Makerfield By-Election: A Pivotal Test for Labour’s Leadership
6/18/2026, 9:03:31 AM
Core Contest: Makerfield By-Election Overview
On Thursday, voters in the Makerfield constituency of northwest England will elect a new Member of Parliament after Labour MP Josh Simons resigned to create a by-election. Approximately 75,000 eligible voters will decide between Andy Burnham, the Labour mayor of Greater Manchester, and Reform UK candidate Rob Kenyon, a local plumber. Burnham’s victory would give him a seat in the House of Commons and position him to challenge Prime Minister Keir Starmer for Labour’s leadership under party rules that require support from at least 81 MPs (one-fifth of the parliamentary party).
Background: Labour’s Recent Turbulence
Since the Labour Party’s landslide win in the 2024 general election, Prime Minister Keir Starmer’s government has faced criticism over stagnant economic growth, strained public services, and a rising cost of living. A dismal performance in May’s local elections prompted numerous Labour MPs to call for Starmer’s resignation. The appointment of Peter Mandelson as U.K. ambassador to the United States added further controversy. In response, former health secretary Wes Streeting resigned in May, citing a leadership “vacuum.”
Key Players
- Andy Burnham – 56-year-old mayor of Greater Manchester, nicknamed “King of the North,” who has overseen rapid urban regeneration since 2017. He campaigns on “Manchesterism” and criticises “London-centric politics.”
- Keir Starmer – Prime Minister and Labour leader, defending his mandate from the 2024 election and refusing to step down.
- Wes Streeting – Former health secretary and senior Labour MP, prepared to contest the leadership if Starmer does not resign.
- Rob Kenyon – Reform UK candidate, a plumber emphasizing immigration concerns in a constituency with relatively low immigrant numbers.
- Restore – An even more hard-line anti-immigration party competing with Reform UK for the right-wing vote.
Timeline of Recent Developments
- July 2024 – Labour wins a landslide general election.
- May 2026 – Local elections show poor Labour performance; Streeting resigns as health secretary.
- Early June 2026 – Josh Simons steps down, triggering the Makerfield by-election.
- June 9 2026 – Andy Burnham campaigns in Ashton-in-Makerfield, pledging political change.
- June 18 2026 – Articles publish analysis of the by-election’s national significance.
- Thursday (June 20 2026) – By-election held; results expected early Friday.
Electoral Data: Voter Base and Historical Trends
Makerfield has elected Labour MPs for more than a century, reflecting a strong historical loyalty. The constituency’s electorate of roughly 75,000 includes several towns on the edge of Greater Manchester. Recent local polls indicate Reform UK gaining ground in post-industrial northern areas, though precise vote shares are not disclosed.
Official Statements & Responses
Prime Minister Starmer told reporters at a G7 summit that he will “fight if there’s a challenge” and emphasized the 2024 election mandate, insisting he will not “walk away.” He later suggested offering Burnham a senior Cabinet role should the mayor win the seat, though Burnham’s camp reportedly declined. Burnham’s campaign has framed the election as a chance to overturn “London-centric politics” and promised to “change politics” if voters trust him. Streeting publicly urged Starmer to step down, warning that the party faces a “vacuum” without new vision. Reform UK’s Kenyon has highlighted immigration as a key concern for local voters, while the party’s broader surge in northern England is noted by analysts.
Criticism & Opposition
Labour insiders criticize Starmer’s handling of the economy, public-service reforms, and the controversial ambassadorial appointment of Peter Mandelson. Streeting’s resignation underscores internal dissent. Reform UK’s anti-immigration platform faces opposition from centrist voters and from the even more hard-line Restore party, which competes for the same electorate. Political scientists warn that a Reform win could destabilise Labour’s traditional base, while a Burnham victory could accelerate leadership turnover.
Verbatim Quotes

- “where we need vision, we have a vacuum.” — Wes Streeting, Former Health Secretary
- “I will fight if there’s a challenge,” — Keir Starmer, Prime Minister
- “Rob Ford, professor of political science at the University of Manchester, said that if Burnham wins convincingly, “the pressure on Starmer will be very hard to resist.” — Rob Ford, Professor of Political Science, University of Manchester

Conflicting Reports & Gaps
The sources provide no specific polling percentages for Burnham, Starmer, or Reform UK, leaving the exact competitive balance unclear. Additionally, while Reform UK’s recent local-election gains are mentioned, detailed vote counts are absent.
What’s Next
If Burnham secures the Makerfield seat, Labour MPs could rally behind him, meeting the 81-MP threshold to trigger a leadership contest. A successful challenge would likely result in Starmer’s resignation and could see Burnham become prime minister without a general election. Conversely, a Reform or Restore victory would signal a right-wing surge in the north and could force Labour to reassess its regional strategy ahead of the next national election.
