Ed Miliband has said the "door was open" for his brother David to return to front line politics but he has taken the decision to take on a new role based in New York. The Labour leader said his brother will be "serving the world" with his new charity position:
The former Foreign Secretary David Miliband has told ITV News: "I am leaving politics."
He told political editor Tom Bradby it is "not fair for me to spend my time looking backwards and inwards" about losing the Labour leadership election to his brother Ed.
He denied any falling out with his brother: "We fought a leadership election but we don't fight each other, Ed and I. That's not the Miliband way."
But he admitted: "Is it tough? Of course it's tough."
He said he "kept him [Ed] informed" about his new role.
Labour MP David Miliband has stepped down as MP to become the president and CEO of the International Rescue Committee in New York. He has tweeted his letter of resignation to Alan Donnelly, chair of the South Shields Constituency Labour Party:
Former Prime Minister Tony Blair says David Miliband will be a huge loss to UK politics
– Tony Blair
"I congratulate David on his appointment to a major international position. It shows the huge regard in which David is held worldwide. I'm sure he will do a great job. He is obviously a massive loss to UK politics. He was the head of my policy unit and then a truly distinguished Minister in the Government and remains one of the most capable progressive thinkers and leaders globally. I hope and believe this is time out not time over.
