Labour’s National Executive Committee cleared Andy Burnham on 15 May to enter the candidate selection process for the Makerfield by-election after the sitting Labour MP resigned to create the vacancy. The contest is scheduled for 18 June, leaving a narrow window for results to be declared before the 30 June market close. Burnham, currently Greater Manchester mayor, is widely expected to secure the nomination at the 21 May selection meeting and enters the race as the frontrunner in a constituency that returned Labour with a 5,399 majority in 2024. Reform UK has signalled an aggressive campaign, adding uncertainty to the outcome. Traders appear to price in a solid but not guaranteed Labour victory, reflecting the seat’s recent history alongside the heightened profile of the contest amid leadership speculation within the governing party.
