UK Prime Minister Keir Starmer Resigns Amid Labour Party Leadership Shift

Sir Keir Starmer announced his resignation as Prime Minister, stating that confidence in his leadership had been "shaken sufficiently" to justify stepping down, according to Labour ally Baroness Jenny Chapman. Chapman highlighted achievements such as reduced small‑boat crossings, lower immigration, rising wages, falling inflation and interest rates, and a Labour majority of over 150 seats.

Commentators have criticised Starmer’s tenure, saying promises on tax, public ownership, tuition fees and immigration policy were not fulfilled and that internal party discipline tightened under his leadership. The resignation triggers a leadership contest within Labour to select a new Prime Minister.

The transition is expected to shape the next general election and the direction of UK governance.
