Andy Burnham, the current Mayor of Greater Manchester, has been confirmed as the Labour Party’s candidate for the Makerfield by-election, expected to take place on 18 June 2026. The Labour Party’s National Executive Committee (NEC) approved his candidacy without shortlisting any other contenders, following the seat’s vacancy after Josh Simons’ departure. This by-election is seen as a critical step for Burnham, who is positioning himself as a potential successor to Labour leader and UK Prime Minister Keir Starmer .
Burnham is also preparing a 100-day plan for government, should he ascend to national leadership. His team is reportedly focusing on reforms to England’s social care system, among other priorities, as part of this strategy .
In the Makerfield by-election, Burnham will face a challenge from Reform UK, which has selected a candidate—a plumber who came second in the 2024 general election in the same constituency—to contest the seat. This race is seen as a test of Burnham’s political momentum ahead of a potential Labour leadership bid .
Burnham’s stance on Brexit has drawn attention, as he adopts a cautious approach compared to other Labour figures like Wes Streeting, who has openly advocated for rejoining the EU. While Burnham has acknowledged that Brexit was "damaging," he has downplayed the issue in the by-election campaign, framing it as a divisive topic he does not intend to prioritize. His position reflects a broader shift in Labour’s approach, where EU membership is no longer taboo but is not being actively pushed as a policy goal .
Polling among Labour Party members suggests strong support for Burnham as a potential leader. A YouGov survey found that members would prefer Burnham over Starmer if a leadership contest were held, indicating his growing influence within the party. This sentiment has fueled speculation that Burnham could emerge as a key challenger to Starmer, particularly if he secures a seat in Parliament through the Makerfield by-election .
Burnham’s political profile has been bolstered by his reputation as a pragmatic and effective leader in Greater Manchester, earning him the nickname "King of the North" in some media coverage. His potential ascent to national leadership is seen as a significant development in UK politics, particularly amid Starmer’s declining popularity .
