Andy Burnham, the mayor of Greater Manchester, is positioning himself for a potential return to Westminster and a bid to become leader of the Labour Party and, ultimately, prime minister. His immediate political test will be the forthcoming by-election in Makerfield, a constituency south of Wigan, where Labour recently suffered significant losses to Nigel Farage’s Reform UK party in local elections. Winning this seat, where Labour has historically held strong but now faces eroding support, is viewed as critical to Burnham’s leadership ambitions.

Burnham, 56, has been a prominent figure in British politics for over two decades, first elected as a Member of Parliament in 2001 and serving in Gordon Brown’s cabinet, including as health secretary. After unsuccessful Labour leadership bids in 2010 and 2016, he reemerged as Greater Manchester’s metro mayor in 2017, a role that has allowed him to cultivate a new political identity rooted in regional devolution and economic development. His stewardship coincided with strong economic growth in Manchester, outperforming the national rate, and notable local achievements such as the public takeback and modernization of the city’s bus network. At the same time, critics question whether some successes are continuations of earlier policies rather than new initiatives. Housing remains a challenging area; a campaign pledge to build 10,000 homes by 2028 has faced setbacks and controversies, including debates over public loans to developers.

Central to Burnham’s leadership platform is what he calls “Manchesterism,” a political philosophy advocating greater devolution of power from Westminster to local authorities and mayors, alongside increased public investment in infrastructure. He has proposed a significant expansion of public ownership, including energy, water, and rail sectors, reflecting his intent to "roll back the 1980s." Economically, Burnham rejects current fiscal constraints and argues for higher borrowing to fund public spending. His tax proposals include introducing a 10 percent starting income tax rate for lower earners and raising the top rate to 50 percent, combined with regional adjustments such as higher council taxes in London and the southeast.

On social issues, Burnham supports trans rights and criticizes legislation that defines sex strictly by biology. He advocates for integrated health and social care services under greater local control, citing improved outcomes in Greater Manchester following devolution. Although supportive of enhanced border security measures, he has expressed concern about policies that might leave migrants in uncertain situations. Burnham is also a proponent of constitutional reforms, including replacing the first-past-the-post electoral system with proportional representation, abolishing the House of Lords in favor of a Senate of the Nations and Regions, and weakening rigid party discipline in Parliament.

The by-election in Makerfield highlights some of the challenges Burnham faces. The area, with a significant leave vote in the 2016 Brexit referendum and an average income near the national median, has seen rising local support for Reform UK, driven by dissatisfaction with both Labour and Conservative parties. Local voters express concerns about immigration, public safety, and economic neglect, with some perceiving Labour as disconnected from the working-class base. Reform UK, buoyed by recent victories, has promised an intense campaign to retain its momentum.

Within Labour, many see Burnham’s “king of the north” image and outsider status as advantageous in challenging Sir Keir Starmer’s leadership. However, some observers question whether his record as mayor adequately prepares him for national leadership and whether his policy positions can unify the party while appealing to broader electorates. His choice of key cabinet members, including potential chancellor candidates such as Wes Streeting or Ed Miliband, and prominent roles for Angela Rayner and Lucy Powell, will be closely watched as indicative of his governing style and priorities.

As the contest for Makerfield approaches, Burnham’s campaign embodies both the hopes and uncertainties facing Labour. His ability to convert local protest votes into support may well determine not only his personal political trajectory but the future direction of the party.
