Former UK PM Starmer Walks Away from Parliament as London By-Election Looms

Former British Prime Minister Sir Keir Starmer is stepping down as the Member of Parliament for Holborn and St Pancras, bringing his 11-year representation of the north London constituency to an end and triggering a by-election.

Starmer announced the decision on Tuesday, saying he had concluded that it was the right time to leave the House of Commons and redirect his attention towards international affairs.

The former Labour leader has represented Holborn and St Pancras since 2015 and served as Prime Minister from July 2024 until July 2026.

His decision comes just weeks after he resigned as prime minister on July 20, when Andy Burnham succeeded him as Labour leader and head of government.

Starmer’s departure will now force a by-election in Holborn and St Pancras, a traditionally safe Labour seat that he won at the 2024 general election with a majority of more than 11,000 votes.

The move marks a significant change from Starmer’s earlier plan to remain in Parliament as a backbench MP after leaving Downing Street. Reports at the time of his resignation indicated that he intended to serve out the remainder of his parliamentary term.

Starmer said his future focus would include international affairs, particularly areas such as defence, security, trade and technology, while continuing work on tackling violence against women and girls.

His resignation is expected to provide an early electoral test for Burnham’s new Labour government, with opposition parties already considering the possibility of contesting the London seat.

The announcement also marks the end of Starmer’s parliamentary career for the time being, following more than a decade at Westminster and his rise from opposition leader to prime minister after Labour’s landslide victory in the 2024 general election.
