‘Don’t go into the dark’: Cameron urges Boris to back EU 'remain’ campaign

David Cameron has urged Boris Johnson to back the campaign for Britain to remain in the EU ahead of the London mayor announcing who he supports. The Prime Minister was using an appearance on the BBC’s Andrew Marr programme to set out his arguments for why people should vote for Britain to stay in Europe. He said: I will say to Boris what I say to everybody else which is that we will be safer, stronger and better off inside the EU.“

I think the prospect of linking arms with Nigel Farage and George Galloway in a leap into the dark is the wrong step for our country and if Boris and others really care about getting things done then the EU is one of the ways that we get things done.

The Mayor of London and MP, who also sits in Cabinet meetings, is today expected finally to declare which side he will be supporting over Europe, ending months of prevarication. He is the last major politician to announce his voting intentions after David Cameron fired the starting gun on the in-out referendum, to be held on 23 June. Mr Cameron will use a speech in Parliament on Monday to explain the detail of the "special status” he says he won for Britain after marathon negotiations in Brussels last week. Mr Johnson’s sister, journalist Rachel Johnson, told Sky News that her brother was genuinely torn and was not milking his apparent indecision for political advantage.

Who know’s what Boris is about to do. I’d given up trying to figure that out years ago.
