Plaid Cymru leader Leanne Wood welcomes debates pledge

Broadcasters have said plans for three TV general election debates in April will go ahead, despite David Cameron saying he will take part in only one.

It means Mr Cameron - who has rejected a head-to-head debate with Ed Miliband - could be "empty chaired".

Downing Street said it would not back down on its "final offer" of one seven-way debate in March.

Plaid Cymru leader Leanne Wood - one of the seven invited to take part - welcomed the broadcasters' refusal to back down on the issue.
