the eu backs down from using emergency brexit measures —— the -- the eu —— the eu faces mounting criticism. we were told that under no circumstances could the eu countenance a border between northern ireland and the republic but 29 days into the protocol they are happy to suggest it. the world health organization again warns against vaccine nationalism over the row about eu export controls. it is morally wrong, it will not help.

the prime minister publishes an open letter to parents, saying he's "in awe" of the way they're coping with home schooling. confusion over coronavirus rules in maternity wards midwives warn a lack of clarity means some staff are being abused. five men have been arrested following a disturbance at a former military barracks in kent. and coming up click looks at diagnostic devices that are becoming available, so family physicians can provide a full consultation remotely. that's at 3.30. the european union is facing criticism from politicians across the uk over its now abandoned

plan to override the post—brexit withdrawal treaty to impose export controls from the eu to northern ireland as part of efforts to control the export of coronavirus vaccines. northern ireland's first minister, arlene foster called it "an incredible act of hostility towards those of us in northern ireland". the plans had been part of the eu's new export controls on vaccines, to combat delivery shortfalls. following talks with borisjohnson, european commission president ursula von der leyen tweeted that the uk and eu had "agreed on the principle that there should not be restrictions on the export of vaccines by companies where they are fulfilling contractual responsibilities". and today, the world health organization has criticised the eu's announcement of export controls on vaccines produced within the bloc, saying such measures risked prolonging the pandemic. our political correspondent leila nathoo reports. how to avoid border checks between northern ireland and the irish republic was the issue that dominated the brexit

negotiations, but last night the prospect of a hard border on the island was raised again after the eu activated an emergency provision in the brexit deal in frustration over the pace of its vaccine roll—out. it's an absolutely incredible act of hostility towards those of us in northern ireland. it was nothing to do with making sure that northern ireland was in a peaceful state and all to do with the eu's vaccine embarrassment and mismanagement. the prime minister now needs to act very quickly to deal with the real trade flows that are being disrupted between great britain and northern ireland. the eu announced controls of exports of vaccines produced in the bloc and wanted to stop any doses entering northern ireland as a back route into the uk, but the commission quickly reversed its decision after condemnation from westminster, belfast and dublin. there is a joint duty of care.

we need to apply that rigorously in northern ireland and we need to have that spirit of cooperation across the new relationship that we have with our eu friends and partners. the eu is scrambling to secure vaccines for its member states. it's in a dispute with the firm astrazeneca about whether doses should be diverted from the uk to the continent to meet commitments already made. late last night the european commission's president, ursula von der leyen, said she had had a constructive conversation with borisjohnson and they had agreed there would be no export restrictions when companies were fulfilling contractual responsibilities. downing street said last night that the prime minister had grave concerns about the potential impact of the eu's actions, but ministers maintain they are confident in the uk's vaccine supplies. number ten is yet to comment on the eu's reversal over northern ireland. but this episode risks souring relations, fuelling suspicion of brussels in westminster

and raising concerns about how the eu may behave in the future if its interests are threatened. alexander stubb is former prime minister of finland and professor at the european university institute in florence. hejoins me now from es poh in finland. i wonder if i could firstly ask about your feelings about the way in which the eu commission has acted in this episode. i which the eu commission has acted in this episode-— this episode. i guess it is best to tell ou this episode. i guess it is best to tell you where _ this episode. i guess it is best to tell you where i _ this episode. i guess it is best to tell you where i come _ this episode. i guess it is best to tell you where i come from - this episode. i guess it is best to tell you where i come from on i this episode. i guess it is best to i tell you where i come from on this, i am very pro—european, i was against brexit, my wife is british, my children have dual nationality and i have family in the uk. but i do think the eu made a mistake. the measures were contrary to the principle of what european integration is all about and i think

against the ethics of how this pandemic should be dealt with so i am glad they withdrew the proposal. what happens do you think? did they panic? what happens do you think? did they anic? ., , ., ., ., panic? there was a tit-for-tat between the _ panic? there was a tit-for-tat between the european - panic? there was a tit-for-tat - between the european commission and astrazeneca which turned into a tit—for—tat between the eu and uk and i think some people were still somehow living in the final stages of the brexit negotiations under the new deal and forgot that with new reality comes new cooperation. i think it was a big mistake and i hope the eu comes back with some conciliatory measures. this pandemic is transnational, it goes across borders and it needs transnational ways of dealing with it. simple as that. it ways of dealing with it. simple as that. . ., , ways of dealing with it. simple as that. u, , . ways of dealing with it. simple as that. _, , ., ., , that. it comes at the same time as the commission _ that. it comes at the same time as the commission is _ that. it comes at the same time as the commission is telling - that. it comes at the same time as the commission is telling member| the commission is telling member states of the eu that they have got the power to stop vaccines that are

