Former Commons leader Lucy Powell has been crowned Labour's new deputy leader in a closely fought race against Education Secretary Bridget Phillipson.
Ms Powell received 87,407 votes to Ms Phillipson's 73,536 - a majority of 13,871 - in a contest that was widely perceived as a referendum on Sir Keir Starmer's popularity with the membership.

Ms Powell was seen as the "anti-Starmer" candidate given she was sacked from cabinet just last month, and centred her campaign on being an independent voice for the backbenches.
Ms Phillipson was seen as Number 10's preferred option, and she had pitched herself as the "unity candidate", warning that voting for her opponent would result in "internal debate and divisions that leads us back to opposition".
However speaking to Sky News's political editor Beth Rigby following the result, Ms Powell insisted she would be a "friend" to the prime minister, adding: "I am confident we can work well together."
She said she was not here to "write an alternative policy platform" but rather "to make sure Labour values and beliefs are right at the heart of the conversation, and that we're giving a really clear sense of who we're for".
Ms Powell's earlier victory speech made clear where she thinks Labour is going wrong, and what she will challenge the government on.
The Manchester Central MP said Labour "won't win by trying to out-Reform Reform, but by building a broad progressive consensus".
She said that starts with "wrestling back the political megaphone" from Reform leader Nigel Farage, "and setting the agenda more strongly".
"Let's be honest, we've let Farage and his ilk run away with it. He wants to blame immigration for all the country's problems. We reject that," she said.
"Our diagnosis is different, that for too long the country and the economy has worked in the interests of the few, not the many."
The reference to "for the many not the few" - the slogan during Jeremy Corbyn's time at the helm, was not lost on his then shadow chancellor John McDonnell.
The veteran left-winger said on X: "The Labour Party members have spoken & the message is clear, they want change. It's good to see a return to references to the Labour Party serving once more the many not the few & that Labour must not try out Reform, Reform. Our members realise a new start is desperately needed."
'Unwanted deputy imposed on PM'
The deputy leadership role is important as it's the key connection between the Labour members and the upper echelons of the Labour Party.
The race was triggered by the sudden departure of Angela Rayner, after she admitted to underpaying stamp duty.
The scandal sparked a reshuffle in which Ms Powell was one of the only casualties. It makes the new partnership potentially very awkward for Sir Keir, especially as his new deputy will be free to speak out against his policies from the back benches rather than being bound by collective responsibility like Ms Phillipson.
However in a possible olive branch, Sky News understands Ms Powell will be asked to attend political cabinet meetings, even though she will not officially be a member of cabinet.
Tory chairman Kevin Hollinrake said "weak Keir Starmer" has had an unwanted deputy leader "imposed on him by the Labour Party", adding: "The failure of the Keir Starmer candidate, Bridget Philipson, is another defeat of the prime minister's authority."
Turnout for the vote was low - just 16.6%, suggesting a lack of enthusiasm among party members and its affiliates.
Sir Keir congratulated Ms Powell after the results were announced, saying she "has always been a proud defender of Labour values, and that is exactly what we need at this moment".
He echoed some of her language around immigration, as he attacked the Tories for this week suggesting they supported a policy to deport people who have settled in the UK legally, something Reform UK has advocated.
"That is what we're up against on the right of politics, a politics of division and grievance that wants to take this great country to a very dark place", Sir Keir said.
PM warns of 'battle for the soul of our nation'
The PM is under pressure as the party plummets in the polls, with many MPs on the left predicting he could be gone by May if the local elections go badly.
Sir Keir acknowledged Labour is having a difficult time after it lost the Caerphilly by-election to Plaid Cymru on Thursday.
He said it was a "bad result" and "a reminder that people need to look out their window and see change and renewal in their community, opportunities for their children, public services rebuilt, the cost of living crisis tackled".
"We must unite. We must keep our focus on what is, in my view, the defining battle for the soul of our nation. I know that Lucy will do just that," he said.
Today's result is the culmination of a six week contest, with the pair having had to secure nominations from 80 MPs in the first round and then win the backing of 5% of local parties or Labour affiliated groups before making it to the final vote.
Initially six candidates entered, but it quickly became a two-horse race as only Ms Powell and Ms Phillipson reached the 80 threshold, following claims from the left of a "stitch up".
Ms Phillipson said she was "disappointed to lose" but Ms Powell "has my full support".
She added: "What we all need to do now is unite this party, beat Reform and secure that second term Labour government."
