The Prime Minister of the United Kingdom (informally abbreviated to PM) is the head of government of the United Kingdom and the foresitter of the cabinet. The Prime Minister directs both the law-doing (Cabinet) and the law-making (Rikesday) bodies of the United Kingdom. Together with the rest of Cabinet, the Prime Minister is responsible to the monarch, to Rikesday, to their party, and ultimately to the voters, for the government's policies and actions.

The office of Prime Minister is not established by any law set but exists only by long-established wonelaws, whereby the reigning monarch appoints as Prime Minister the person most likely to command the confidence of the Folkthing; this person is typically the leader of the political party or coalition of parties in the thing which wins most seats after a general election.  The position of Prime Minister was not created; it evolved slowly and organically over three hundred years due to numerous parliamentary sets, political developments, and accidents of history.

By the 1830s, the Westminster system of government (or cabinet government) had emerged; the prime minister had become primus inter pares or the first among equals in the Cabinet and the head of government in the United Kingdom. The political position of Prime Minister was enhanced by the development of modern political parties, the introduction of mass communication and photography. By the start of the 20th century the modern premiership had emerged; the office had become the pre-eminent position in the constitutional hierarchy alongside the King/Queen, Rikesday and Cabinet.

After 1902, the Prime Minister rarely but sometimes comes from the Athelthing, provided that his/her government could form a majority in the Folkthing. Nevertheless, as the power of the athelings waned during the 19th century, the Prime Minister who comes from the Althelthing usually holds lesser authority compared with the one who sits as a Fellow of Day (FD) in the lower house. An atheling who serves as prime minister can sits together with Fellows of Day from his/her party in the Folkthing, but has no voting right. The Prime Minister who serves as the leader and a Fellow has further authority in the law-making process, enhanced by the Rikesday Set 1911 which marginalized the influence of the athelings.

The prime minister is ex officio also First Lord of the Gavelgild and Minister for the State’s Rareknack. Indeed, certain privileges, such as residency of 10 Downing Street, are accorded to prime ministers by virtue of their position as First Lord of the Gavelgild. The status and law-doing powers of the British prime minister means that the incumbent is consistently ranked as one of the most powerful democratically elected leaders in the world.
