Context:

Brexit becomes a salient fault line as Labour’s internal leadership jockeying and a Makerfield by-election bring the issue back onto the political radar. Wes Streeting, in his first public appearance since resigning, called Brexit a catastrophe and signaled a challenge to Keir Starmer, arguing Labour must pursue a new relationship with the EU if given a fresh mandate. Andy Burnham’s stance is tested as he canvasses Makerfield; while cautious about endorsing rejoining the EU in this by-election, he has kept open the long-term possibility. The debate draws in Reform UK and other parties, highlighting enduring divisions over Brexit and the path to growth, with implications for Labour’s leadership and electoral strategy going forward.

Dive Deeper:

• Wes Streeting, at the Progress Conference, declared Brexit a catastrophic mistake and announced a formal challenge to replace Sir Keir Starmer, framing Brexit as a pivotal issue for Labour policy and leadership.

• Conservative Chair Kevin Hollinrake promptly criticized Streeting, arguing Labour’s Brexit relitigation is a distraction from concerns like the cost of living and public services, signaling heightened partisan tension around the issue.

• Streeting argued Labour must move beyond ‘overcautiousness,’ outlining three major choices and asserting a future path for Britain that involves a new special relationship with the EU, contingent on a new mandate such as a general election.

• Makerfield by-election is anticipated around 18 June, with Andy Burnham actively campaigning; he indicated a long-term case for rejoining the EU but said he isn’t advocating that in the by-election context, maintaining respect for the referendum outcome.

• Reform UK leveraged Makerfield’s Brexit sentiment—citing 65% of local voters backing Brexit in 2016—and claimed the by-election results could shift political momentum, noting Reform’s roughly 50% vote share in the ward while Labour polled about half that.

• Local dynamics show Labour’s challenge from Burnham, Reform UK’s activism, and cross-party pressure from Lib Dems and Greens, with party leaders increasingly framing Brexit as central to national growth and sovereignty.

• The piece underscores Brexit as a decisive fault line that shapes leadership contests, electoral strategy, and the future of Labour’s stance toward EU integration, with broader implications for UK politics.
