Sir Keir Starmer has announced he will stand down as the Member of Parliament for Holborn and St Pancras, saying he intends to concentrate on work in international affairs and on combating violence against women and girls. The surprise declaration will force a by-election in a seat he has held since 2015.
Immediate political impact
The resignation comes weeks after he left Downing Street in July and follows speculation about whether he would remain in Parliament until the next general election. He had previously indicated he would stay on as an MP until the next nationwide poll, which is not due until 2029, but his statement to the Camden New Journal said now was the right time to "pass the baton to a successor".
"I will now focus on other things and that will be international affairs including defence, security, trade and technology in a fast-changing world. I will also continue... to work on combating violence against women and girls; that is an issue that matters to me hugely."
The decision places the Labour Party on the cusp of a by-election contest in a constituency regarded as a Labour stronghold. Holborn and St Pancras has been represented by Sir Keir since he first won the seat in 2015.
Reaction inside Parliament
Andy Burnham, who succeeded Sir Keir as prime minister and made his first appearance in the House of Commons after the announcement, paid tribute to his predecessor. He highlighted Sir Keir's involvement with Ukraine and the introduction of the Hillsborough Law that was developed under his government to improve accountability among public officials, noting the legislation is currently progressing through Parliament.
Burnham described Sir Keir as a public servant who "gave this country a lifetime of public service, particularly for those fighting for justice," and said his leadership had transformed the Labour Party's electoral fortunes.
What Sir Keir says he'll do next
In his statement Sir Keir set out two principal areas of focus for his post-Parliament work: international affairs — including defence, security, trade and technology — and continuing long-standing campaigns against violence towards women and girls. He said that alongside others he has worked for some time on the latter issue and intends to pursue it after leaving the Commons.

Wider consequences and context
The departure of a former prime minister from the Commons is a notable political event. It will prompt a by-election campaign in a central London seat that Labour has held for a decade, giving opposition parties an opportunity to test electoral strength on a national stage. The episode also reframes Sir Keir’s public role: rather than maintaining a parliamentary presence as a backbencher, he has chosen to move into work that is outward-facing and international.
- By-election: a contest will be called for Holborn and St Pancras, with parties selecting candidates to contest the seat.
- Labour leadership dynamic: the party will need to manage candidate selection and the message around the former leader’s exit while consolidating behind the new prime minister.
- Policy focus: Sir Keir’s stated priorities — defence, security, trade and technology, and violence against women and girls — indicate the areas he is likely to engage with outside Parliament.
As the by-election timetable is set and potential candidates emerge, attention will centre on whether Labour can retain the seat comfortably and what the result may signal about public appetite for the government led by Andy Burnham. Meanwhile, Sir Keir’s pivot to international work and campaigning on gendered violence suggests he will remain a prominent public figure despite leaving the Commons.
