Ed Miliband has confirmed he will attend the televised debates. In his speech to the Scottish Labour party, Miliband poured scorn on David Cameron's attempts to get out of the debates:

“This is what David Cameron used to say about TV election debates:

That they were essential to our democracy.

That every country apart from Mongolia had them.

That he wasn’t going to have any feeble excuses to get out of debates.

And now he is doing everything he can to stop them.

And it is on the issue of leadership debates that David Cameron’s duplicity has caught up with him.

He says this election is all about leadership, all about the choice between him and me, and when it comes to a debate between him and me, he’s running scared.

He’s running away.

I say to David Cameron:

You can refuse to face the public, but you can’t deny your record.

You can try to chicken out of the debates, but don’t ever again claim that you provide strong leadership,

You can try to escape the people’s debates, but you can’t escape the people’s verdict.

Today the Labour Party has written to the broadcasters.

Saying with or without David Cameron, I will be at the debates.

And every day up to these debates he will be asked: what are you hiding from?

When all people will see is an empty chair, his claims of leadership will be exposed as empty.”
