• Former PM Keir Starmer resigns from parliament to pursue international affairs.
• Starmer steps down after 11 years as MP, triggering a by-election.

Former UK Prime Minister Keir Starmer announced his resignation from parliament to concentrate on “international affairs,” including defence, security, trade, and technology. He stated it was the “right time” to step down as the MP for Holborn and St Pancras after 11 years, triggering a by-election, according to SCMP and Le Monde.

This decision follows Starmer's resignation as party leader amid internal pressures within the Labour Party. Andy Burnham has since been appointed Prime Minister. Starmer had previously considered remaining in parliament until the next general elections but has altered his plans, indicating a definitive shift towards international issues, according to Al Jazeera and SCMP.

During his leadership, Starmer played a pivotal role in revitalizing the Labour Party, leading it to a historic landslide victory in 2024. However, a series of missteps and contention from within the party weakened his authority, culminating in his resignation under pressure from Labour MPs, as noted by Le Monde and Al Jazeera.

Despite waning domestic popularity, Starmer's experience in foreign affairs is noted, particularly his relationships with EU leaders during Brexit. This includes cooperation with French President Emmanuel Macron, aimed at supporting Ukraine against Russian aggression, observing Al Jazeera and SCMP.
