After Ed Miliband's election victory, who are the likely winners from within the Labour Party?

Ed Miliband's election promises a shift in Labour's centre of gravity. Who Knows Who looks at the candidates for promotion.

Ed Miliband didn't get to become leader of the Labour party without the support of, well, the man he defeated, his brother, David.

The leadership campaign is littered with professions of filial love from the two Milibands. Before Ed had even declared, David Miliband stated: "Brotherly love will survive because brotherly love is more important than politics."

Ed reciprocated that view several times, most conspicuously on Saturday afternoon when, having been voted party leader, he told the Labour conference: "David, I love you so much as a brother."

That Ed comes from a political family is well known. His father was the Marxist academic Ralph Miliband. His mother, Marion Kuzak (who, reports say, abstained in the leadership vote), is politically active and is a member of Jews for Justice for Palestinians.

Saturday's vote focused attention on the younger Miliband brother's relationship with his partner, Justine Thornton, an environmental lawyer described by colleagues as well-respected - though not yet pre-eminent in her field.

The couple, who are unmarried, have been together for five years (roughly the length of time Ed has been an MP) and are expecting their second child in November.

They suffered a conflict of professional interests last year when it transpired Justine was involved in a professional capacity in the E.ON group’s bid to build nuclear power stations. At the time Ed was secretary of state for energy and climate change.

Not just a family affair
Outside his family, Ed Miliband's political inner circle is a combination of new generation Labour and old generation Brownite. The political fault-line that defined the Blair-Brown years is still visible.

Shadow transport secretary and former transport minister Sadiq Khan, who helped to mastermind the campaign, is in line for promotion within Labour's hierarchy. It was Khan whom Ed Miliband chose to accompany him into the back room at the Labour conference to learn the outcome of the leadership vote.

Oxford academic Stewart Wood, a former foreign policy adviser to Gordon Brown, also had a directing role in Ed Miliband’s leadership campaign. Characterised by right-wing commentator Matthew d'Ancona as Miliband's "very own Peter Mandelson", he is said to have briefed extensively against his Ed's rivals during the contest. He could be rewarded with the job of the new Labour leader’s communications chief.

(It was Stewart Wood, incidentally, who was at the centre of claims in the Andrew Rawnsley book, The End of the Party, that Gordon Brown had punched an aide.)

Polly Billington, a former BBC Radio reporter, oversaw the media strategy for the victorious campaign. Ed Miliband's adviser since 2007, she is keen to become a member of parliament. She lost out to a local candidate in her bid to become Labour's North Tyneside parliamentary candidate in the 2010 general election.

One female who did make it into parliament in 2010 was economist Rachel Reeves, MP for Leeds West. She has worked at the Bank of England, the British embassy and HBoS, and has written for the Fabian Review and the Institute for Public Policy Research, and is tipped to shadow the chief secretary to the Treasury.

Other movers in the younger Miliband's campaign included Rachel Kinnock, daughter of former Labour leader Lord Kinnock and a Downing Street staffer under Gordon Brown (significantly, it was she who led the new leader on his tour of conference hall), and Lucy Powell, who narrowly failed in her bid to win back the Manchester Withingston constituency from the Liberal Democrats in the general election. Previously head of the pro-EU Britain in Europe campaign group, Powell is tipped to become Miliband's chief of staff.

The coming man
Ed Miliband used three MPs as his parliamentary agents during the contest: Chuka Umunna, John Denham and Hilary Benn. The fact remains, though, that within the parliamentary Labour party David Miliband's campaign was the most successful.

Denham and Benn were both Cabinet members in the last Labour administration, but Umunna is the coming man among the three. A leading member of the centre-left Compass group, he became Labour MP for Streatham in 2010. Umunna is a lawyer by training, and well regarded by leading figures within the party such as Tessa Jowell and Harriet Harman, He has been touted as a possible shadow justice minister.

Arguably more significant in Ed Miliband's victory in Manchester was the role of the unions. Who Knows Who noted last month that he had secured the support of more trade unions than any other candidate. Of the 12 unions affiliated to the Labour party, the four big unions – Unite, Unison, the GMB and Ucatt – voted for Ed.

Jack Dromey, MP for Birmingham Edlington and husband of Labour deputy leader Harriet Harman, organised Ed Miliband's union campaign. He was aided by Charlie Whelan, formerly aide Gordon Brown and currently political officer for Unite the union.

Whelan claims to have had a significant influence on Saturday's result by persuading six union-backed MPs to switch their second preferences from David to Ed. Whether either Dromey or Whelan has a role in the new Labour leader's inner circle remains to be seen.
