Exercise outside the home could be banned if people ignore coronavirus social distancing rules, the health secretary has warned.
Matt Hancock told the BBC’s Andrew Marr that the government would “take action” if further measures are needed to bring the coronavirus under control.
It comes after reports of groups of people gathering in parks during sunny weather this weekend.
The death toll in the UK reached 4,313 on Saturday.
Mr Hancock said: “If you don’t want us to have to take the step to ban exercise of all forms outside of your own home, then you’ve got to follow the rules.”
The health secretary said the vast majority were sticking to the guidelines, adding: “Let’s not have a minority spoil it for everybody.”
He said the timing of restrictions being lifted would depend on how people behave, adding that “the more people stay at home the less the virus will spread”.
Speaking to Sky’s Sophy Ridge earlier, Mr Hancock said sunbathing in public spaces was against the government’s coronavirus social distancing rules.
It comes as Brockwell Park in Lambeth was forced to close on Sunday after more than 3,000 people spent the day there sunbathing or in large groups on Saturday.
There were similar scenes on Primrose Hill in Camden on Saturday, when police moved on more than 100 people.
But local officers tweeted to say thank you after finding far fewer crowds in the area on Sunday.
And Brighton beach was nearly deserted on Sunday, following a warning by Brighton and Hove City Council that too many people were meeting up with friends on the seafront.
Meanwhile, two people have been summonsed to attend court after having a barbecue on Hove beach, Sussex Police said.
The Met Office said some parts of the UK could see temperatures of up to 21C on Sunday, with blue skies and sunshine forecast for much of the day across the country.
Restrictions state that everybody must stay at home where possible, and only leave if they have a “reasonable excuse”, such as exercise or shopping for basic necessities.
Newly elected Labour deputy leader Angela Rayner told Sophy Ridge it was “all right for people who have got big houses and huge back gardens” to tell sunbathers observing social distancing to stop doing so.
“If you’re stuck in inadequate accommodation… and you’re all on top of each other, quite literally, then I think people should do social distancing and should keep their distance, but also be reasonable and proportionate about that,” she said.
Harriet Harman, MP for Camberwell and Peckham, has called for a rota for the use of public parks, writing on Twitter that families in flats with young children need green spaces during the lockdown.
Mr Hancock’s warning came ahead of the Queen’s address to the nation on Sunday, in which she will stress the value of self-discipline and resolve during the coronavirus pandemic.

Mr Hancock said the physical and mental health benefits of exercise were “really important”, and that he did not want to remove exercise as a reason to leave home.
But he added: “If the result of that is that too many people go out and flout the other rules because they say ‘well if I can exercise then it’s fine for me to do other things’ then I’m afraid we will have to take action.”
New Labour leader Sir Keir Starmer said the party would support the government it if decides to toughen lockdown measures.
“We’ve got to get through this and every time people break the guidance from the government they put other people at risk,” he said.
Prime Minister Boris Johnson tweeted his thanks to “everyone who is saving lives by staying at home this weekend”.
“I know it’s tough, but if we all work together and follow the guidance we will beat coronavirus,” he said.
Mr Hancock said that the number of ventilators needed over the coming weeks will be 18,000, and that currently there are between 9,000 and 10,000 within the NHS.
When asked about the number of nurses that had died of coronavirus, Mr Hancock said the latest figure was three deaths.
Also on the BBC’s Andrew Marr show, Prof Neil Ferguson of Imperial College London said he could not predict when the lockdown would be lifted.
He said there was “no point” in releasing the lockdown “at a point where case numbers are still high and will resurge even faster than we have seen before.”
Prof Ferguson added: “We want case numbers to get to a low point where we can start substituting other measures for the most intrusive and economically costly aspects of the current lockdown.
“Almost certainly those additional measures will involve massively ramped-up testing, going back to trying to identify contacts of cases and stopping chains of transmission.
“That can only feasibly be done when we have many fewer cases per day than we have at the moment.”
Mr Hancock told Sky it was “quite unbelievable” that a minority of the public are not following the lockdown social distancing advice.
The health secretary also dismissed speculation that he and Chancellor Rishi Sunak have different opinions about when to lift the strict measures.
“We’re working very closely together,” he said. “What matters is that we get out of this as soon as possible.”
The Queen’s address will be broadcast on TV, radio and social media at 20:00 BST.
The latest figures – showing 4,313 people with the virus had now died in the UK – were up by 708 on Friday’s figure.
This included a further 46 people in Scotland, 13 people in Wales and eight more in Northern Ireland.
There are now 41,903 confirmed cases, the Department of Health said.
