evening. officials in charge of the coronavirus testing network have apologised after increasing evidence that the system is struggling to meet demand, with some people being asked to travel hundreds of miles to get tested. laboratories in the uk have been described as maxed out, with 170,000 tests a day. baroness harding, head of nhs test and trace in england, said she was very sorry for the situation but that the vast majority could still get appointments in their own regions. earlier this evening, the uk government said that from tomorrow no—one will have to travel more than 75 miles for a test, as our health editor, hugh pym, reports. test results delivered in just a couple of hours using technology like this. that's what the government wants to see delivered on a large scale, making regular checks possible for millions of people. there's more funding for trials, but it's a long—term goal. right now, there are complaints from some people about being sent long distances to get tested, including one family who requested tests at their local site at glasgow airport. stephen, who didn't want to give his full name, said he was offered belfast when he tried to book online. belfast wasn't exactly desirable, especially with a ferry trip. so i went back in again to try it again, and the second time it tried to send me to portree in the isle of skye, which is 127 miles and a five and a half hour round trip, well, five and a half hours each way. stephen and his family did eventually get tests locally, although there was a long wait at the site. this lab in glasgow analysing swabs is run by the uk government. the test and protect scheme is managed by nhs scotland. a postcode search of coronavirus test booking revealed more examples, including people with symptoms in totnes in devon being directed to carmarthen, nearly 200 miles away. one in penrith advised to go to dumfries, trip of more than 50 miles. in london, in one instance, advice to go advice to go to a centre in cardiff, a three hour drive of 150 miles. and for a suffolk man, an even longer proposed journey. i went through the process, and it came back with availability for testing in a place on the outskirts of blackburn, which is over 250 miles away. so i was convinced i'd got it wrong, cancelled, re—processed, and i got exactly the same answer. officials say the system will now be adjusted to reduce these driving times. ministers argue that resources have to be focused on local outbreaks and in some other areas there may be longer waits. the vast majority get it quickly and close to home, but when those testing centres are full, then obviously people are offered a test at the nearest place at which one is available. and we have got, you know, we have got a significant demand for testing, but we have also got a very high capacity. but official figures suggest there is more capacity at big labs than the number of tests carried out, and some experts want to know what's really happening. there should not be a problem with people getting test results, but there is, so something's not quite right. those figures don't seem to add up, and that is our main concern. the government says developing saliva tests with rapid results could have a big impact on curbing the virus but that'll take time. right now, there are other urgent testing issues to address. and hugh is here. it isa it is a challenging time, hugh, schools and universities returning, people returning to work in many areas. what is your sense of where this testing capacity is going? well, huw, it is certainly a time when experts say you need a testing system that is up and running and fit for purpose. clearly, there are capacity issues, ministers are acknowledging that. demand has gone up acknowledging that. demand has gone up very rapidly sincejune, but the ability to process has not kept up, and there has been an apology for some of the issues we've highlighted, people being offered these tests some way from home. but ministers are clear this is a small minority, they say capacity is going to be built up further, with the new lab coming on stream in the east midlands, they have this longer term plan for mass testing involving rapid results from saliva tests, which will be much easier for people to handle. they say that will make a big difference, it is a long—term goal. right now there clearly is an issue, and an example of the challenge that they are facing around the uk is in scotland, where the r number, anything above one shows the virus is accelerating, that has gone up, the top of the range may now be 1.4 according to the first minister. that shows just how much of a potential threat to the virus still poses right around the virus still poses right around the uk. hugh, many thanks, hugh pym, our health editor. the latest government figures show there were 1,735 new confirmed cases of coronavirus across the uk in the latest 24—hour period. that means the average number of new cases reported per day in the last week was 1,435. 