Liz Truss becomes new UK prime minister

Foreign Secretary will replace Boris Johnson in top office

British Foreign Secretary Liz Truss has been chosen to lead the Conservative Party and become the new prime minister.

The winner of the two-month race between Truss and former finance minister Rishi Sunak was announced on Monday by Sir Graham Brady, chair of the 1922 Committee of backbench Tory MPs.

Around 160,000 Conservative party members voted in the final stage of the contest, which closed on Friday.

Truss will replace Boris Johnson at 10 Downing Street. Johnson announced his resignation on July 7 after a series of high-profile scandals and cabinet resignations.
