Baroness Daido Harding, the woman in charge of it, says the system is functioning, but it's not yet a gold stay at Standard Service.

Anyone who tests positive for Covert 19 is now asked to give details of people they've spent more than 50 minutes with less than two meters apart.

Those people are then contacted and told herself.

Isolate for a fortnight.

The new system is seen as a vital tool to control local spikes in infection.

The first NHS figures show that just over 8000 people who tested positive in a week were then referred to the contact tracing system.

2/3 of them were contacted, but more than 2.5 1000 people who had tested positive couldn't be reached.

Traces working for the new service did track down almost 32,000 people who had been in close contact with those who had the virus.

They spoke to 85% of them and told them to self isolate.

But again, a large number of names given couldn't be reached.

Almost 5000 His our health editor Hugh Pin.

If you test positive NHS test and trace will contact you to trace people, you might have infected.

Testing and tracing is vital to prevent future Corona virus outbreaks.

Developing a new system for England was launched two weeks ago.

Now we have some details of how it's working in the first week.

2/3 of those testing positive handed over details of people they'd recently been in contact with.

Save lives.

Are you a bit concerns that with 1/3 of people who tested positive, for whatever reason, you couldn't get details of recent contacts?

I think that the system has worked well on to get 2/3 in the first week of operation.

It beat my expectations.

Onda then toe have the vast majority 85% of the contacts that were given self isolating that beat my expectations to on this system gets better and better.

Here's how contact tracing should work.

If I test positive for the virus, I'd be contacted by officials by phone or email on asked who I'd met up with in recent days, and that means meetings at less than two meters face to face, not someone I might have bumped into in a shop that might include, for example, friends.

I'd spent time with Andi work colleagues I might have bean in meetings with or a wider circle off recent contacts.

All that would then be assessed by a clinical team on those people might be contacted and told to self isolate.

For 14 days, testing is carried out a drive thru centers that locations visited by mobile teams and in hospitals and care homes.

Home test kits are sent out.

Then information on those testing positive is sent to health officials who find out more about the contacts.

One of them is Josi.

She's working from home in Red Car.

Everybody that I've spoke to has been more than happy to share the information that we need, and at the moment I've only had people that have had a couple of contacts are you know, a handful.

But I guess once, um, flocked, measures ease that maybe we will see and more contacts.

Then the traces have to follow up the contacts.

Some who wished to remain anonymous have told us they've had very little work to do.

It's not right that you paid to do nothing.

I think the time could be better spent.

There's mass confusion about system and about what to do.

What advice to give to say its world beating is big joke.

In a similar system in Scotland, there's an average of 1.5 contacts traced for each case.

Northern Ireland, with the first to be launched in the UK and Wales, also have testing and tracing programs.

The authorities in England say the system works, but it's early days on.

There's more to do to reach your wider public.

Cubin.

BBC news businesses across Britain, according for the two meters social distancing rule to be relaxed and reduced to just one meter to help the economy recover and allow more schools to reopen.

Downing Street says it's being kept under review.

Our business editor, Simon Jack, looks at the difference.

It could make morning coffee at the Black Do Cafe in tring Heart Future comes with a complimentary and compulsory temperature check.

That's Sasha.

Leak started the cafe four years ago and has been surviving on take aways, opening just three days a week.

She would love to welcome her loyal customers back inside but can't see it happening.

People would come in here, virtually sit on each other's laps.

You know, the whole thrill was being able to get seeing here.

We'd have, like, 12 staff working.

All of that has to change.

It's scary because we don't know, really, If we can't put people in here, um, we're not gonna get revenue.

We can't were not gonna survive.

Hi, Peter.

Hi.

Thank you.

100 yards away, Peter.

Book Neil showed with the alterations he's made to one of his 28 pubs.

He has 1000 staff which reduces capacity, presumably 950 Autumn on furlough.

He's convinced he is ready to reopen, but fears many others may never.

If the two meter rule isn't relaxed, I would estimate that if two meters was in place, that huge number of pups will never, ever, ever reopen for us, it would mean that way built open some, but it be some economic.

We really need it to get nearer meter for it to make any kind of sense.

Now the difference between two meters and well meter.

It may not sound like a lot, but for the hospitality industry.

In particular, it's huge.

A two meters distance, the venue is operating at an estimated 30% of capacity.

In other words, it's losing money one meter closer and it can operate and around 70% of capacity.

You got a chance of breaking even.

That distance could be the difference between survival and going bust, and hundreds of thousands of jobs depend on it.

But what about the health implications of relaxing the two meter rule?

Germany applies a 1.5 meter standard.

Annoyance.

Sweden.

It's just a meter.

Are we risking jobs by playing it too safe?

Linda Bold is a professor of public health at Edinburgh University.

If you have 100 people in a room in terms of the risk of infection, depending on the assessing, it would be around 13 people.

For example, who might be infected if you're within one research.

If you go beyond that, for example, Jimmy 2.5 it reduces a lot to run three people actually on.

Then, if you go over two meters, it reduces again by 50% to just over one person.

The government's target date for easing restrictions on the hospitality industry is July the fourth.

But relaxing the two meter rule will be more than the icing on the cake.

Without that, there may be no cake.

A tall Simon Jack.

BBC NEWS There are more implications for businesses emerging tonight.

Checks on goods coming into the UK from the EU next year could be much less rigorous than planned.

It's understood that the impact off the Corona virus means the government may need to take a more flexible approach.

While our political correspond.

Chris Mason is out.

Westminster, what more can you tell us?

Well, Brexit might have gone quiet, but it has not gone away.

You'll remember that we formally left the European Union at the end of January.

We are in this transition period where technically, yes, we're outside the EU, but in pretty much all practical terms, we are still in, and we're in a transition period that runs until the end of this year.

Now the government is likely to confirm formally very soon that that transition period will not be extended.

That's what they've been saying repeatedly for the last few months.

But the reports in the Financial Times tonight saying that they will change their approach to imports coming into the country immediately after the end of the transition period at the start of next year.

They will have a more flexible, pragmatic approach in a source confirming that tonight, saying to the BBC that that is essential given the impact of the Corona viruses.

Businesses adjust to the reality after the virus but also being outside of the single market and the Customs union, two of those big economic structures off the European Union.

You might have thought you'd heard the last of Brexit.

You haven't Chris Mason in Westminster.

Thank you.
