Who was the leader of the converative party?

As of my last update in October 2023, the leader of the Conservative Party in the United Kingdom was Rishi Sunak. He became the leader in October 2022, succeeding Liz Truss after her brief term. Sunak also serves as the Prime Minister, having previously held the position of Chancellor of the Exchequer. Please verify with up-to-date sources, as political leadership can change frequently.
