CHRIS Huhne has quit David Cameron's Cabinet after being charged with perverting the course of justice over allegations he asked his ex-wife to take a speeding penalty for him.

In a letter of resignation to the Prime Minister, Mr Huhne said he was standing down as energy and climate change secretary to mount "a robust defence" against the charge.

Remaining in the Cabinet would be "distracting" both to his legal fight and to his Government work, he said.

Deputy Prime Minister Nick Clegg said he hoped his Liberal Democrat colleague would "rapidly" clear his name to "return to play a key role in government as soon as possible".

In a letter to Mr Huhne, Mr Cameron said he had made "the right decision under the circumstances" and wished him well for the future. But the Prime Minister made no mention of a possible return to Government after the court case is concluded.

Mr Huhne's departure will force what is expected to be a limited Government reshuffle.
