NHS worker makes emotional 'stay at home' plea
An NHS worker's emotional plea for people to stay at home has been shared thousands of times.
In an emotional video, Chanice Cushion says she will leave her family home to protect her mother-in-law who has an underlying condition.
"I really thought I could put across to people you really need to stay indoors - this is serious," she tells the BBC.
UK PM defers to the experts on outbreak measures
Helen Catt
Political correspondent
There have been legitimate questions put to the government around whether measures should have been put in place sooner to stop the spread of this virus.
The government has consistently said it is doing the right thing at the right time based on scientific evidence, and what we saw in this press conference was the prime minister deferring to the experts.
Obviously, the UK strategy has been different from what we have seen in other countries, so that has raised questions about how the government is choosing to deal with it.
But coronavirus is an unknown - a new virus where people don't really know what happens with it, and it can only ever be a best guess.
However, it is up to the government to explain why their best guess relates to certain actions they are taking - and certain actions they are not.

What happened at the latest UK press conference?
Boris Johnson’s latest press briefing on the UK’s response to the coronavirus pandemic has come to an end. Here’s what happened:
BreakingBritish diplomat, 37, dies of coronavirus
A British diplomat has died in Hungary after contracting coronavirus.
Steven Dick, the deputy ambassador in the capital, Budapest, was aged 37.
Mr Dick, an Arabic speaker who had worked for some years in Kabul and Riyadh, took up his post in Hungary last year.
It is not known if he had any underlying medical conditions.
UK Foreign Secretary Dominic Raab said: "I am desperately saddened by the news of Steven’s death and my heart goes out to his parents Steven and Carol.
"Steven was a dedicated diplomat and represented his country with great skill and passion. He will be missed by all those who knew him and worked with him."
UK PM says NHS volunteer army 'the size of Coventry'
Firms should stop profiteering, says PM
In response to a question about his strategy, Boris Johnson says the UK will follow scientific advice not "political diktat".
Asked about firms profiteering during the crisis, he says firms should not be "exploiting" the needs of the public at a time of "national emergency".
He says the government is "looking very carefully" at what it "may be necessary to do" using the law to stop profiteering, "as in wartime".
Whitty: Tests won't be available online next week
There has been talk of antibody tests being available to buy online. These tests would allow people to see if they have been infected - meaning they should then be immune.
Chief medical officer Chris Whitty says: “Once we are confident of which tests work… there is a hierarchy of things we need to do.”
First, experts will need to assess what proportion of people get coronavirus without any syptoms, he says.
Then it will be a case of testing NHS workers to “work out who is immune to this infection and who isn’t”, then moving from there to others.
But Prof Whitty adds: “I do not think this is something we will suddenly be ordering online for next week."
Johnson: More tricky to help self-employed
Boris Johnson again faces pressure to do something to help the self-employed.
The PM says the government has “moved with extraordinary speed to support and prop up the whole of the economy of this country, putting our arms around workers of all kinds to the best extent we possibly can”.
He admits it was “easiest” to help employees and more “tricky” to work out a package for the self-employed.
“But that has been done at incredible speed,” adds the PM, promising that Chancellor Rishi Sunak will make an announcement on the plan tomorrow.
He adds: “I don't think there has been a time in our history in the last century that a government of this country has put its arms around so many people to get through such a tough time.”
Mr Johnson concludes the press conference saying: “We will beat this and we will beat this together, and we will do it by protecting our NHS and staying at home. That is how we will save lives."
Johnson: Employers should protect you
The PM is asked if more lives could be saved if he stopped more people going to work.
Mr Johnson says he wants to "repeat the basic message, if you can stay at home then you overwhelmingly should".
But he says for those who have to go to work, it is "vital" for employers to follow rules on social distancing and "ensure" the necessary protection.
Chief Medical Officer Chris Whitty says every country is approaching this “slightly differently and has a slightly different epidemic pattern”.
But he says the modelling in the UK was “based on the idea quite a lot of people would have to go to work”.
However, he adds that people should avoid anything that is “discretionary”.
We've ordered huge numbers of tests, says UK PM
There's a question about how long it will be before NHS staff will get greater access to coronavirus tests.
In reply, Boris Johnson says the UK is ordering "huge numbers of tests". He says UK-wide testing should hit 250,000 "very soon".
Prof Chris Whitty, the UK government's chief medical adviser, says the UK has to face the "practical reality" that other countries want the components as well.
The prime minister says the UK has done more tests than "most" European countries.
'We don't know UK-wide infection rate'
Sir Patrick Vallance, the UK government’s chief scientific adviser, is asked about a recent Oxford University study which said as much as 50% of the UK population may have been exposed to the virus.
He says that they "don't know" yet how many people in the UK have had the virus, which is why more testing is vital.
Whitty: Antibody virus test 'quite close'
Boris Johnson defends the government's programme to support businesses, calling it "unprecedented".
He says the country is "coping very well indeed" under challenging circumstances.
Asked about the rate of testing in the UK, Prof Chris Whitty, the UK government’s chief medical adviser, says testing of people to determine whether they have the virus is being "ramped up".
He says an antibody test - to see whether people have had it - is "quite close", but has not yet finished being evaluated.
Sir Patrick Vallance, the UK government’s chief scientific adviser, says testing is "crucial" and the UK needs to do more of it.
BreakingItaly sees slight fall in new cases
Away from the UK, Italy has reported another 683 deaths in the past 24 hours. That is a slight fall from Tuesday's 743 deaths, but it brings to 7,503 the number of people who have died in Italy since the outbreak there began.
There has also been a slight drop in the number of new cases. Italy has 57,521 current cases, a rise of 3,491 in the past 24 hours. On Tuesday the recorded increase was 3,612.
Details are normally given by Italy's head of civil protection, Angelo Borrelli, but he has a mild fever.
Johnson: Core policy is to stay at home
Boris Johnson says any "world class health service has only limited numbers of doctors, nurses and specialist equipment", so the more people who become sick at any one time, the harder it is for the NHS to cope.
"It is vital to delay the spread," he adds. "And with your help we will slow the spread of the disease."
The PM thanks "everyone who has been following the clear rules set out on Monday", along with frontline NHS staff and public services.
He also praises all those who have volunteered to help the NHS - a number, he says, equivalent to the population of Coventry.
Mr Johnson concludes by repeating the government's "core policy" - "stay at home, protect the NHS and save lives".
UK PM begins coronavirus press briefing
Boris Johnson kicks off the press conference, repeating that the government will take "the right measures at the right time".
He says the NHS, like other health services, only has a limited amount of equipment so it is vital to delay the spread of the virus.
Hope amid the coronavirus chaos
We are expecting Boris Johnson to start his press conference any moment now.
He will be joined by the UK's chief medical officer Prof Chris Whitty and chief scientific officer Sir Patrick Vallance.
In the meantime, take a look at our five reasons to find hope amid the chaos caused by the outbreak.
Work begins on London's makeshift field hospital
Work is under way to boost NHS capacity by turning London's ExCel Centre in the Docklands into a makeshift field hospital capable of serving up to 4,000 patients.
NHS medics will treat coronavirus patients at the facility, which will be known as the Nightingale Hospital.
It will initially provide about 500 beds equipped with ventilators and oxygen.
