Sir Keir Starmer delivered his final address as Prime Minister and formally handed power to Andy Burnham on Monday [1].

The transition marks a significant shift in leadership for the Labour Party and the United Kingdom after Starmer lost the party leadership to Burnham [1].

Standing at Number 10 Downing Street in London, Starmer spoke to the nation before the formal handover [2]. He reflected on his tenure and the conclusion of his leadership role. "My work is done," Starmer said [2]. He said that he had "closed the book" on his time as Prime Minister [3].

Following the farewell address, Andy Burnham was sworn in as the new Prime Minister [1]. The transition occurred on July 20, 2026 [1]. Burnham, who previously led the Labour Party, took the oath of office to begin his term at the head of the British government.

In his first comments as the new leader, Burnham signaled a desire for a departure from previous strategies. "This is a circuit breaker," Burnham said [3].

The transfer of power follows a scheduled transition after the leadership contest within the Labour Party. The event concludes Starmer's time at the residence of the Prime Minister, a symbolic end to his administration's period of governance [1, 2].

"My work is done."

The transition from Sir Keir Starmer to Andy Burnham represents an internal pivot within the Labour Party. By describing the change as a 'circuit breaker,' Burnham suggests a strategic break from the previous administration's approach to governance and policy, potentially signaling a shift in how the party engages with the electorate and manages the UK's domestic priorities.
