The Cabinet office minister, Michael Gove, blamed a global shortage of chemicals needed for the test.

Tonight it emerged that a 13 year old boy from Brixton in south London has died from the virus, Britain's youngest victims.

So far.

Today's figures show that a total of 1789 people have died in the UK with Corona virus.

That's an increase of 381 since yesterday.

On the biggest rise so far.

Almost all of them had underlying health conditions are health editor Hugh Pin reports.

Drive through Corona Virus testing for some NHS staff has begun in England, but this is a very limited trial.

It's not clear how quickly it can be expanded elsewhere.

Tests on patients are analysed in hospital on public health laboratories like this.

They're based on swab samples.

NHS staff are frustrated, they can't be tested, which means they can't find out whether it's safe to return to work.

Hospitals in England have now been told to test key workers if they can.

On what we've seen is what doctors like Jenna Do who is a consultant, say a lack of testing keep staff away from work just when they most needed in a week or teams time.

We've seen the way around because they had grown cold.

Well, something else really testing even with the imperfect nature of those tests as they become ready honey Willful healthcare professionals I raised the issue at today's Downing Street press conference.

Many NHS staff are saying that testing for them is not obviously available in their places of work now or somewhere accessible.

Even after pledges made by officials and ministers in recent weeks, it was a priority.

What do you say to them?

Well, you we want to increase the number of tests.

We are increasing the number of tests I mentioned earlier that one of the constraints on our capacity to increase testing overall is supply of thes specific free agents that specific chemicals that are needed in order to make sure that tests are reliable.

It's also the case, as I'm sure you're aware that we've been working with the private sector on with academics on boots, for example, have increased the number off drive in centers for NHS from front line workers to be tested, the first acknowledgment there of problems getting raw materials for more testing.

The Welsh government started testing NHS staff earlier this month.

Scotland and Northern Ireland have no followed.

The number of people tested in the UK rose rapidly after lab capacity was expanded.

It was above 8000 couple of days ago but has slipped back a little.

So how does that compare with other countries?

This graph shows the number of tests per 100,000 people since the first Corona virus death in each country.

South Korea, with extensive testing regime, is well ahead of the UK and the US A 13 year old boy who tested positive for the virus has died at King's College Hospital in London.

The trust said thoughts and condolences were with his family.

It's not known if he had an underlying health condition.

I am Karen, who's pregnant, was in hospital with Cove in 19 and pneumonia.

She was very ill and said she was fighting for her baby.

She is now recovering.

I'm very lucky.

I'm so grateful to be home to see my family.

And now it's just a case off waiting and saying How my babies, there's no one knows know what's going to know Harry is or if he's okay for sure.

Known to his health, Stewart is also recovering.

No, he says.

Being hit by the virus was terrifying.

My lungs.

We're losing function as it is that we're really struggling with the disease in them.

Andi, I really had to call you put alot my reserves and prayers that are more in detail and it was really a question, I think fundamentally Do you want to live?

The prime minister chaired a Cabinet meeting by video link.

He and two colleagues are self isolating because of symptoms.

He told them the situation is going to get worse before it gets better, but it will get better.

Well, Hugh is with me now.

Why is it proving so difficult to ramp up the testing?

Well, Sophie does seem a bit strange.

I mean, first of all, the 25,000 today target for testing we told won't happen to a late April.

A bit later than we thought.

Currently it's round about 8000 so there's a lot of time to make up on that.

But the capacity were also told off labs to carry out these tests is round about 12,000.

Now we'll go up to 15,000 by the end of the week, so there is a gap and I think there's some frustration amongst ministers.

Michael Go.

We heard saying that needs to be a lot more done to make it all go faster.

And I think tomorrow we're going to hear of a new drive to get Mawr NHS staff tested using that extra capacity, and in the meantime, we heard more about how the virus is spreading in the UK Yes, in the Downing Street press conference of some charts shown, here's one of them on the number of new cases reported each day across the UK, and you could see that daily number going up quite sharply in the middle of March.

Then it reaches a sort of plateau in the last few days, although the latest number has gone up a little bit further, and that, I think, is the a green shoot that was being referred to by NHS England today, although Steve Paris, the medical director, said.

We weren't out of the woods by any means.

Another chart showed hospital admissions rising pretty rapidly in England up above 9000 now London rising faster than other regions.

Although the northwest and southeast of England.

I had also seen a bit of a pick up, a reminder that whether or not there are green shoots, there's going to be an awful lot of pressure on the NHS and hospitals in the next few weeks.

Thank you.

One of Britain's most senior police officers has admitted that mistakes have been made by officers in their enforcement of the new emergency powers.

Critics say some tactics have been heavy handed.

Last week, Darvish a police came in for criticism after using drones to film people walking in the Peak district.

They then posted the footage on social media.

Our home affairs correspondent Daniel Sandford reports.

That's what is normally a busy station in east London.

You shouldn't be traveling.

That's the advice from the government.

British transport police asking passengers why they are traveling.

You shouldn't right, So my advice is to go back home using three of the four means engaging, explaining the new laws, encouraging trying to avoid the fourth enforcement through fines on all the time, allowing essential workers through.

With such drastic laws having come in so quickly, it has inevitably led to different police forces interpreting them differently.

And that has led to tensions behind the scenes.

As chief constables tried to work out a common approach, Lancaster police has already issued more than 100 fines.

The U.

K's largest force, the Metropolitan Police, has issued none.

The head of the national police chief's council agreed that there needs to be more consistency.

We're bringing in new roles that have never been in existence before on we're having to learn as we go along.

And I think people ought to accept that mistakes will be made as we work our way through that.

The law says that people can only leave home for basic necessities for medical needs for essential work, or to exercise once per day, and police can issue on the spot fines if people have no reasonable excuse to be away from home or for any social gathering of more than two people, not from the same household.

But Darvish polices decision to use drones and social media videos to shame people exercising in the peak district has worried others in policing.

When I saw it on the television on, I saw the footage.

I have to say that it was a bit of a face palm moment for May I because I feared that the kind of criticism that that that the uninsured But today the chief constable of Darvish her defended the decision purpose of putting the video up waas the weekend after it had a nice where there where?

Frankly, the peak district was completely inundated with visitors from across the whole country, putting some very, very vulnerable communities at risk and stretching emergency services.

But in this upside down world, where park benches a taped off for public safety and people are asked to exercise away from each other, the growing consensus among police chiefs and police and crime commissioners is that some of the strongest laws ever introduced in this country need to be used wisely and not overzealously.
