Mr Khan said the Conservatives were being “unpatriotic” for “doing our city down”.

“It’s another example of my fear materialising, which is this election, from the Conservative Party, will be one where there’s misinformation, where there’s lies and, in this case, clearly videos that weren’t of this city, it was New York,” he said.

Ms Hall distanced herself from the video, telling BBC News she had not seen the first version, with the New York clip, or the reuploaded version.

Asked about the claims made and messaging in the video, she said: “I’m out listening to Londoners and all they are telling me is that they are concerned about the violence on our streets.”