produced in the nations from being exported. what do you think of that? the who has said it is tantamount to vaccine nationalism. this the who has said it is tantamount to vaccine nationalism.— vaccine nationalism. this is the kind of language _ vaccine nationalism. this is the kind of language you _ vaccine nationalism. this is the kind of language you need - vaccine nationalism. this is the kind of language you need to l vaccine nationalism. this is the i kind of language you need to stop discussing. we are in this pandemic together and it does not recognise borders and so we have to do everything that we have in our power to find a solution, and any kind of vaccine nationalism i think is simply wrong and it would be a grave mistake and it would at the end of the day lead to the pandemic getting worse, not better. we have to work on this together. it is worse, not better. we have to work on this together.— on this together. it is quite early in the day- _ on this together. it is quite early in the day. this _ on this together. it is quite early in the day. this spat _ on this together. it is quite early in the day. this spat between i on this together. it is quite early| in the day. this spat between the on this together. it is quite early - in the day. this spat between the eu and astrazeneca has onlyjust happened, but what would be the mood in individual nation states, in their capitals, amongst governments, about how the commission has handled

this? a degree of nervousness? i think it will vary a little bit. this pandemic has many aspects, economic, social, political, not to speak about the health aspect, and i think communication is an important part of this. in this case, communication went wrong. i think the handling of the pandemic will be a little bit like the virus itself, it will mutate. you will have many different events happening, something new might pop up in a few weeks and people will forget how this is handled, but i think we need to get back on track and be serious about the distribution of the doses. because of the eu appears to have been on the back foot, in terms of the number of vaccines.— been on the back foot, in terms of the number of vaccines. yes, because first the eu — the number of vaccines. yes, because first the eu actually _ the number of vaccines. yes, because first the eu actually negotiated - first the eu actually negotiated extremely good deals with different

vaccine companies, pharmaceutical companies, and now when they are not getting them, they are getting a little upset, which i think is understandable. but we need to put this daily noise aside and think about the big picture and make sure people get vaccinated. the example i keep giving is that my mother and father—in—law in the uk, they are over 80, they were vaccinated three weeks ago. my dad who is 85, and his fiancee, 8i, weeks ago. my dad who is 85, and his fiancee, 81, are getting vaccinated next week. this is all a good move and now we need to make sure we play this by the book and get to the resource by the summer so we can put the pandemic behind us. do resource by the summer so we can put the pandemic behind us.— the pandemic behind us. do you think it was maybe — the pandemic behind us. do you think it was maybe not _ the pandemic behind us. do you think it was maybe not a _ the pandemic behind us. do you think it was maybe not a good _ the pandemic behind us. do you think it was maybe not a good idea - the pandemic behind us. do you think it was maybe not a good idea for- the pandemic behind us. do you think it was maybe not a good idea for the l it was maybe not a good idea for the commission to exist that the block acts as one instead of individually 27 countries, when it came to the vaccine? i 27 countries, when it came to the vaccine? . ., ., ., 27 countries, when it came to the vaccine? _, ., ., , .,

ramifications. last year was about getting the lockdown is right and getting the lockdown is right and getting the lockdown is right and getting the economy up and running again and now it is about the vaccinations. next time it will be about something else. i think we will see social unrest in european countries. i can't say that the last four years in the uk has been easy politically either, or the last year because of the pandemic. we will see more of this in the next few months. i do worry about the ramifications of the pandemic. you and i, normal people, we are getting frustrated with their whole situation and now it is the moment where everyone must be patient and do the right thing, which means, well, for finland it is quite easy, social distancing.

today is the anniversary of the world health organization first declaring the covid i9 outbreak a public health emergency of international concern. its director general tedros adhanom ghebreyesus has warned countries against �*vaccine nationalism', saying drugs should be prioritised for use for those most in need around the globe. vaccines are giving us another window of opportunity to bring the pandemic under control and we must not squander it. the pandemic has exposed and exploited the inequalities of our world. there is now a real danger that the very tools that could help to end of the pandemic, vaccines, may exacerbate those same inequalities. vaccine nationalism might serve short—term political goals but it is ultimately short sighted and self—defeating. we will not end the pandemic anywhere

until we end it everywhere. a man has been charged after a suspicious package was sent to a coronavirus vaccine production site in north wales. the factory in wrexham was evacuated and production of the oxford astrazeneca vaccine stopped on wednesday. police say the item was not a viable device. anthony collins from chatham in kent, has been remanded in custody to appear at maidstone crown court next month. five men have been arrested following a �*disturbance' at a former military barracks in kent being used to house hundreds of asylum seekers. kent police said a significant amount of damage was caused at the site in folkestone when a fire broke out. they are appealing for anyone with information about the incident. the barracks has been used to house around 400 asylum seekers since september. the prime minister has published an open letter to parents, saying he is "in awe" of how they are coping.

