Newspaper headlines: 24 hours to avoid complete lockdown, PM warns
Several of the newspapers have pictures of crowds taking advantage of the spring sunshine to get outdoors - in spite of the guidelines on social distancing.
"Madness" is the Daily Mirror's headline.
The Daily Telegraph says there's been deep concern within Whitehall as it emerged over the weekend that public messages urging people to stay at home and avoid socialising were apparently being ignored.
According to the Times, Prime Minister Boris Johnson is facing calls from his cabinet and senior advisers to impose a full lockdown in London.
A senior government source tells the paper: "It is inevitable - you just have to look at other countries."
Buzzfeed News says the prime minister faces a "full scale mutiny" from his cabinet and senior aides if he doesn't enforce a lockdown of London in the next 24 hours.
It adds that Mr Johnson has deep ideological reservations about turning Britain into an effective police state.
Some Americans also appear to have been flouting guidelines on close contact with others.
The New York Times says the governor, Andrew Cuomo, went out of his way to criticise the behaviour of some residents, describing it as insensitive and arrogant.
The Los Angeles Times reports that California's sweeping stay-at-home order resulted in a weekend like no other, with people staying indoors and, when outside, keeping at least six feet apart.
But there were exceptions, it adds - with crowds gathering on beaches.
Most sports pages lead with the admission by the International Olympic Committee that the Tokyo Games may have to be postponed.
The Financial Times, on its front page, reports that talks between Olympics and Japanese officials in recent days have focused on the length of a delay.
The likely new date is the summer of 2021, although other options include the autumn of next year and even pushing the Games to 2022, the paper adds.
With churches now closed, the Times says yesterday was a day of virtual vicars taking to the internet to preach to their congregations.
At home, people joined in the prayers, sent each other uplifting messages or just watched from the comfort of their beds.
The Mail says that at St Martin-in-the-Fields, in Central London, more than 1,000 people have been joining the online daily service of morning prayer, a larger congregation than the 850 it welcomes through its doors at Christmas.
And finally, The Archers has become the latest victim of the coronavirus - with the BBC scrapping one episode a week.
The Telegraph reports that the Friday episode has been cancelled and there will be a shorter omnibus on Sundays.
Inevitably, the paper says, these episodes will contain little or no discussion over a pint in The Bull of the crisis the rest of us are talking about.
But that is entirely to be welcomed, it adds. It will be nice to listen to how life used to be, and will be again.
