Liz Truss announces resignation as British prime minister

U.K. Prime Minister Liz Truss announced her resignation on Thursday after less than two months in office.

She replaced former Prime Minister Boris Johnson in September.

Her resignation comes amid heightened economic stress in the U.K. following Russian President Vladimir Putin's invasion of Ukraine.

"I came into office at a time of great economic and international instability," she said during her resignation speech Thursday in front of 10 Downing Street.

"Given the situation, I cannot deliver the mandates on which I was elected by the Conservative Party," Truss said.

She has informed King Charles of her resignation. The Conservative Party will hold a leadership election for her replacement within the next week. Truss plans to remain in office until a successor is chosen.
