Andy Burnham was sworn in as the prime minister of the United Kingdom on July 12, 2026 [4].
The leadership change follows the resignation of Keir Starmer, marking a period of significant political instability for the nation. This turnover underscores a decade of frequent transitions at 10 Downing Street, where leadership has shifted rapidly across different parties and platforms.
Burnham officially took office after a ceremony in the presence of King Charles III [2]. The transition occurred as Keir Starmer formally resigned his position following a meeting with the monarch [3].
Burnham is the seventh prime minister to serve the UK in 10 years [1]. This streak of leadership changes includes various tenures of differing lengths. For example, Boris Johnson held the post for three years [2], while Liz Truss served for 49 days [3].
Reports indicate the Labour Party appointed Burnham as the successor to Starmer amid this ongoing cycle of political turnover [5]. The shift in leadership was finalized as Starmer left 10 Downing Street to make way for the new prime minister [2].
"Andy Burnham was sworn in as the new prime minister on July 12," a Global News reporter said [4].
"Outgoing leader Keir Starmer has now formally resigned as UK prime minister after a meeting with King Charles III," a CNN correspondent said [3].
"British Prime Minister Keir Starmer leaves 10 Downing Street, as his successor Andy Burnham takes office," an NPR reporter said [2].
“Andy Burnham is the United Kingdom's seventh prime minister in 10 years.”
The appointment of Andy Burnham as the seventh prime minister in a decade highlights a persistent volatility in British governance. By cycling through seven leaders in 10 years, the UK has struggled to maintain long-term policy continuity, moving from the three-year tenure of Boris Johnson to the brief 49-day term of Liz Truss. Burnham now inherits a political landscape defined by this instability, and the challenge of establishing a durable mandate following Keir Starmer's resignation.
