A Lambeth Council spokesperson said: “Unfortunately Brockwell Park will be closed on Sunday. This is to ensure people observe the critically important social distancing measures needed right now to fight coronavirus.
“Despite clear advice, more than 3,000 people visited Brockwell Park on Saturday, with some visitors sunbathing and congregating in large groups. This is unacceptable at this time.
“Unfortunately, the actions of this minority means that, following police advice, Brockwell Park will be closed on Sunday.
“We thank people for their understanding at this incredibly difficult time. The single most important action we can all take, in fighting coronavirus, is to stay at home in order to protect the NHS and save lives.”
