Keir Starmer has announced his resignation as prime minister of the United Kingdom and leader of the Labour Party, ending his tenure at Downing Street.

The announcement, made on Monday, confirms reports that had circulated over the weekend regarding his imminent departure from office.

Starmer stated that the role had been the most important job in the country, but he intends to focus on what he described as the most important role in his life.

The abrupt exit creates a power vacuum in the UK government, triggering immediate questions about the stability of the current administration and the timeline for a new leadership election.

Markets are reacting to the heightened political uncertainty, with sterling showing increased volatility against major trading partners.

Investors are closely watching for signs of policy continuity or disruption as the Labour Party prepares to select a successor.
