Andy Burnham Announces Leadership Challenge Ahead of Makerfield By-Election
6/5/2026, 4:50:24 AM
The Challenge Unveiled
On 2 June, Greater Manchester mayor Andy Burnham told a BBC Question Time audience in the Makerfield constituency that, if elected MP on 18 June, he would seek to join any Labour leadership contest against Prime Minister Sir Keir Starmer. Burnham stressed that his bid depends on winning the seat and on persuading a majority of the Parliamentary Labour Party (PLP) to back him. He framed the move as a response to what he described as “fundamental change” needed in Westminster.
Background to the By-Election
The by-election was triggered after Labour MP Josh Simons stepped down to allow Burnham to contest the seat. Makerfield, part of Greater Manchester, voted for Brexit in 2016 and saw Reform UK win all eight wards in the previous local elections, securing a 50 % vote share. The contest pits Burnham against Reform UK candidate Robert Kenyon, a plumber and local councillor, with additional candidates from the Conservatives, Greens, Liberal Democrats and Restore Britain.
Key Players
- Andy Burnham – Greater Manchester mayor, Labour candidate.
- Sir Keir Starmer – Labour leader and Prime Minister.
- Wes Streeting – Former health secretary, cited by Burnham as having “launched a leadership contest”.
- Robert Kenyon – Reform UK candidate, criticised for past social-media comments.
- Michael Winstanley – Conservative candidate, called for Starmer’s removal.
- Rebecca Shepherd – Restore Britain candidate, polling at 8 % (Survation).
Timeline of Recent Developments
- 2 June – Burnham’s Question Time appearance, leadership intent announced.
- 4 June – Reuters reports Burnham’s conditional challenge and low Labour poll standings.
- 5 June – Survation poll shows Burnham 49 % vs Kenyon 39 % among voters.
- 18 June – Scheduled Makerfield by-election.
Data & Statistics
- Survation poll (n = 518): Burnham 49 %, Kenyon 39 %, Shepherd 8 %, Wakefield 2 %, Lib Dem 1 %, Conservative 1 %.
- Reform UK captured 50 % of the vote in the eight-ward local election preceding the by-election.
Why It Matters
A Burnham victory would give him the parliamentary platform required to trigger a formal leadership challenge, potentially reshaping Labour’s policy direction on social care, immigration and fiscal reform. It also tests Labour’s internal cohesion, as the PLP must endorse any challenger. The outcome could influence the party’s standing ahead of the next general election.
Official Statements & Responses
- Downing Street: “The Labour Party has a process for challenging a leader and it has not been triggered. The Prime Minister will not walk away from the mandate he was given two years ago.”
- BBC: Explained that only five panelists were selected for the Question Time debate based on recent electoral support, noting the impossibility of inviting every candidate.
- Burnham: Said he would review the exemption allowing Sikhs to carry ceremonial knives and would bring forward the Casey review of social-care funding to be published by the end of 2026. He also ruled out calling a snap general election if he became prime minister.
Criticism & Opposition
Kenyon faced renewed scrutiny over historic online remarks on women, Brexit and abortion, which he described as “mistakes”. Conservative candidate Michael Winstanley labelled the by-election “foisted” on voters and pledged to “get rid of Keir Starmer” regardless of the winner. Burnham’s record as mayor was challenged by Kenyon, who argued that while Manchester “thrives,” Wigan “struggles to survive.”
On-the-Ground Reactions
Audience members at the Question Time special linked Kenyon’s past comments to broader concerns about “career politicians” versus “local people”. Protests erupted in Southampton after the murder of 18-year-old Henry Nowak, a case Burnham referenced when discussing possible review of knife-carrying exemptions.
Conflicting Reports & Gaps
Burnham hinted that a different Brexit outcome might have occurred under his leadership, but did not complete the statement, leaving his exact position ambiguous. Sources differ on whether a formal leadership challenge process has been activated; Downing Street insists it has not, while Burnham’s comments suggest he will seek PLP backing.
