Andy Burnham has secured a decisive victory in the Makerfield by-election, winning with a majority of 9,231 votes and capturing 54.8 percent of the vote share. While the win reinforces Burnham’s strong local standing, it signals growing tensions within the Labour Party and foreshadows potential political turmoil at the national level.

Burnham’s triumph reflects widespread dissatisfaction among constituents, driven in part by an anti-Keir Starmer sentiment and concerns over the deteriorating economic situation. However, analysts suggest that the vote was less an endorsement of Labour’s current leadership and more a personal mandate for Burnham, who is positioning himself as a prominent challenger to Starmer's authority. The result has intensified speculation about a looming leadership contest within Labour, which could ignite internal divisions.

Despite Burnham’s call for unity and reform, Labour is expected to face weeks of infighting and debate over policy direction if Starmer remains in place. Some party members anticipate a shift toward more left-leaning, high-spending welfare policies, which have reportedly resonated with parts of the electorate but also raised concerns among workers and business interests about affordability and economic impact.

The by-election outcome also highlighted the evolving dynamics on the right. Reform UK, which had recently surged in local council elections throughout the Wigan area, capturing nearly all council seats, failed to meet expectations this time, garnering 34.5 percent of the vote. Their candidate, Robert Kenyon, faced criticism over prior allegations of misogyny, a factor that likely hindered his appeal among women voters. Campaign efforts by activist group Stand Up to Racism aimed at spotlighting these issues may have further dampened support for Reform UK.

Restore Britain captured 6.8 percent, dispelling earlier concerns that it would split the Eurosceptic vote and threaten Labour’s hold on the seat. Meanwhile, combined support for the other major parties—Conservatives, Greens, and Liberal Democrats—totalled just around 3 percent.

In Scotland, the Scottish Conservatives scored a notable win, reclaiming the Aberdeen South Westminster seat from the Scottish National Party for the first time in over five decades. The Tory candidate, Douglas Lumsden, attributed his success to campaigning on local economic priorities, notably advocating for North Sea oil and gas exploration.

Burnham has urged Labour to seize “a final chance to change,” promising a “new politics based on unity and hope” focused on revitalising the country and addressing regional disparities, particularly through devolving more power to the North of England. However, he has yet to outline a detailed vision for how these promises will translate into policy.

With political fault lines deepening, the UK faces an uncertain period marked by internal party battles and shifting voter allegiances, suggesting the coming months will bring significant upheaval.
