Other centrist candidates are likely to include Keir Starmer, who speaks for Labor on Brexit, and Emily Thornberry, the keynote speaker of the party's foreign affairs. Ms. Thornberry, who was once an ally of Mr. Corbyn, took a stronger stance against Brexit than he did, just like Mr. Starmer. Both were largely left out of the campaign. Other candidates could be Angela Rayner and Jess Phillips.
Labor Party members will ultimately choose the next leader, and many are loyal to Mr. Corbyn and his economic agenda, although a majority rejects Brexit. And in a poll among them earlier this year about potential successors, they rated Mr. Starmer as the best candidate with twice as much support as Ms. Long-Bailey.
It is not surprising, then, that Mr. Corbyn's allies are already accusing Thursday of the Brexit defeat on Thursday, arguing that Labor in the north and in the middle of the country lost because of a second Brexit referendum under the Offered pressure from survivors like Mr. Starmer.
Ian Lavery, the party leader who wants to continue Brexit and is an ally of Mr. Corbyn, argued that the cause of the defeat was "not Brexit and Brexit and ignoring democracy".
However, there are deeper structural reasons for the loss of Labor support in the parts of the north and center of the country that ceded to the Tories.
"Brexit accelerated but did not trigger a massive change in voting behavior," said Peter Kellner, a political analyst and former president of YouGov, an electoral organization.
By the mid-1980s, around 80 percent of Labor's support came from workers and their families. With the decline of large-scale industries, coal mines, shipyards and steelworks, workers 'voters were more numerous in 2010 than workers' voters.
