Boris Johnson has said he backs Metropolitan Police Commissioner Dame Cressida Dick, who has faced calls to resign for her handling of the Sarah Everard case, and urged the public to “trust the police”.

But the prime minister acknowledged “there is a problem” with how cases of rape and violence against women are handled.

“I do believe in the police. I do think that we can trust the police. And I think the police do a wonderful, wonderful job,” he said.

“But there is a problem. And there is a problem in the way we handle rape, domestic violence, sexual violence and the way we handle the complaints of women and girls. And it’s overwhelmingly women and girls.

“And, although the incidence of some of these serious crimes is not actually going up in the way that you might think – we are having success in getting many crime types down – the problem is we have too few prosecutions for rape and too few successful prosecutions, too few convictions.

It comes as a YouGov poll found 38% of adults in the UK think Dame Cressida should resign.

Of those, 44% of men surveyed thought she should resign compared to 32% of women.

Asked if he has confidence in the Metropolitan Police given the vetting failures, Mr Johnson said: “Yes I do. And I think that needs to be looked into.

“And I think that Priti Patel is absolutely right, we’ve got to get to the bottom of what on earth happened with Wayne Couzens, we need to make sure that nothing like that happens again.

“But what we’re doing is now not just putting more, a lot more money into safer streets, into CCTV… but recruiting more female police officers. And I think that can make the most fundamental change of all.”

Mr Johnson said hundreds of thousands of officers will be “heartsick” by the “appalling murder of Sarah Everard”.

“I think there will be hundreds of thousands of police officers, let alone myself, up and down the country who will be absolutely heartsick by what has happened, the appalling murder of Sarah Everard by a police officer,” he added.

“And what I would really urge the public, I want to make it clear, I do believe in the police.”
