Ed Miliband has insisted his brother David is providing him with "huge support", even though the former foreign secretary plans to be out of the country when the Labour leader delivers his speech to the party conference in Liverpool.
Speaking on the BBC's Andrew Marr programme on Sunday morning, Ed Miliband said he and David had "moved on" from the battle over the leadership that was said to have left their relationship strained.
"He is providing huge support to me as a brother. It's support I'm incredibly grateful for," he said.
"He's doing his own thing, he is getting on with helping us. There's something called Movement for Change which he has founded to help organise people in Labour parties up and down the country so they can go out and make a difference in their own area."
It has been a year since Ed narrowly beat his brother to the top job in the party. He told Marr: "we've moved on and I think everyone else should too".
But David is expected to miss his brother's keynote speech to the conference on Tuesday, as he has plans to jet off the United States in order to attend a meeting on China.
He is however due to make a fleeting appearance in Liverpool to speak at a 'Movement for Change' fringe meeting on Sunday evening.
Writing on his blog, David praised his brother's leadership of the party.
"The mood music from Ed and the leadership about the aims and objectives of the conference has been just right," he said.
"Ed has led the party with conviction and purpose over the last year, and his sense of direction should transmit itself to the troops."
But in an earlier post on his website, he said his presence at the conference would be a "distraction".
"Ed is the leader and he needs an open field in which to lead the party as he sees fit. I don't want to be a distraction. So I am not going to be a talking head providing commentary on TV, or a media focus for soap opera during the week. It's Ed's show and I want it to be a success," he said.
Asked if he would welcome his brother into the shadow cabinet, Ed said: "of course". But added that it was up to David whether he wanted to accept a position.
