Names have begun to emerge in what will likely be a tense and toxic contest to replace Jeremy Corbyn as the Labour Party's candidate for Islington North at the next general election.
The party formally launched the process to select its candidate for the north London seat after months of uncertainty.
Sir Keir effectively barred his predecessor from ever standing as a Labour candidate when he proposed a motion by the party's ruling body, the National Executive Committee (NEC), which said Mr Corbyn "will not be endorsed by the NEC as a candidate on behalf of the Labour Party at the next general election".
It cited the dismal defeat Mr Corbyn led Labour to as leader in the 2019 general election in arguing his candidacy should be blocked and said the party's chances of securing a majority in the Commons would be "significantly diminished" if he was endorsed.
Mr Corbyn has been without the party whip - meaning he cannot sit as a Labour MP in the Commons - since 2020 following his response to a report into antisemitism within the party by the Equalities and Human Rights Commission, which Sir Keir and his allies felt downplayed the significance of the problem while he was leader.
Since the passing of the NEC motion, speculation has been rife as to what Mr Corbyn's future could hold.
