LIZ TRUSS, the prime minister of the United Kingdom (UK), resigned Thursday.

With only a little over six weeks in office, she became the shortest-serving prime minister in U.K. history. She sworn in as British prime minister Sept. 6.

Truss made the announcement a day after she defiantly declared that she is “a fighter and not a quitter.” Ultimately, however, she said that circumstances have changed.

“Given the situation, I cannot deliver the mandate on which I was elected by the Conservative Party,” Truss said. “I have therefore spoken to His Majesty the King to notify him that I am resigning as leader of the Conservative Party.”

Truss said that a leadership election will take place “within the next week” and that she will stay on as prime minister “until a successor has been chosen.”

Truss’ announcement came soon after Home Secretary Suella Braverman resigned via a letter that slammed the prime minister.

“The business of government relies upon people accepting responsibility for their mistakes,” Braverman said. “Pretending we haven’t made mistakes, carrying on as if everyone can’t see that we have made them and hoping that things will magically come right is not serious politics.”

Braverman, part of the right wing of the Conservative Party, ran for party leader earlier this year, coming up short when Truss won.

Braverman’s exit came days after Truss fired Treasury head Kwasi Kwarteng amid financial turmoil that included the British pound declining in value to be nearly equal to the U.S. dollar. The problems came after Truss’ administration pushed a tax cut plan in September, which Kwarteng’s replacement Jeremy Hunt scrapped in October.

Truss apologized to lawmakers Wednesday and admitted she had made errors during her time in office but insisted that scrapping the tax cut plan was “the right decision.”
