Labour MP Sarah Champion has returned to the shadow cabinet, just a month after quitting her position in the middle of the Labour coup and describing Jeremy Corbyn's position as "untenable".
In a highly unusual un-resignation letter first published on the Guido Fawkes blog, Champion asked "to formally retract my resignation and ask to be reinstated to my role as shadow Home Office minister for preventing abuse and domestic violence with immediate effect".
Corbyn has accepted her un-resignation and she will now return to being a junior shadow minister.
One Labour source told BuzzFeed News that Champion had actually submitted her un-resignation letter on 20 July but it has only just been made public.
The Rotherham MP quit on 28 June, along with dozens of other Labour shadow ministers, in a failed attempt to force Corbyn to quit his job.
I have just stepped down from my shadow minister job, but not my responsibilities to my constituents, party or victims of abuse
At the time of her resignation Champion said Corbyn's leadership "is now untenable" and defended her decision to quit in a series of tweets saying the party could not be "an effective opposition" in its current state.
Because his leadership is now untenable & we had a motion of no confidence that he chose to ignore https://t.co/W6lhvSbGuY
I haven't. I'm being realistic that PLP won't unite behind him & without that we can't be an effective opposition https://t.co/NAApY0Nwef
She also insisted there were no better options and Corbyn's leadership was stopping the party from fighting the Conservatives.
If I could see a better option I assure you I would have taken it. https://t.co/lPwAC2UkQK
Not siding with anyone. I believe Jeremys leadership is now untenable & we need a Labour Party that can fight Tories https://t.co/JbzUrSdHsl
It is unclear whether Champion now feels Corbyn's leadership is tenable and the party is now able to fight the Tories.
