The office of Prime Minister of Great Britain was established in May 1721 when the former office of Chief Minister of Great Britain was renamed. The Prime Minister of Great Britain (informally abbreviated to PM) was the head of government of the Kingdom of Great Britain. The prime minister directs both the executive and the legislature, and, together with the Prime Minister's Cabinet, (consisting of all the most senior ministers, most of whom are government department heads), is accountable to the monarch, to Parliament, to the prime minister's political party and, ultimately, to the electorate for the policies and actions of the executive and the legislature
The origin of the office of Prime Minister of Great Britain evolved from the office of Chief Minister of England. In May 1707 following the Act of Union between the Kingdom of England and the Kingdom of Scotland thus creating the Kingdom of Great Britain the offices of Chief Ministers for England and Scotland were unified to create the office of Chief Minister of Great Britain. In 1721 the chief minister was renamed to Prime Minister of Great Britain.
The office holder presided over the Government of the Kingdom of Great Britain until 1721 until 1801 when the Kingdom of Great Britain was unified with the Kingdom of Ireland to create the United Kingdom of Great Britain and Ireland. This office holders title formally changed to the Prime Minister of the United Kingdom of Great Britain and Ireland.
