Andy Burnham's recent clearance by Labour's National Executive Committee to enter the candidate selection process has solidified his position as the leading contender in the Makerfield by-election set for June 18. The resignation of incumbent Labour MP Josh Simons was explicitly intended to open the seat for the Greater Manchester mayor, highlighting internal party efforts to capitalize on Burnham's established local profile and personal popularity across the constituency. Recent local election results indicate strong Reform UK performance in the area, boosting Robert Kenyon's prospects as the main challenger, though traders view Burnham's brand as providing Labour with a decisive edge in this closely watched contest. Other declared candidates trail significantly with limited visibility.
