Schools across the UK are set to close as early as Friday, in the latest attempt to curb the spread of coronavirus. In other UK news, Boris Johnson has promised the government will protect private renters after its £350bn coronavirus relief package was criticised for omitting them, and will also discuss the idea of a universal basic income with opposition parties.
Under further government plans police will have the power to detain people infected with coronavirus as efforts to tackle Covid-19 ramp up. Schools in Scotland and Wales are set to shut by the end of the week, while British supermarkets have begun rationing more products after shelves were picked clean by stockpilers.
Elsewhere, the virus has now been detected in all 50 US states, with the death toll passing 100; Donald Trump’s administration has said it will increase the availability of testing and urged all Americans to take steps to avoid infection. Global infections have now passed 200,000, according to Johns Hopkins University. Some 8,000 people have died and 82,000 have recovered.

A coronavirus test that reveals who has had Covid-19 but not shown symptoms has been hailed as a "game-changer".
The Government's chief scientific adviser Sir Patrick Vallance said Public Health England's (PHE) work on the antibody test is "progressing very fast", and will provide valuable insight into the pandemic.
Speaking at the daily Downing Street press conference, Prime Minister Boris Johnson said development of the test was not far away.
"The great thing about having a test to see whether you've had it enough, is suddenly a green light goes on above your head and you can go back to work safe and confident in the knowledge that you are most unlikely to get it again.", he said.
"So for an economic point of view, from a social point of view, it really could be a game-changer. You can really see the potential of that advance, which, as I say, is coming down the track."
Italy mulls outdoor exercise ban as deaths soar
The Italian government threatened to ban all outdoor exercise as the coronavirus death toll soared to 2,978 and frustration grew over the number of people defying the nation's lockdown.
Italy was the first Western country to impose severe restrictions on movement to contain the illness. But a week after the curbs were imposed, the disease is still spreading and hospitals in the north are at breaking point.
The northern region of Lombardy, on the frontline of the battle against the pandemic, has asked recently retired health workers to return to work and help colleagues overwhelmed by the crisis.
"I make a heartfelt appeal to all the doctors, nurses and medical personnel who have retired in the last two years...to help us in this emergency," regional Governor Attilio Fontana told a news conference.
Asked to comment on restrictions like those reported to be coming to the capital, Boris Johnson refused to rule anything out - even limiting when, where and how people travel around.
The PM said: "We live in a land of liberty as you know, and it's one of the great features of our lives that we don't tend to impose those sorts of restrictions on people in this country.
"But I have to tell you we will rule nothing out and we will certainly wish to consider bringing forward further and faster measures where that is necessary to suppress the peak of the epidemic to protect our NHS, to minimise casualties, and to minimise suffering."
"The Prime Minister is right to announce school closures to stop the spread of this virus", he said.

"Not even at the height of the Theresa May/Jeremy Corbyn years have the green benches been so empty for prime minister’s questions" Tom Peck writes.
