United Kingdom country profile
The United Kingdom is made up of England, Wales, Scotland and Northern Ireland. It has a long history as a major player in international affairs and fulfils an important role in the EU, UN and Nato.
The twentieth century saw Britain having to redefine its place in the world. At the beginning of the century, it commanded a world-wide empire as the foremost global power.
Two world wars and the end of empire diminished its role, but the UK remains an economic and military power, with considerable political and cultural influence around the world.
In 2016 the country voted in a referendum to quit the European Union.

Head of state: Queen Elizabeth II
Elizabeth II became queen of the United Kingdom of Great Britain and Northern Ireland in 1952 upon the death of her father, George VI.
In September 2015, she became Britain's longest-reigning monarch, surpassing the record of her great-great grandmother, Queen Victoria.
She is also head of state of 16 independent countries including Canada and Australia.
As a constitutional monarch, her role in the legislative process is largely ceremonial.
Prime minister: Theresa May
Theresa May became prime minister in July 2016 on the resignation of her predecessor and fellow Conservative, David Cameron, in the wake of a referendum vote for Britain to leave the European Union.
Mrs May backed Mr Cameron's support for Britain to remain in the EU, but faces the task of overseeing its exit before the next general election in 2020. She served as home secretary in both of Mr Cameron's governments, the 2010-2015 Conservative/Liberal Democrat coalition and the 2015-2016 Conservative majority administration, acquiring a reputation for combining firmness on security with a relatively liberal stance on social issues.
The UK has a strong tradition of public service broadcasting and an international reputation for creative programme-making.
The fledgling BBC began daily radio broadcasts in 1922 and quickly came to play a pivotal role in national life. The Empire Service - the forerunner of the BBC World Service - established a reputation worldwide. The BBC is funded by a licence fee, which all households with a TV set must pay.
Commercial TV began in 1955 with the launch of ITV, while commercial radio arrived in the 1970s. Hundreds of privately-owned radio and TV stations now compete with the BBC for listeners and viewers.
There are numerous national and local papers, reflecting the full spectrum of news and opinion. In recent years, printed newspaper circulations have been sliding while online readership has surged.
