Great Britain will not send a team to Tokyo 2020 if the spread of coronavirus continues as predicted, says British Olympic Association chairman Hugh Robertson.

"We can't see any way that this can go ahead as things are constituted," he says.

Canada has already pulled out of the Games, with the country's prime minister Justin Trudeau saying other nations should "follow their lead".

Australia has also said its athletes will prepare for a 2021 event instead, while Norway has been urged by its Olympics Committee president Berit Kjoell not to send athletes to the Games until the pandemic is under control.

"I expect we will be joining Canada and Australia shortly," added Mr Robertson.

The Olympic Games are scheduled to start on 24 July. Options include a postponement or a scaled-down version. Cancellation is "not on the agenda", the International Olympic Committee said on Sunday.

Because the coronavirus is a new respiratory virus, scientists and governments all around the world are trying to work out the best way to fight it. Vaccine development is underway but for now they say the best protection is thought to be regular and thorough handwashing.

You should also:

• Avoid contact with people who are unwell
• Catch coughs and sneezes with disposable tissue
• Throw away any used tissues and wash your hands
• Avoid touching your eyes, nose and mouth with unwashed hands

Many places are also recommending and implementing social distancing measures.

In about an hour, at 20:30 GMT, Prime Minister Boris Johnson will make a TV statement on the UK's response to the coronavirus pandemic.

It comes as MPs in Westminster continue to debate legislation to hand the government additional powers to tackle the outbreak.

The UK-wide death toll earlier hit 335.

Last week the UK foreign secretary warned against all essential travel - in other words: "Don't go overseas."

Now Dominic Raab has gone a step further saying all those Britons who are currently travelling overseas should come back.

The Foreign Office was waiting to assess how difficult it would become to travel but they have concluded there is a tight window now before borders are closed, airports are closed and flights suspended.

Some Britons are already finding it difficult to get back, so they're now saying, if you can, you should get on a commercial flight and come home.

In terms of how the government can help people abroad, it basically involves negotiation between the Foreign Office and the host government, and also other governments because others nationals are also trying to get out.

It is a question of trying to negotiate with them and say: "Can we get an exception and get one or two flights in?" Then when you do that, the actual process of negotiating slots with those airports at those times gets incredibly complicated.

You get diplomacy mixed with logistics which can get very difficult at times.

This pandemic has plunged much of our everyday life into uncertainty and it's a stressful time for people all around the world for different reasons.

If you feel like worrying about how the virus, or the constant news updates about its spread, is taking a toll on your mental health we've put together some useful tips to support your wellbeing.

In Gaza, police patrol the beachfront to check coffee shops are closed and drive around with loudspeakers ordering people to stay home after the first two coronavirus cases were announced on Sunday.

Since the start of the pandemic, health officials have worried about it reaching this impoverished coastal enclave - one of the world’s most densely populated places.

Social distancing is almost impossible among large families living in Gaza's crowded refugee camps and built-up neighbourhoods, raising fears that infection could spread fast and that overstretched hospitals could be overwhelmed.

"It’s a very difficult and challenging environment," says Gerald Rockenschaub, the head of the World Health Organization in the Palestinian Territories. He rushed to Gaza after two men returning from Pakistan tested positive for coronavirus.

"The good thing is that they were in quarantine all the time. They are isolated now so that the risk that this spreads further is minimised," Dr Rockenschaub says.

More medical supplies are being sent to Gaza, and Qatar has pledged $150m (£130m) over the coming six months to help combat the spread of Covid-19, the disease caused by the virus.

Schools, public markets and wedding halls have already been shut for two weeks. Now restrictions have been tightened.

"The number of people on the streets has dramatically decreased and so has my work," says taxi driver Alaa Saleh.

"I’m worried about having no income but I’m also worried because my job brings me into close contact with people, so maybe I could catch the virus."

Gaza has been kept under blockade by Israel and Egypt since the militant group, Hamas, took full control of the territory in 2007. Up to now, some Gazans had been commenting on the irony of how their enforced isolation appeared to be protecting them during this health crisis.

The finals of European football's biggest club competitions - the Champions League and Europa League tournaments - have been postponed because of the coronavirus outbreak, governing body Uefa has announced.

The men's and women's Champions League finals, plus the men's Europa League final, were all due to be played in May. No decision has yet been made on rearranged dates.

The Spanish domestic season has also been suspended until the government says it can be resumed without creating a health risk.

Spain has recorded 2,182 deaths from coronavirus, the government announced earlier. The number of cases registered there has increased from 28,572 on Sunday to 33,089.

Scientists currently believe that each person infected with Covid-19 infects 2.5 people over the course of around five days.

That means 30 days after that first infection, 406 people will have the virus.

But, if we reduce our exposure by half, that first infection would only have led to 15 infections in 30 days - less than 5% of 406.

Of course, it’s not guaranteed that we can reduce our exposures by half and it takes a few weeks for the effect of any intervention to show up.

But if we reduce exposure by, say, a third, the reduction is just over 85% (or 53 infections).

Look at the graphic below, which may make the maths a little clearer.

And here is our guide on self-distancing, and how to do it.

• In the last half hour, Democrats in the US Senate have again blocked a $1.8 trillion (£1.6 trillion) economic stimulus package, saying it did not do enough to help regular Americans and did not include measures to keep companies from misusing funds
• The US surgeon general has warned "this week, it’s going to get bad" while adding that too many Americans, especially young people, were not taking the pandemic seriously enough
• At least 11 states have ordered residents to stay at home; Indiana and Massachusetts were the latest to do so on Monday
• US National Guard leader Gen Joseph Lengyel described the situation as having "54 different hurricanes hitting every state" - and as of Monday morning, some 7,300 national guard troops are providing critical support nationwide

It’s now become normal to see people everywhere wearing face-masks. If you're not already wearing one you might be wondering if you should, or if they work.

