Andy Burnham Wins Macclesfield By-Election in Landslide, Fueling Speculation Over Labour Leadership Challenge

Andy Burnham secured a commanding victory in the high-profile Macclesfield by-election, a result that is expected to intensify speculation about a potential challenge to Prime Minister Keir Starmer's leadership of the Labour Party.

The former Mayor of Greater Manchester defeated Reform UK candidate Robert Kenyon by a margin of 9,231 votes. The newly formed right-wing party Restore Britain finished a distant third.

According to the results, Labour won 54.8 percent of the vote, while Reform UK secured 34.5 percent and Restore Britain received 7 percent. Voter turnout reached 58.75 percent, more than six percentage points higher than in the previous general election, with a total of 45,510 ballots cast.

In his victory speech, Burnham described the outcome as a potential turning point in British politics.

“People have voted for change, for greater power in the North of England, and for communities that have long been overlooked by Westminster,” he said. He characterized the result as Labour's “last chance” to deliver meaningful change, warning that there would be no second opportunity.

“Tonight’s result offers a chance to build a new politics based on unity and hope, one that can keep Britain away from the kind of divisive politics seen elsewhere,” Burnham added.

Following what many observers have described as one of the most significant by-election results in modern British political history, speculation is mounting that Burnham could seek the Labour leadership should a formal contest emerge in the coming months.

Burnham reportedly received more than 6,100 votes above the combined total of both Reform UK and Restore Britain, strengthening his standing among Labour MPs and party members.

Prime Minister Keir Starmer congratulated Burnham on the victory, saying voters had chosen Labour’s message of hope and optimism over “division and hatred.”

Political analysts suggested that Burnham benefited from broad anti-Reform tactical voting. The Conservative Party, Liberal Democrats, and Green Party collectively secured just 3 percent of the vote. In the 2024 general election, those parties had won a combined 22 percent in the constituency.

Known as the “King of the North,” Burnham first entered Parliament 25 years ago and served in the governments of former prime ministers Tony Blair and Gordon Brown. His election to Parliament now creates a vacancy in the office of Mayor of Greater Manchester, setting the stage for another closely watched electoral contest in which Labour may face a strong challenge from Reform UK.

The mayoral by-election, involving an electorate of approximately two million voters, is expected to take place on July 30 and is likely to become one of the largest local electoral contests in recent British history.

The Macclesfield by-election was triggered after former Labour MP Josh Simons agreed to step down last month, allowing Burnham to contest the seat and potentially position himself as an alternative figure within the party amid growing concerns over Starmer’s leadership.

Calls for Starmer’s resignation have intensified in recent months following the controversial appointment of Peter Mandelson as the United Kingdom’s ambassador to the United States, Labour’s loss of more than 1,200 local council seats in May elections, and the party’s loss of control of the Welsh Senedd.

Despite the pressure, Starmer has insisted that he has no intention of resigning and remains prepared to face any leadership challenge.

Cabinet Minister and Wigan MP Lisa Nandy described Burnham’s victory as “history-making,” while former Cabinet Minister Louise Haigh, a close ally of Burnham’s campaign, expressed hope that Starmer would ultimately do what is best for both the country and the Labour Party.

The result also represents a significant setback for Reform UK. In local elections held last month, the party won nearly every council ward in the Macclesfield area with close to half of the vote, while Labour secured only around a quarter.

Burnham’s decisive victory in the by-election, however, suggests that Labour has succeeded in rebuilding support within one of its traditional political heartlands and reasserting its electoral strength against rising challengers.
