Angela Rayner has spoken out after her removal as Labour Party chair in the wake of the party's disappointing election results.
The Labour Deputy Leader was moved from her role as Labour chair and handed the post of shadow chancellor to the Duchy of Lancaster in a reshuffle announced late on Sunday night.
Sir Keir Starmer's decision to move Ms Rayner on from her role in charge of Labour's election strategy prompted criticism from some and reportedly met with a backlash from his deputy herself.
And late on Sunday, she was installed as the successor to Rachel Reeves, who was promoted to shadow chancellor after Anneliese Dodds was removed.
Ms Rayner called for "solidarity" in a statement on Twitter on Sunday night, and referenced her other new brief as shadow secretary of state for the future of work by vowing to bring "well-paid jobs" to all corners of the country.
The Guardian reports that the move came after a 'prolonged standoff' with Ms Rayner, who was 'locked in talks with the party leader’s team for hours on Sunday."
The paper claims that the party leader had offered her a frontbench role covering the social care brief but she "regarded that as a significant demotion and was determined to maintain influence over internal Labour politics and policy".
Ms Rayner said on Twitter : "I came in to politics as a shop steward standing up for care workers on the minimum wage. In my new roles I will focus on the future of work and the future of our economy, working with our trade union movement to deliver good, well-paid jobs in every region and every community.
"I will take the fight to the Tories on their dodgy contracts and sleaze. And I will set out Labour's policy to replace Tory cronyism and cash for mates with an insourcing revolution so that public services are delivered in the public interest, not for private profit.
"I will work tirelessly to reform our party and deliver a policy agenda that will enable us to reconnect with the voters that we need to win, especially in our traditional heartlands, and show that the Labour Party speaks for the working class. That is our founding mission.
"I also want to thank friends from all across the Labour Party and our movement who have been in touch with me. United we stand, divided we fall. The past we inherit the future we build. Solidarity."
Outgoing shadow chancellor Ms Dodds was given the role of party chair, while the reshuffle also led to Nick Brown being replaced as shadow chief whip by Alan Campbell, while Thangam Debbonaire has been moved to shadow Commons leader.
She replaces Valerie Vaz, who was ousted from the shadow cabinet as part of the shake-up, with Lucy Powell taking the shadow housing secretary post.
Lisa Nandy, whose role as shadow to Foreign Secretary Dominic Raab was rumoured to be under threat, has remained in position.
Sir Keir said election results in Scotland and Wales, along with the host of mayoral wins in England during the Super Thursday elections, gave the party "optimism and inspiration for the future".
But he said Labour would "require bold ideas and a relentless focus on the priorities of the British people" to regain power once again.
As well as losing the crucial Hartlepool parliamentary by-election, Labour lost hundreds of council seats, many in their former strongholds in the Midlands and North.
"The challenge for us now is to build upon these successes and learn from the places we lost," Sir Keir.
"I look forward to working with our refreshed and renewed team to take on that challenge, deliver that change and build the ambitious programme that will deliver the next Labour government."
