The upcoming byelection for Greater Manchester mayor, set for July 30, is poised to be the largest in British history, with over 2 million eligible voters. This election will serve as a critical indicator of public sentiment towards the main political parties, particularly Labour and Reform UK, following significant recent electoral shifts.
Andy Burnham's successor will be determined through a supplementary voting system, raising questions about the viability of Reform UK and the Green party in capturing second-choice votes. Political analysts suggest that Labour's support may be declining, which could impact the party's future leadership and strategy.
