ARCH-TORY Boris Johnson attempted to mock the new Labour leadership yesterday as well as the “crusty” protesters who threw balls at him as he arrived in Manchester.

The London mayor, who Prime Minister David Cameron confirmed will be given a Cabinet post, said: “We need to do more to encourage sport in schools, because they managed to miss me with every projectile.”

And he used his conference address to turn on Labour leader Jeremy Corbyn and shadow chancellor John McDonnell.

He said: “I know there is a generation of young people who can’t remember communism and who think it might be a good idea to ferment (sic) anti-capitalism as if it were some fruity alcopop.

“And so I say to all those £3 Corbynistas — we tried that. We have tried brewing it in Britain in the 1970s … And the result has been the kind of toxic moonshine that sends you blind — give that hooch a miss.”

Mr Johnson was reportedly pelted with balls by disabled activists on his way into conference on Monday.