he also promises "hundreds of millions of pounds" will be spent on a national education catch up programme after the pandemic. here's our education editor branwenjeffreys. it's tough for millions of parents right now, trying to help children learn at home. schools in england are mainly closed until march. today, borisjohnson said he couldn't thank parents enough. he said they are buying time for vaccination and that is saving lives. only a few children are still learning in school. parents and teachers are worried about lost learning. there is a promise in the letter of hundreds of millions of pounds for catch—up but it's going to be a big job. one of the schools i have responsibility for, fantastic place, serves a very deprived community, only 30% of those families have access to broadband in that area. only 30%. this is digital poverty in a really extreme way and it means that many children, despite the very best efforts of schools and teachers, still cannot connect with that learning.

this warehouse is getting laptops to kids, more than 800,000 so far. but not every child will have somewhere quiet to work or parents able to give them lots of time. leading to fears that children could pay a heavy price in this pandemic. the headlines on bbc news... the eu backs down from using emergency brexit measures to restrict the movement of vaccines to northern ireland. the plan sparked outrage in london and belfast. the world health organization again warns against vaccine nationalism over the row about eu export controls. the uk prime minister publishes an open letter to parents, saying he's "in awe" of the way they're coping with home schooling. time for the sport now.

newcastle have won for the first time since the 12th december, beating everton 2—0 at goodison park. callum wilson had gone seven games without a goal, but ended his drought in style. he made the breakthrough with about 20 minutes left to go. the former bournemouth striker could have scored a hat trick, but settled for a brace. his second coming in injury time. newcastle remain sixteenth in the premier league table. i couldn't fault the way the team played, the game plan, how we went about it was terrific. the difficult few weeks but one thing that breathes a bit of confidence is a good team performance and i thought all round today was excellent. three more matches _ all round today was excellent. three more matches under— all round today was excellent. three more matches under way _ all round today was excellent. three more matches under way in - all round today was excellent. three more matches under way in the - more matches under way in the premier league. west bromwich albion taking on fulham. i9th against 18th.

month's australian open. the minister for sport in the state of victoria says that will be the daily limit for the first eight days in melbourne before being reduced to 25,000 from the quarter finals onwards. that's about 50% capacity. the tournament starts on the 8th of february. it will not be the same as the last few years but it will be the most significant international event with crowds we've seen for many months. there'll be no fans in india for england's cricket tour. they are in chennai ahead of the first test that starts on friday. ben stokes and jofra archer have trained today after being rested for the recent series in sri lanka. with most of the players in quarantine until tuesday, freshening up the squad has become more important the ecb have been really forward thinking for us as an england group to sort of rotate players in and out

of this series and i am sure at times there are frustrations because you want to see the best players on show but it's just not possible with the amount of cricket and the amount of time spent in bubbles to keep people healthy doing that. it's been a good day for england's james vince in australia, an unbeaten 98 helped sydney sixers reach the big bash league final. the holders beat perth scorchers by nine wickets. that's all the support for now. you can keep on top of the scores on the website. no more goals have gone in in the premier league. fulham still lead to 1—0 against west bromwich albion. i think theyjust hit the post. midwives are warning that confusion over coronavirus rules in maternity wards is upsetting families and in some cases staff are being verbally abused.

last month nhs england changed its guidance to say pregnant women should be able to choose someone to be with them at all stages of the maternityjourney. but an investigation by bbc news has found that isn't always possible. our health correspondent anna collinson reports: gemma, this is jacqui and jacqui, this is gemma. can i have a look at your bump? yep. aw! these two women both know what it is like to be pregnant in lockdown. gemma is due in two months. she has hardly left home since november and has gone to most appointments alone. the biggest feeling is probably anxiety at the minute. jacqui gave birth to evie last year and hopes her experiences will help gemma. you cannot control it, but then there is this huge reward at the end that is just so completely worth it. what are you doing? throughout the pandemic, the priority has always been for a woman to have a partner,

