Sir Keir Starmer will announce his bid to replace Jeremy Corbyn as Labour leader in the Sunday Mirror tomorrow.

The Shadow Brexit Secretary revealed his leadership bid speaking exclusively to the Sunday Mirror and admits Labour face an “uphill struggle” against Boris Johnson ’s Commons majority.

But he says the party must hold the Tory government to account for the promises they made before the election.

The Shadow Brexit Secretary will launch his campaign during a visit to Brexit-backing Stevenage.

Tonight he released a video featuring Doreen Lawrence, the mother of murdered Steven Lawrence - telling the story of his career including his work as a legal advisor to the National Union of Mineworkers (NUM), environmental activists and people fighting the poll tax.

“I’m proud to be announcing by candidacy for the Labour leadership in the Sunday Mirror today,” he said.

“Over the coming weeks, I’m looking forward to getting back on the campaign trail and talking to people from across the country about how Labour can rebuild and win.

“Britain desperately needs a Labour Government. We need a Labour Government that will offer people hope of a better future.

“However, that is only going to happen if Labour listens to people about what needs to change and how we can restore trust in our party as a force for good.”

Sir Keir became the fifth Labour MP to formally throw their hat in the ring for the top job.

Friday night saw both Jess Phillips and Lisa Nandy launch their campaigns.

Shadow Foreign Secretary Emily Thornberry and Shadow Economics Minister Clive Lewis had already officially declared.

Shadow Business Secretary Rebecca Long Bailey, a Jeremy Corbyn ally favoured on the left of the party, is still “seriously considering” whether to run for the leadership - as is party chairman Ian Lavery, who is also close to Mr Corbyn.

But London MP David Lammy ruled himself out of the race on Saturday.

He said: “I’m committed to playing my full part in opposition, but we need the candidate best placed to unite our party’s factions so we can win the country’s trust.”

Ms Phillips visited the Bury North constituency that fell from Labour to the Tories to meet former supporters who did not back the party in the last election.

The long-term Corbyn critic warned in a separate statement that Labour is in “big trouble” if it cannot win back the trust of its working-class base.

“We have got to be brave and bold and bring people with us, not try and look all ways. Trying to please everyone usually means we have pleased no-one,” she said.

“Now is not the time to be meek. Boris Johnson needs to be challenged, with passion, heart and precision.

“We need to recognise that politics has changed in a fundamental way by electing a different kind of leader. More of the same will lead to more of the same result.”
