Posting because this changed materially over the weekend.
Wes Streeting confirmed on Saturday at the Progress conference that he will stand in any Labour leadership contest, AND he explicitly called for the UK to rejoin the EU. He described leaving as "a catastrophic mistake" and said "Britain's future lies with Europe and one day back in the European Union." Andy Burnham, the other leading challenger, has separately told ITV "in the long-term, there is a case for that" rejoining, though he hasn't put it at the centre of his Makerfield bid.
Both have said any move would need a fresh electoral mandate. Streeting frames it as Labour's next manifesto.
Reform UK's response was instant. Farage on the Telegraph: "Open borders Burnham must be stopped." Reform won every council ward in Makerfield at the May 7 locals (around 50% of the vote, Labour at 25%), so the by-election Burnham is fighting just became the first concrete test of where rejoin sentiment actually sits.
The bit I had not seen joined up anywhere was the structural read: if both viable Labour leadership contenders are openly on rejoin, the 2029 general election is now substantively a Brexit-redo. Reform UK ran in 2024 on Brexit-was-correct. That assumption is now contested by the people closest to the current government.
