How a British prime minister combines executive and parliamentary power

The prime minister leads both the executive and the largest Commons party, combining functions that are separated more sharply in the United States.

Question

Is the British prime minister more powerful than the president of the United States?

Short answer

The powers are structured differently: the prime minister combines executive leadership with control of the largest Commons party.

Notes

The comparison is only a starting point and needs constitutional nuance. A British prime minister heads the executive while also leading the largest party in the House of Commons. In rough American terms, that combines part of a president's governmental position with some of the parliamentary control associated with a House leader. The office is powerful in a different way rather than simply ranking above or below the US presidency.
