In a surprise appointment, Cameron was named foreign secretary after Prime Minister Rishi Sunak sacked hard-line Interior Minister Suella Braverman and replaced her with foreign secretary James Cleverly, in his first cabinet reshuffle since taking office last October.

Cameron said he hoped his experience as prime minister from 2010 to 2016 would help him deal with current challenges internationally.

"While I have been out of front-line politics for the last seven years, I hope that my experience – as Conservative Leader for eleven years and Prime Minister for six – will assist me in helping the Prime Minister to meet these vital challenges,” he said in a statement published on X after his appointment.

Cameron, who resigned the day after the referendum that ended Britain’s membership with the European Union, has spent the seven years since writing his memoirs and pursuing business interests.

Sunak’s ruling Conservative Party is lagging behind the Labour party ahead of an election expected next year.

Cameron's return, and Braverman's removal, angered some on the right of the party, though more centrist Tories welcomed Cameron’s appointment, saying his international experience will help steady the ship.