13 deaths were also reported. that's those who have died within 28 days of a positive covid—19 test. that means, on average in the past week, seven deaths were announced every day. that takes the total number across the uk to 41,527. people arriving in wales and scotland from portugal must now self—isolate for 14 days, but the rules covering england and northern ireland have not changed. the rules for wales apply from four o'clock tomorrow morning, while in scotland they begin 24 hours later on saturday morning. cases of coronavirus in portugal have been rising in the past week. some of the biggest names in british aviation have accused the uk government of a lack of leadership, and they're calling on ministers to approve coronavirus tests at airports to give people the confidence to travel, as our transport correspondent tom burridge reports. people were heading out to greece from edinburgh this afternoon, even though they'll have to quarantine when home. i work from home, i can self—isolate for 14 days, and i'm totally happy to do that. i got to have a big operation when i'm back home, so we really wanted to go on the holiday. but people in greece now who live in scotland aren't so happy. i'm flying back to glasgow, it has an infection rate of 21, i believe. i'm coming from a country with an infection rate of 15, so i'm going from a country with a lower rate than the one i'm going back to, yet i have to isolate. but the welsh government has decided that zakynthos and five other greek islands pose a risk. people in wales will only have to self—isolate if they return from this part of the country. there is still no quarantine for the whole of greece if you live in england or northern ireland. it's really quiet at heathrow right now, but aviation bosses say the government could change that by bringing in testing for covid at airports. but the facility already built at heathrow isn't being used because it doesn't have the government's backing. a passenger arriving into the uk will have booked a test online, they would then provide a saliva swab test to a trained nurse. they should get the results of that test within 24 hours, and they would be given a kit so they could do a second test at home in several days. two negative results would cut your quarantine period short. the uk government says tests can give false results, but the boss of this airline says it has to happen. quite frankly, i think at this moment in time the uk government is overseeing the demise of the aviation industry in the uk. we are seeing more job losses than we did in the demise of the coal industry in the ‘80s. that surely cannot be an accolade any government would like to have. portugal's infection rate has risen beyond the uk government's benchmark, but tonight a surprise — it will not be added to the quarantine list for england. some had already changed their holiday plans. we heard when we were at the beginning of the week that possibly portugal would go back, and so we had one friend who absolutely could not risk having to go into quarantine, and she had to buy a very expensive flight and left this morning. but the welsh and scottish governments are adding mainland portugal to the quarantine list. working out who has to self—isolate after a trip abroad isn't a relaxing affair. tom burridge, bbc news. at southwark crown court, a convicted sex offender has been jailed for life for the murder of two women whose bodies were found in a freezer at his home. the remains were discovered at zahid younis's flat in east london in april last year. younis refused to appear in the dock for sentencing. the judge at southwark crown court called him a heartless narcissist and said he should serve a minimum of 38 years, as our correspondent danny shaw reports. hello, police! police officer, make yourself known! this is the moment police make a grim discovery. hello, police. they are searching for zahid younis at his flat in canning town. he had been reported missing. there's a freezer here that i want to get into. it's locked but... officers are suspicious about a locked freezer with flies around it, but when they force it open with a crowbar, it isn't younis they find. inside the freezer were the remains of two women zahid younis had murdered. one body had been stored there for almost two and a half years, the other for nearly 12 months. both victims had suffered terrible injuries, including fractures to their ribs. one of the women was henriett szucs, originally from hungary. she wrote about her relationship with younis, who was controlling and abusive. the second victim was mother of three mihrican mustafa, also known as m] orjan. both women were in their 30s when they died. don't listen to any rubbish he said. once he's out, whatever age he is, watch out, watch out, because he ain't going to stop. he's a monster. yeah. and people be aware there are people like that out there. and i think... watch your daughters. zahid younis had an appalling record of violence and sexual abuse. during an islamic ceremony, he illegally married a 14—year—old girl. she then became pregnant. younis was sent to prison and had to register as a