Chris Huhne says speeding allegations are incorrect

Lib Dem minister Chris Huhne has said allegations he asked someone else to take his penalty points for a 2003 speeding offence are "simply incorrect".

Downing Street said the prime minister had "full confidence" in Mr Huhne after it emerged police were investigating whether an offence took place.

The findings will decide whether a formal inquiry is launched. The energy secretary said he welcomed the police investigation.

He said the allegations had been "made before and been shown to be untrue".
