travel, when will foreign holidays happen? not before the 17th of may. we know the government is cautious on that and the continued supply of vaccines, everything depends on that which is why the government is busy trying to talk to the eu to ensure that happens. damian, thank you. and borisjohnson will lead a downing street news conference on coronavirus this afternoon. coverage starts on bbc one and the bbc news channel at 4.30, with the news conference due at 5. as a third wave of coronavirus infections spreads across europe, the german government has announced it will extend its current lockdown for a further three weeks. restrictions will be even tougher for five days over easter, with many religious services cancelled. 0ur correspondentjenny hill is inside a vaccination centre in bremen.

all but been cancelled. meanwhile, the frustration over a shortage of vaccines continues here. you will recalljust vaccines continues here. you will recall just last week, vaccines continues here. you will recalljust last week, the german government temporarily suspended the use of the astrazeneca vaccine, it's started again but there are concerns that many people simply won't want to take it now. we've asked staff here what they think, they say they will take any vaccine they can get right now. people have been nervous about taking it. staff here said on the weekend when they started to get the weekend when they started to get the astrazeneca vaccine again, ten people out of 3000 did not show up for their appointment. people out of 3000 did not show up fortheirappointment. it people out of 3000 did not show up for their appointment. it gives you an idea, but if you stand here, look at the empty seats behind you, look at the empty seats behind you, look at the empty seats behind you, look at the case number is rising, you see by so many people, they're frustrated and concerned and it feels like germany is in a race against time. jenny, thank you. our top story this lunchtime. the uk falls silent on the anniversary of the first lockdown, as the queen reflects on the "grief and loss

felt by so many". and coming up — signs that thejobs crisis caused by the pandemic might be stabilising, but younger workers are still being hit hard. coming up on bbc news — the former huddersfield, leicester and bolton striker frank worthington has died at the age of 72. he had been suffering with dementia. former leicester striker gary lineker described him as his boyhood hero. scotland's first minister, nicola sturgeon, has been accused of misleading a scottish parliament committee which was looking at the way harassment allegations against alex salmond were investigated. a report from msps has also called the scottish government's handling of the investigation "seriously flawed". a separate report by a senior lawyer yesterday cleared the first minister of breaking the ministerial code. 0ur political correspondent nick eardleyjoins us from holyrood. nick? simon, in the last few weeks,

the committee said the handling of complaints was seriously flawed, that ms sturgeon misled the committee on meetings examined, a potential breach of the ministerial code and that her account of when she found out about concerns about mr salmond was hard to believe. well, first of all it is a shame that a committee report of this nature has become tainted by very obvious political bias, along party lines, in some conclusions. but actually, where there are reflections, and the government has always said, we made mistakes when it comes to the implementation of the procedure. relating to alex allan. we have got to learn from that and hold our hands up. the fact that and hold our hands up. the fact that the independent _ that and hold our hands up. the fact that the independent adviser - that and hold our hands up. the fact| that the independent adviser cleared ms sturgeon means herjob is safe, but with just ms sturgeon means herjob is safe, but withjust six ms sturgeon means herjob is safe, but with just six weeks until scotland goes to the polls, the political questions will continue to be asked. the committee report also includes testimony from two women who originally complained about mr salmond. they raise concerns about

the situation being politicised. 0ne also raises concerns about the lack of support from the government. snp members of the committee have distanced themselves from many of the findings, but opposition members say the conclusions leave big questions. we say the conclusions leave big questions-— say the conclusions leave big ruestions. ~ ., ., , ., , ., questions. we want to stand up for the work of — questions. we want to stand up for the work of a _ questions. we want to stand up for the work of a parliamentary - the work of a parliamentary committee that has thoroughly investigated this matter, has come to conclusions about catastrophic failures_ to conclusions about catastrophic failures within the scottish government, and has also come to the conclusion_ government, and has also come to the conclusion that nicola sturgeon misled — conclusion that nicola sturgeon misled the scottish parliament. so, we think_ misled the scottish parliament. so, we think the right thing for her to do now— we think the right thing for her to do now is— we think the right thing for her to do now is to step down. at we think the right thing for her to do now is to step down.— we think the right thing for her to do now is to step down. at the heart of our inquiry _ do now is to step down. at the heart of our inquiry are — do now is to step down. at the heart of our inquiry are two _ do now is to step down. at the heart of our inquiry are two female - do now is to step down. at the heart of our inquiry are two female civil. of our inquiry are two female civil servants, female seven servants, being, hence of the failed by the scottish government, and three years on, no one, but absolutely no one, has taken responsibility for that. nicola sturgeon still faces a confidence vote in the scottish parliament this afternoon, but she will win it, with support from the greens. this has been an incredibly

