England’s most senior police officer has urged people to “be calm, be sensible” when pubs reopen on Saturday.
The commissioner of the Met Police, Dame Cressida Dick, said police had been preparing “for some time” and had “extra resources in place”.
Greater Manchester Police said it had planned a “significant” operation, while night marshals will be deployed to support officers in Leeds.
Pubs in England have been closed since March to slow the spread of Covid-19.
But Prime Minister Boris Johnson announced last Tuesday that they – as well as bars and restaurants – would be able to reopen on 4 July, with certain restrictions.
Dame Cressida said that she was “not predicting” violence but that there would be “a lot” of officers on the streets, with “more ready… should people get violent”.
“My message is, if you’re coming out on Saturday, be calm, be sensible,” she told BBC Radio 4’s Today programme on Tuesday.
“Look after yourself, look after your family. We are still in a global pandemic which is affecting this country very obviously.”
Her warning comes after officers were attacked as they tried to break up unlawful gatherings in London last week, with at least 22 officers injured during unrest in Brixton.
