The By-Election Stakes
The Labour National Executive Committee (NEC) has cleared Greater Manchester mayor Andy Burnham to stand in the Makerfield by-election on 18 June after MP Josh Simons resigned to make way for him. A victory would return Burnham to the Commons and give him the statutory right to challenge Prime Minister Sir Keir Starmer for the Labour leadership.
Background & Context
Makerfield has been a Labour seat since its creation in 1983. In the 2024 general election Simons held it with a 5,399-vote majority over Reform UK. Local elections later that month saw Reform win every council ward, securing ?50 % of the vote while Labour fell to just over 25 % (sources 34, 44, 46). The constituency voted 65 % Leave in the 2016 EU referendum (source 40).
Key Figures & Groups
- Andy Burnham – mayor, net favourability 24 % (Ipsos) and 35 % positive opinion (YouGov).
- Sir Keir Starmer – Prime Minister, insists he will not set a timetable to step down.
- Wes Streeting – former health secretary, resigned from cabinet, backs Burnham for the seat but says he will stand in any leadership contest.
- Lucy Powell – Deputy Leader, pledged full support for Burnham’s candidacy.
- Reform UK – led by Nigel Farage, positioned as the main challenger.
- Green Party – also fielding a candidate, though polling suggests limited impact.
Data & Statistics
- Survation: Labour’s chance of winning with Burnham as candidate 67 %; without him 0 % (source 13).
- Sir John Curtice: Labour would have “less than 5 % chance” of retaining the seat without Burnham (source 14).
- By-election cost: up to £226,000 for the poll; a subsequent mayoral by-election could cost several million (sources 15, 38).
Official Statements & Responses
- Starmer told broadcasters: “I’m not going to set a timetable to stand down” and affirmed 100 % backing for whichever Labour candidate is selected (sources 9, 1).
- Burnham announced his aim to “make life more affordable again… power up places… re-industrialise” and framed the vote as a chance to “change Labour” (source 9).
- The NEC confirmed it would not block Burnham’s selection, citing procedural fairness (source 48).
- Reform UK leader Farage pledged to “throw everything” at the contest (source 6).
Criticism & Opposition
- Deputy Prime Minister David Lammy warned that internal moves risk “scoring a spectacular own goal”.
- Housing Secretary Steve Reed cautioned that a leadership contest could further damage Labour’s electoral prospects.
- Streeting’s pro-EU remarks have been described by Burnham allies as “sabotage” that could hand Reform a potent campaign line (source 40).
- Right-wing figures, including Jacob Rees-Mogg, urged a tactical alliance between Conservatives and Reform to block Burnham (source 32).
On-the-Ground Reports
Labour MPs visiting Makerfield described the race as “really, really, really tough” and expressed personal anxiety about a potential loss (sources 16, 50). Local activists note Burnham’s long-standing ties to the area, but acknowledge the constituency’s recent shift toward Reform (source 17).
Conflicting Reports & Gaps
- Sources differ on the exact cost of the by-election (£226,000 vs. £226,208).
- Burnham’s stance on EU re-membership is reported both as “not proposing a re-join” (source 10) and as a point of contention exploited by opponents (source 40).
- Precise Reform vote share in the latest local elections varies between “around 50 %” and “just over half” across reports.
Verbatim Quotes

- “And that means having Andy Burnham as a key player in that team, in my view.” — Lucy Powell, Deputy Leader.
- “Andy is the best chance of winning and that should override factional advantage or propping up one person.” — Wes Streeting, tweet.

What’s Next