relative or friend present during labour and birth. but last month, nhs england updated its guidance to say a support person is an integral part of care and should also be able to attend scans, appointments, if the woman feels it is important, and antenatal and postnatal wards. we've spoken to more than 20 trusts and found this is not always happening, and depends on where you live. take london as an example. one trust in the east of the city allows support people on the postnatal and antenatal ward, but only at certain times. if you travel a few miles north to a second trust, they allow visiting and overnight stays. now, that is in stark contrast to a third trust we spoke to, which has currently suspended visiting, because of safety concerns. midwives say stricter rules may be in place because of local infection rates and limited space on the wards. you might have four or six

beds in a bay and so, you can imagine if you then have, on top of the six women in the bay, the six babies, you know, you have then got to think is it safe, is it possible for us to have all six partners there as well at the same time, and to be able to socially distance? we've been told by some trusts that families have been confused and in some cases, it is led to staff being abused. what is your reaction to that? that is just hugely distressing to hear. you know, these are people who have worked throughout the pandemic night and day, trying to provide the highest quality maternity care in a really frightening situation. jacqui's husband tom had to leave shortly after she gave birth. it's what gemma is most worried about. if you're on your own, you miss out on that time as a family. yeah. and itjust, yeah, worries me how i would cope with all of those emotions, as well, and not knowing what i'm doing with the baby.

yeah, i completely understand. there's so much support for you, the nhs staff, but also the other mums that are going to be there going through it with you. in terms of tom missing out on that time as a family, as soon as i came home, he took the reins and he was like "you go have a shower, go to sleep," you know, "i am fully rested and i have got this and i can take care of the baby" so that he got some one—on—one time with her as well. so this is evie. there she is. say hello. oh, look! hi! i cannot wait to have my baby and cuddle it. i suppose that is what i have to keep in mind with everything going on, just at some point, we will be home with the baby, so... do enjoy, like, the rest of your pregnancy but enjoy the birth as well, because, you know, when they get handed to you, it is literally the best feeling in the world. say bye—bye then. say bye—bye! bye!

anna collinson, bbc news. we can speak now to rachael knowles, who gave birth during the first lockdown and is now supporting dozens of other mums through social media. you had your baby in august. during the pandemic but not during lockdown. where are you still restricted in terms of bringing your partner in? restricted in terms of bringing your artner in? ~ ,,., restricted in terms of bringing your artner in? ~ , partner in? appointment wise he wasn't able _ partner in? appointment wise he wasn't able to _ partner in? appointment wise he wasn't able to come _ partner in? appointment wise he wasn't able to come into - partner in? appointment wise he wasn't able to come into any - wasn't able to come into any appointment but i was fortunate enough to have my 20 week scan just before the lockdown came in at the end of march. but it was everything that came after. i was alone for unexpected appointments. obviously you have all your planned appointments and scans but you have unplanned appointments so unfortunately we had to add a lot of unexpected scans. it was

nerve—racking. and then the birth, you go in alone and you get examined and they determine whether they can come in or not at that stage. it is quite daunting. come in or not at that stage. it is quite daunting-— come in or not at that stage. it is quite daunting. was he allowed to come in during — quite daunting. was he allowed to come in during the _ quite daunting. was he allowed to come in during the birth? - quite daunting. was he allowed to come in during the birth? he - quite daunting. was he allowed to come in during the birth? he was| come in during the birth? he was re -- come in during the birth? he was pretty -- it _ come in during the birth? he was pretty -- it was _ come in during the birth? he was pretty -- it was pretty _ come in during the birth? he was pretty -- it was pretty quick - come in during the birth? he was pretty -- it was pretty quick so i pretty —— it was pretty quick so they had to get him in quite quickly. but it is not always the case so i count myself quite lucky with how ours panned out but it has been distressing for a lot of other people. been distressing for a lot of other eo - le. ., . been distressing for a lot of other --eole. ., . , ,,, been distressing for a lot of other --eole. ., . , ., people. you are supporting other mothers or _ people. you are supporting other mothers or mothers _ people. you are supporting other mothers or mothers to _ people. you are supporting other mothers or mothers to be - people. you are supporting other mothers or mothers to be at - people. you are supporting other mothers or mothers to be at the | mothers or mothers to be at the moment through social media. what are women telling you? it is moment through social media. what are women telling you?— are women telling you? it is mixed. there is a lot _ are women telling you? it is mixed. there is a lot of _ are women telling you? it is mixed. there is a lot of frustration - there is a lot of frustration amongst people. they are nervous and worried. that is the main thing. i have clients who have a lot of unplanned visits to the hospitals due to the growth of the baby, heart
