Over 300 anarchists are expected to march on Boris Johnson’s central Islington home next Friday night.

It will the second march by the Class War movement in a campaign against the “elitist” foreign secretary. About 100 people attended the first march, on July 15, which saw three arrests.

Ian Bone, founder of Class War, told the Gazette today: “We are back because we didn’t see Boris last time. And we are going to keep coming back until he comes out.”

After it emerged the Met is spending £22,000 a year servicing three unused water cannons bought by Mr Johnson when he was Mayor of London, Mr Bone added: “We will be bringing some super soakers of our own.”

Police were present at the march earlier this month, but a Met spokesman would not comment on plans for next Friday: “We don’t discuss policing plans until much nearer the time.”
