John McDonnell The leftwinger, who stood for the leadership in the past, is a possible candidate for shadow chancellor.
Regardless of whether he gets that key job, he has had a tremendous summer as campaign agent for Corbyn.
Angela Eagle As a prominent woman respected by the unions, but also the Labour establishment, she is hotly tipped for a senior role.
Jon Trickett The former senior adviser to Ed Miliband is one of the only backers of Corbyn who has experience in Downing Street, as a former parliamentary aide to Gordon Brown.
Richard Murphy The accountant is a high-profile opponent of tax avoidance and one of the architects of Corbyn’s economic policy. The plans have won support from prominent economists and helped give the new leader financial credibility
Len McCluskey The general secretary of Unite has shown his ability to back the winner once again and ensured strong support for opposition to the trade union bill and austerity
Tony Blair The former prime minister made at least three interventions warning against Corbyn, but these just seemed to galvanise support and signal the end of New Labour influence
Gordon Brown It was thought that Brown’s plea for Labour not to become a party of protest could have more of an affect on anti-Blair Corbyn supporters, but his speech appeared to fall on deaf ears
Peter Mandelson Not only did the peer and New Labour architect warn against Corbyn, he urged centrist MPs to fight back. However, talk of organised resistance has effectively dissipated in the face of the new leader’s huge mandate.
Andy Burnham He went from clear frontrunner to second place by a huge margin after a campaign widely regarded as too inconsistent. He may be allowed to join Corbyn’s shadow cabinet, but this will be poor consolation for a man with hopes of being prime minister who has now failed twice to win the leadership.
Ed Miliband The former leader tried to draw a line under New Labour in 2010, but has now been outflanked on the left and made to look tepid by Corbyn. Meanwhile, Labour centrists blame him for introducing the voting system that elected the new leader.
Chuka Umunna The shadow cabinet minister was widely tipped as a potential prime minister, but he withdrew from the race suddenly at the beginning. He then said Corbyn was unelectable and has now resigned after a ‘long chat’ with Corbyn.
