The
constitution of the United Kingdom is the sum of
laws and principles that make up the
body politic of the
United Kingdom. It concerns both the relationship between the individual and the state, and the functioning of the legislature, the executive and judiciary. Unlike many other nations, the UK has no single constitutional document. This is sometimes expressed by stating that it has an
uncodified or "unwritten" constitution. Much of the British constitution is embodied in written documents, within
statutes,
court judgments,
works of authority and
treaties. The constitution has other unwritten sources, including
parliamentary constitutional conventions.
