Anna Turley, the shadow minister for civil society, has resigned from her post becuase she does not believe her party can win an election under Jeremy Corbyn's leadership.
The Labour & Cooperative MP for Redcar, who entered parliament at the general election in 2015, said on Twitter this morning that it was "with great sadness" that she had sent a letter of resignation as shadow charities minister to Jeremy Corbyn, the leader of the Labour Party.
Turley's resignation is one of a raft of departures from top Labour positions over the past 24 hours designed to unseat Corbyn.

She told the Labour leader, who supported Turley's bid to become an MP when she lived in his Islington constituency, that she held him in very high regard and said he was "one of the kindest and most committed public servants in politics".
But she said he had not been providing the "strong, forward-looking and competent leadership we need to provide an alternative government to these increasingly right-wing Conservatives that are doing such damage to this country and to my constituency".
She said the situation had been brought home to her over the past couple of weeks by the "lacklustre referendum campaign".
She wrote: "But it had been increasingly clear to me for some time that the leadership is not in touch with the hopes, the fears and the aspirations of my local constituents.
"I have had a number of party members, and many, many Labour-voting members of the public, tell me this weekend that they do not have confidence in your leadership and asking me to sign the motion of no confidence that was proposed for Monday.
"I’m afraid I share their view and do not believe the Labour Party under your leadership is, or ever will be, in good enough shape to go to the public in an election and ask to serve them in government."
Turley said in an additional statement that it had been a very difficult decision to resign from her role but that she intended to continue representing the voluntary sector from the backbenches.
"The sector is full of the brightest and best and the most dedicated servants of the people," she said.
"I have learnt an enormous amount and intend to carry on the big-picture thinking that so many of you were feeding into from the backbenches. I intend to continue to try to be a voice for the sector in any way I can.
"This is a tough time for the sector but you have the resilience, the passion, the ideas and the people to flourish."
