Huhne threatens AV legal action

Energy Secretary Chris Huhne has threatened legal action over what he has described as 'untruths' made by coalition colleagues about the campaign to change the voting system at Westminster.

Mr Huhne accused senior Conservatives of making false claims about the costs of introducing the Alternative Vote.

Foreign Secretary William Hague insisted the coalition was working well, despite feelings 'running high'.

The BBC's Laura Kuenssberg reports.
