List all the Presidents of United Kingdom up to date?

The United Kingdom does not have a President; instead, it has a Prime Minister as the head of government. The monarch serves as the head of state. The Prime Minister's role has been occupied by various individuals since the office was established, with notable figures including Winston Churchill, Margaret Thatcher, and Tony Blair. As of my knowledge cutoff in October 2023, Rishi Sunak is the current Prime Minister.
