David Cameron attacks SNP on The Andrew Marr Show

David Cameron looked well hacked off on The Andrew Marr Show just now. The prime minister complained that Mr Marr was repeatedly interrupting him and doing it in a way Mr Cameron said he hadn’t in his previous interviews with Vince Cable and Nicola Sturgeon. “We’ve both been enjoying this interview.”

“I will be taking to the streets,” the PM said, in what sounded like a change of tack and a sign that the party needs to pull some other levers to get where it thought it would be already by now in the campaign. There’s no sign yet that Ed Miliband’s campaign is ready to take that risk so if he does the street routine Mr Cameron will have it to himself.

The main thrust of Mr Cameron’s interview was an attack on the SNP: “these people,” he said contemptuously, “who don’t care what happens to the rest of the UK” will be dictating life in England if they are propping up a Labour minority government. Andrew Marr said the PM was beginning to sound like an English Nationalist, which went down pretty badly.

The news that YouGov’s Peter Kellner has switched his forecast will strike particular fear in Tory high command. He’s a seasoned and very reliable follower of the British political scene who until now has consistently said he expects Mr Cameron to stay in No. 10. Today in The Sunday Times he says he now thinks Ed Miliband could take charge. It will add to nerves at the top of the Conservative machine and make them wonder what other stuff they need to dig out apart from the tea crate.