tumultuous time in scottish politics, and there is still the question of whether we will hear from alex salmond again. remember, this is a row between two of the most senior figures this is a row between two of the most seniorfigures in this is a row between two of the most senior figures in the independence and snp movements in recent years. but in six weeks' time, it will be up to the electorate here to make their own decision on how this has all panned out. nick, thank you very much. there are signs that the jobs crisis caused by the pandemic might be stabilising. the number of workers on employers' payrolls rose slightly by 68,000 in february, compared with the previous month. the furlough scheme has protected manyjobs but the total is still dramatically down year on year, as our economics correspondent andy verity reports. it is lockdown sectors from entertainment venues to restaurants where business has plummeted in the pandemic, and it is overwhelmingly young people who have lost their jobs. 0ne young jobseeker we spoke to from dumbarton has not worked for a year. in

outside the store. among the dead was local police officer eric talley, an 11—year veteran of the boulder police force. 0fficer talley was the first on the scene, and he was fatally shot. i also want to commend the heroic actions of the officers responding not only from boulder pd but from across the county and other parts of this region. police officers' actions fell nothing short of being heroic. pictures from the scene showed a middle—aged man, shirtless and dressed in shorts, being led away from the grocery store in handcuffs. one of his legs appeared to be coated in blood. officials will not confirm if he was the gunman, nor will they comment on a possible motive. they're pulling onto broadway here. as swat team officers converged on the scene, the white house said president biden had been briefed on the incident. last month, on the third anniversary of a mass shooting in florida in which 17 people

died, he called for background checks on anyone seeking to buya gun, and a ban on assault weapons. but this is the second mass shooting in this country in the space of a week, and it has already prompted calls for a new national conversation about gun violence. senator amy klobuchar, a member of the senatejudiciary committee, tweeted. .. "back to normal cannot mean a return to horrific gun violence. the committee has a hearing on gun safety tomorrow. we must put a stop to this." the state of colorado is no stranger to gun violence. 12 people lost their lives in the city of aurora in 2012 after a gunman opened fire into a crowded cinema. 13, when two students stormed into columbine high school before killing themselves. but the right to own a gun is enshrined in the constitution here, and those seeking a change in the law have had their attempts thwarted many times before. david willis, bbc news, los angeles.

now, some potentially earth—shattering news. it's to do with physics, and apparantly it could change our very understanding of the world around us. they've done something at the large hadron collider at cern in switzerland which has got scientists extremely excited. this report from our science correspondent pallab ghosh. the large hadron collider was built to discover brand—new particles, and transform our understanding of physics. by crushing particles together harder than they have been smashed before, the researchers there may have done just that. they have observed subatomic particles behaving in a way that can't be explained by the current theory of physics. scientists may have made one of the biggest discoveries in physics. lode one of the biggest discoveries in -h sics. ~ . , one of the biggest discoveries in .h sics.~ ., , , physics. we were literally shaking. we were shaking _ physics. we were literally shaking. we were shaking like _ physics. we were literally shaking. we were shaking like a _ physics. we were literally shaking. we were shaking like a leaf, - physics. we were literally shaking. we were shaking like a leaf, the i we were shaking like a leaf, the first time we looked at these results, because if it turn does

applause. i've taken a test, that has come out positive. the prime minister's condition worsened and on the advice of the medical team who's moved him to a critical care unit. the current measures must remain. it's going to take a long l time and i think we need to be aware of that. we agreed we should go for a short drive to see if i could drive safely. national hibernation is beginning to come to an end. the virus has started to spread again in an exponential way. we must act now to contain this autumn surge. you'll be able to form
