The Government of the United Kingdom, known as His Majesty’s Government, acts as the central executive authority of the United Kingdom of Great Britain and Northern Ireland, operating under an uncodified constitution. Headed by the Prime Minister—currently Sir Keir Starmer—it functions within a framework where the monarch’s symbolic role is supported by the Cabinet’s executive authority.
Historically, authors like Bernard Holland stressed the Sovereign’s ultimate power over the Empire, while the Cabinet Manual highlights the government’s dual function as both the monarch’s administration and a body responsible to Parliament. John Stuart Mill’s reflections on representative governance emphasize the tension between tradition and democratic participation, illustrating how the UK’s system balances constitutional continuity with changing political duties. This combination of royal authority, parliamentary supremacy, and devolved administration defines its distinctive structure.
