Plenty of people were out enjoying the sunshine on Saturday despite government pleas to stay home.
Prime Minister Boris Johnson and Health Secretary Matt Hancock were among those who urged the public not to go outdoors this weekend after warmer weather was forecast, with 18C (64.4F) possible on Sunday.
But pictures from parks and beaches across the UK seemed to suggest some just could not resist the temptation to leave their homes on Saturday, with blue skies above much of the country.
And while most at least appeared to be keeping their distance from others, not everybody appeared to be respecting official guidance regarding when people should be going outside.
The government says people should not be leaving the house unless their work requires them to do so, to shop for essential supplies such as food, to exercise once a day, or for health reasons.
Mr Hancock said on Friday: "This is not advice, these are instructions."
But gatherings were seen in Regents Park, London Fields, Battersea Park and other green spaces in London, with thousands said to have flouted advice at one park in the south of the capital.

Brockwell Park has said it will be closed on Sunday because so many visitors had ignored social distancing.
On Twitter, the park said: "Despite clear advice, over 3,000 people spent today in Brockwell Park, many of them sunbathing or in large groups. This is unacceptable."
The local council later added: "We are sorry we've had to take this decision. This wouldn't need to happen if people followed the clear instructions from the government.
"We are doing this for the wider safety of the public, a minority of people have not followed the guidance and so regrettably we have had to act."
