Andy Burnham Wins Makerfield By-Election, Launches Challenge to Starmer

Greater Manchester Mayor Andy Burnham has won the Makerfield by-election with a decisive 9,231-vote majority, immediately launching a bid to oust Prime Minister Sir Keir Starmer. Burnham secured 54.8% of the vote, outperforming polls and beating Reform UK’s Rob Kenyon (34.5%).

Burnham's Victory Speech

In his victory speech, Burnham thanked supporters and praised Josh Simons, who resigned to allow him to stand. He said: “We’ve got to now take this moment to answer the challenges that have been laid down.” Burnham called for an economy that “works for everybody,” reducing energy, water, and train fares, and ending “trickle-down economics.” He criticized the education system for being “dominated by the university route” and emphasized getting people into work.

Leadership Challenge

Burnham’s win triggers a potential Labour leadership contest. He thanked campaign staff and noted the campaign was “won by a band of strong northern power women.” Sir Keir Starmer said he would “stand” if a contest is triggered, warning that a leadership race would “plunge us into chaos.” Cabinet ministers like Lisa Nandy and Steve Reed urged unity, while Wes Streeting called Burnham’s win “proof that Labour must change.”

Reactions and Analysis

Union leaders demanded Starmer step down. Sharon Graham of Unite said: “Keir Starmer must do the right thing and step down.” Angela Rayner congratulated Burnham, saying Makerfield “voted for hope.” Polling expert Sir John Curtice warned Burnham’s success may not be replicated nationwide, noting his unique appeal as both a traditional Labour figure and anti-Starmer candidate.

Other By-Election Results

The Conservatives won Aberdeen South from the SNP, their first Scottish by-election gain since 1967. The SNP held Arbroath and Broughty Ferry. Boris Johnson hailed the Aberdeen win as showing “the advantage of campaigning with a clear economic message.”
