AV campaign rows causing coalition conflict, says Huhne

Senior Liberal Democrat minister Chris Huhne has threatened legal action over "untruths" told by Conservatives opposed to the Alternative Vote system.

Mr Huhne said Tory ministers backing the No campaign undermined their credibility by making false claims about the costs of introducing AV.

He warned the row could damage the coalition government.

Foreign Secretary William Hague denied Tories had told "untruths", and said the coalition could still work well.
