The United Kingdom, a constitutional monarchy located slightly off the coast of continental Europe, has been an OSCE participating State since June 25, 1973. A member of NATO, the E.U. and the Council of Europe, the United Kingdom has an ethnically and religiously diverse population of about 62 million.  Financial and insurances services drive its economy.

Recent Commission work has focused on the topic of collusion in Northern Ireland during the Troubles. The UK has also periodically had its elections observed by the OSCE/ODIHR, and Commissioners have visited the UK on numerous occasions, including for OSCE and OSCE PA meetings.  The UK has had an increased OSCE and Commission focus in recent years as a result of issues related to security, the economic downturn, and migration.
