Britain’s Conservative Party has chosen Foreign Secretary Liz Truss as the party’s new leader, putting her in line to be confirmed as prime minister.

Truss’s selection was announced Monday in London after a leadership election in which only about 170,000 dues-paying members of the Conservative Party were allowed to vote.

Truss beat rival Rishi Sunak, the government’s former Treasury chief.

She faces immediate pressure to deliver on her promises to tackle a cost-of-living crisis walloping the U.K. and an economy heading into a potentially lengthy recession.

Queen Elizabeth II is scheduled to formally name Truss as Britain’s prime minister on Tuesday.
