UK televised leader debates: 'It's pointless without David Cameron"

Lord Grade, former chairman of the BBC, chief exec of ITV and Roger Mosey former editorial director of BBC TV News discuss David Cameron's decision not participate in a televised leaders' debate unless the Green Party is included.

Michael Grade tells Radio 4 Today's programme "It's all rather pointless without David Cameron..."

"It's very complex, everyone is looking for an advantage...but what the public really want to see is Miliband and Cameron".

However Roger Mosey, former editorial director of the BBC, said the debate should go ahead even if Cameron declined to attend.

He told Today's James Naughtie: "If one party declines and everyone else turns up then it would be wrong not to have a debate."