sex offender. within months of release, he brutally beat a 17—year—old girl, breaking her arm in three places, and was jailed again. but domestic violence campaigners say police should have been more alert to the dangers younis posed and helped safeguard the women. on one occasion, officers visited him, unaware one of the victims lay dead in his flat. it sends a very important and strong message to the authorities that they should understand these cases of domestic abuse much more fully and recognise the risks that individuals pose and the chances of ongoing perpetrating of violence and be sure to monitor and check those individuals more frequently. there are now calls for a review of the case to find out if the murders of mihrican and henriett could have been prevented. danny shaw, bbc news, at canning town in east london. more than 40% of all migrants who claimed asylum in the second three months of this year arrived by small boats from france. that's according to the newly appointed clandestine channel threat commander, dan o'mahoney, who gave evidence to the home affairs commitee of mps today. yesterday a record number of migrants, 416, made the crossing from france to the uk. costa coffee says it could lose up to 1,650 jobs as it restructures its business to deal with the downturn in sales since the coronavirus outbreak. costa, which is owned by coca—cola, says it plans to remove the role of assistant manager from its stores and can't be sure when trading will improve. the online retail giant amazon says it will create a further 7,000 jobs in the uk this year to meet growing demand. it means the company will have 40,000 workers based here and comes as online sales have seen huge growth during the pandemic. our business editor, simon jack, is here. i mentioned coronavirus, is that the main factor? it is massive factor, amazon was growing very fast, earlier this year, it added 3,000 permanentjobs earlier this year, it added 3,000 permanent jobs and that earlier this year, it added 3,000 permanentjobs and that was before lockdown, then the pandemic hit, surge in online shopping and they took on thousands of temporary staff. they think like other, that that shift is permanent. hence, the 7,000 permanent new role, if you look at the growth in their permanent head count it has been remarkable. in 201510,000. 202040,000. remarkable. in 201510,000. 202040 , 000. that is remarkable. in 201510,000. 202040,000. that is mirrored by their sales which have gone from 7 billion in 2015 to 17 billion now, so billion in 2015 to 17 billion now, so it is massive success, the jobs are welcome, we have spoken about lots of job losses are welcome, we have spoken about lots ofjob losses but the rise and rise of amazon, the flip side of thatis rise of amazon, the flip side of that is the decline and fall of other retail stores, and if you look across the industry, you will see over that same period, 106,000 fewer jobs in retail. i would add another 20,000 because the numbers are only to march. amazon criticised in some cases for its working practise, their say they are addressing that, and tax, a last year they paid 220 million on 13 billion of sales, most in employee income tax, although sales are 13 billion they operate with almost zero profit margins and as these numbers suggest and their competitors know that is very hard to compete against. thank you simon. thank you simon. researchers have found that children with coronavirus infection may display a very wide range of symptoms. people can request a test if they have a new continuous cough, fever or loss of taste or smell, but research by queen's university belfast found that diarrhoea and vomiting were more common symptoms in children with covid—19. our medical editor fergus walsh has the latest. education unlocked, as more and more schools open their gates. whilst coronavirus poses very little risk to children's health, it is important to avoid outbreaks spreading in schools. so this raises the question, how to spot the infection in the young. at present, you can get a coronavirus test if you display any of the following symptoms. a high temperature, a new, continuous cough, or a loss of taste or smell. researchers, though, have found that in children, a huge variety of other symptoms may indicate a covid—19 infection. these include headache, fatigue, sore throat, loss of appetite, skin rashes, diarrhoea and vomiting. the trouble is, these can also apply to a whole range of other ailments. researchers in belfast believe the testing criteria for children need to be widened. based on the data that we found, i think that gastrointestinal symptoms like diarrhoea and vomiting in particular should be added to the testing strategy for children. i think we can reassure families that symptoms such as a sniffly nose, so sneezing or a blocked nose, are not associated with covid—19 and those children should not need a test. hand hygiene, face masks and year group bubbles will help minimise the risk of coronavirus spreading. but if children are under the weather, what will parents do?
