FactTreaties, membership, measured data, events.

UK prime minister since July 20, 2026, a former Greater Manchester mayor who replaced Keir Starmer as Labour leader.

The picture

Born in 1970, Burnham was a Labour MP from 2001 and health secretary under Gordon Brown, lost leadership races in 2010 and 2015, then became Greater Manchester's mayor in 2017. After Labour's heavy losses in May 2026, he returned to Parliament by winning the Makerfield by-election in June with 55%, beating Reform UK. Starmer said he would step down; Burnham won the backing of about 80% of Labour MPs and faced no serious challenger. He is seen as softer-left, favoring public control of transport.

Why it matters

He leads a nuclear power and Ukraine's key European backer amid tight public finances and a Reform UK surge that threatens Labour.

Record

The official Makerfield by-election result, Labour Party announcements and the July 20, 2026 royal appointment; his mayoralty is well documented.

What to watch

Outlook: he once said Labour should not be 'in hock to the bond markets'; whether he loosens fiscal rules, and how markets react, is open.
