How would a Labour leadership contest work?

"MPs unhappy with Sir Keir remaining in post could try to force a leadership election. This would require 20% of the party's MPs to back a replacement candidate. There are 403 Labour MPs, so the support of 81 would be needed. Once a Labour leadership election is triggered, other candidates could join the contest if they also have 81 backers. Sir Keir would not be required to gather support as he would be automatically on the ballot paper if he chose to contest the lea"

Sir Keir Starmer faces pressure from dozens of Labour MPs to resign immediately or set a timetable for departure. Starmer says he intends to continue governing because no formal leadership challenge has been launched. Labour’s recent election performance has been poor, including major losses in local elections across England, losing power in Wales, and its worst-ever result in the Scottish Parliament. More than 80 Labour MPs have called for Starmer to leave or announce a resignation date. Several ministers have resigned, including Jess Phillips, Miatta Fahnbulleh, and Alex Davies-Jones. MPs seeking change could trigger a leadership election by securing support from 20% of Labour MPs, which is 81 of 403.