The World Health Organization advises that most people don’t need masks unless they are sick.

As we reported half an hour ago, British travellers have just been ordered to return home by the UK's foreign secretary.

But many are currently stranded after the countries they are visiting closed their borders in response to the coronavirus outbreak.

Around 400 UK nationals are currently stuck in Peru, where all flights have been suspended. The Foreign Office has said rescue flights will begin this week.

Others are stranded in Guatamela, with one holidaymaker accusing the British embassy of offering him "no help".

And British tourists in Morocco needed rescue flights to return home last week.

Prime Minister Boris Johnson will talk to the country at 20:30 GMT tonight in his own words - which you can watch on BBC One and the BBC News channel.

But what has become increasingly clear this afternoon, after comments from ministers in Scotland and Northern Ireland, is the fact our leaders are willing to take further steps to enforce that so-called social distancing.

We know that politicians and many members of the public were dismayed when they saw over the weekend lots of people were just not seriously taking the advice - that simple instruction that staying at home saves lives - to heart and carrying on their lives in ways that they thought were OK.

But it is clear now politicians think they have to do more to try to enforce these rules, rather than just put them forward as advice.

So what kind of thing can we expect? Well, I think it is likely the government will tell any shops that aren't selling food or supplies that people vitally need to close.

I also think it is likely that we might see some kind of enforcement mechanism, possibly we might see the police being asked to fine people if they don't pay heed to the advice.

In a couple of hours we will know precisely what is being offered. But this is a very fast moving situation indeed.

The government has always been clear they might have to take these more draconian actions, but it is very clearly this has accelerated in a way they didn't expect just a few weeks ago.

To all of you just joining us, here's a look at the latest headlines this Monday:

• The head of the World Health Organization says the coronavirus pandemic is "accelerating"
• The number of dead in the UK has risen to 335 after a further 46 people in England died after testing positive for Covid-19
• Prime Minister Boris Johnson is to address the nation at 20:30 GMT
• British travellers urged to return home immediately
• Italy has reported another 602 deaths, bringing the total there to 6,708. The figure means the daily number of deaths has fallen for the second day in a row
• German Chancellor Angela Merkel's initial test for the new coronavirus has come back negative - she is in self-isolation after being visited by a doctor who tested positive

The BBC's political editor, Laura Kuenssberg, says Prime Minister Boris Johnson will address the nation at 20:30 GMT tonight.

This sounds like it will be different from the normal daily government briefing.

The UK's foreign secretary is calling for all British travellers to return home now while transport allows.

Last week, Dominic Raab changed travel advice for the UK to warn against all but essential travel globally for 30 days.

But in a new statement, he warns the pace at which borders are closing, airlines are suspending flights and exit bans are being enforced, there is no time to lose.

Mr Raab says: "If you are on holiday abroad the time to come home is now while you still can.”

With eggs hard to come by in UK supermarkets, poultry breeders and suppliers are seeing a huge increase in demand for hens.

Suzie Baldwin of Hollywater Hens in Hampshire says the industry has “gone mad” this month.

She has had to limit customers to three chickens each, having had people requesting up to 20 birds.

While she has refused to sell to people without the proper set up, she is concerned about what happens to all the animals when those buying them return to work once restrictions are lifted.

Howard Dobson of Poultry Paddock in Staffordshire says he sold a month’s supply of laying hens within 24 hours on Friday, a surge he puts down to people wanting a pastime while self-isolating, as well the lack of eggs in shops.

He also has had enquiries from people wanting to rear their own chickens for meat, which he says is “quite unusual”.

Liz Andreozzi of Sussex Garden Poultry says her phone has not stopped ringing, despite having sold out of her month’s supply last week.

She too is “hugely concerned” about the hens’ welfare and is now looking to put in place social-distancing measures to keep herself and customers safe for any future sales.

The death toll is finally starting to drop in Italy, the new epicentre of the coronavirus pandemic. But how did the outbreak begin?

Scientists believe the virus originated in infected animals at a seafood and wildlife market in the Chinese city of Wuhan, where it crossed the species barrier.

We still don’t know exactly how it began, but one possible scenario is that a bat left a trace of coronavirus in its droppings and a wild animal picked up the infection from the excrement, allowing it to circulate in wildlife and eventually be passed onto humans.

More than 70% of emerging infections in humans are estimated to have come from animals - particularly wild ones.

The virus is then thought to have spread among humans through droplets from the nose or mouth, or by people coming into contact with contaminated surfaces or skin.

As people travelled around the world, it was brought to new countries, and as it is a new strain of coronavirus there is not yet any vaccine against it.

You can read more about the links between wildlife and diseases here.

Italy has reported another 602 deaths from coronavirus, Reuters news agency says. That brings the total death toll up to 6,078 - but it means that the daily number of deaths has fallen for the second day in a row, down from 651 on Sunday.

Crucially, our Rome correspondent Mark Lowen says, the rise in new infections has slowed again, from 9 to 8.1%.

UK Health Secretary Matt Hancock says a total of 7,563 retired clinicians have answered the government's call to return to work in the NHS.

The emergency bill currently being debated by MPs gives powers to re-register workers such as nurses, midwives, paramedics and social workers.

"I want to pay tribute to every single one of them," Mr Hancock said.
