Jeremy Corbyn will announce his intention to oppose Labor in the general election in his Islington North constituency.
ITV has reported that the former Labor leader will confirm his candidacy today, with a hammer blow Keir Starmer.
Allies of Corbyn believe he can win the seat and remain in parliament, despite Labor currently having a majority of 26,188.
Corbyn, who has represented the north London seat since 1983, is hoping for a large personal vote of loyalty from his current voters, and its central location in London will allow far-left activists to travel there easily to help him campaign to feed.
Last night Labor announced its shortlist of candidates for the seat, with two local London councilors selected to contest an election bid.
Sem Moema, member of the London Assembly and councilor for Hackney, made the shortlist, alongside Islington councilor Praful Nargund.
Journalist and left-wing activist Paul Mason missed.
Last night, Corbyn's former ally and shadow chancellor, John McDonnell, voiced support for his independent campaign and warned Labor that Corbyn will receive a lot of “personal support”.
However, he expressed the hope that Sir Keir Starmer will still see a “Damascene conversion” and allow the former leader to stand as a Labor candidate.
In March last year, Labour's NEC passed a motion to block Corbyn as the Labor candidate by 22 votes to 12.
The motion said Labour's chances at the election would be “significantly reduced if Mr Corbyn were supported”.
It argued that “the interests of the Labor Party, and its political interests at the next general election, will not be well served by Mr Corbyn standing as a candidate for the Labor Party”.
In response, Corbyn said blocking his candidacy was a “shameful attack on party democracy, party membership and natural justice”.
He accused Mr Keir Starmer of “launching an attack on the rights of his own Labor members”.
“I will not be intimidated into silence. I have spent my life fighting for a fairer society on behalf of the people of Islington North, and I have no intention of stopping now.”
He has pledged to 'continue to serve' his constituents, in a subtle hint about his future plans.
The Sunday Times has also reported that an activist at Corbyn's office inquired at a printing company about the costs of having election leaflets made.
However, a spokesperson for the former Labor leader denied approving the emails.
