Mitchell faces new rant threat

■ Conservative cabinet minister Andrew Mitchell last night faced a renewed challenge to his position after the log of his altercation with a Downing Street policeman was leaked to the press. The chief whip admits confronting officers last Wednesday night after they refused to let him ride his bicycle through the street’s main gates but has denied claims that he called them “plebs” and “morons”. But last night the Daily Telegraph published the leaked police record of the incident, which quotes him as saying: “Best you learn your f****** place... you don’t run this f****** government... you’re f****** plebs”. Prime Minister David Cameron had attempted to draw a line under the issue yesterday morning by giving Mitchell his support.
