The United Kingdom (UK) is a political union of four countries—England, Scotland, Wales, and Northern Ireland—located off the northwestern coast of mainland Europe. Its capital is London, a global center for finance, law, media, and international diplomacy.
The UK operates under a constitutional monarchy with a parliamentary democracy, meaning the monarch is the head of state while elected officials govern. The UK has a major global footprint in economics, defense, technology, culture, and international law, and it maintains independent policies following its exit from the European Union (Brexit).
