British Prime Minister Keir Starmer has submitted his resignation, ending his tenure as head of government and leader of the Labour Party.

The announcement confirms reports that had circulated over the weekend regarding his imminent departure from Downing Street, marking a sudden shift in the UK's political landscape.

The resignation follows mounting pressure within the Labour Party, with reports indicating Starmer had lost support among key factions.

US President Donald Trump previously commented on the situation, suggesting that disputes over immigration and energy policy were central to the leadership crisis.

The abrupt nature of the departure suggests internal party dynamics had reached a breaking point.

Markets are likely to monitor the situation closely for signs of policy continuity or disruption.
