David Miliband slams brother Ed's election campaign failure
David Miliband has criticised his brother Ed's general election campaign but ruled himself out of running for Labour leader.
David, who runs a charity in New York after quitting British politics when Ed beat him to the Labour leadership in 2010, said voters "didn't want what was being offered".
He added: "I'm clearly not a candidate in this leadership election, the commitment I have to the job I've got doesn't change."
David said he would not endorse any candidate but added: "I hope that a range of leadership candidates will come forward - I am not here to endorse any candidate.
"What I think it vital is there is absolutely no delusion about what happened, why it happened, and the scale of the challenge that exists not just in England and Wales but in Scotland as well.
"Both in 2010 and 2015, Gordon (Brown) and then Ed allowed themselves to be portrayed as moving backwards from the principles of aspiration and inclusion that are at the absolute heart of any successful progressive political project.
"The answer is not to go back to 1997, it's to build on the achievements and remedy the weaknesses, but never to end up in a position where the electorate think you are going backwards rather than addressing the issues of the future."
David said last week's election result was "devastating" for the Labour Party.
But he said: "There's absolutely no point in blaming the electorate. Any suggestion that they didn't 'get it' is wrong. They didn't want what was being offered."
Asked if he would return to Britain to put himself forward as a contender to replace his brother as leader, he said: "I'm clearly not a candidate in this leadership election.
"I'm here in New York. I'm running a global charity that's delivering aid to millions of people around the world.
"The commitment I have to the job I've got doesn't change as a result of the election."
