UK Local Elections 2026: Burnham builds a cabinet of his ownBackground
Andy Burnham served as MP for Leigh from 2001 to 2017, held Cabinet posts under Blair and Brown including Health Secretary, and ran unsuccessfully for Labour leader in 2010 and 2015 before leaving Parliament to become Greater Manchester Mayor in 2017, a post he held until 2026.
Josh Simons resigned the Makerfield seat on 14 May 2026 so Burnham could stand and qualify for a Labour leadership contest; the NEC approved his candidacy on 15 May after initially voting against it.
He inherited the Local Government Reorganisation programme days before taking office, with councils already contesting its timetable in the courts and the Local Government Association's new chair publicly asking for it to be adjusted.
Burnham completes an uncontested takeover
Burnham won the Makerfield by-election on 18 June 2026 with 54.8% of the vote, a result that helped prompt Keir Starmer's resignation as prime minister four days later. With no rival clearing Labour's 81-MP nomination threshold, he was confirmed leader at a 17 July special conference without a single member's vote, and took office as prime minister on 20 July.
He finished the reshuffle by 23 July, promoting Healey to the Treasury, Miliband to the Foreign Office and Angela Rayner to Housing, while three of the previous prime minister's loyalists were pushed out of government altogether rather than moved, a sharper break than a routine change of team.
Burnham rules out a second referendum
Burnham told Scottish Labour MPs on 7 July 2026 that no second independence referendum would be authorised, refusing a Section 30 order and offering enhanced devolution instead.
The refusal hardened the line Downing Street had already taken after Holyrood voted to demand a referendum in May, and because only Westminster can make such a vote legally binding, it closes the SNP's route to one for now regardless of Holyrood's own majority arithmetic. It was one of his first substantive policy positions as leader, set before he had even taken office.
His opening bounce splits the pollsters
The first polls taken after Burnham became prime minister disagreed sharply on the size of any bounce. Deltapoll's 17-20 July fieldwork gave Labour a 28% share that pulled it level with Reform, an eight-point jump; YouGov, polling two days on, found almost no movement and kept Reform ahead, 23% to 20%.
By the following weekend a second pollster had put Reform behind for the first time in over a year, though YouGov's own tracker still refused to confirm any shift, leaving Burnham's personal effect on the national polls as contested a fortnight in as it had been on his first day. Labour's Bev Craig then won the Greater Manchester mayoralty Burnham himself had vacated on 30 July, the first electoral test anywhere since he became prime minister, giving him a Labour hold in his own former patch to point to whatever the national polls say.
