Foreign, Commonwealth and Development Office

The Foreign, Commonwealth & Development Office is a department of the Government of the United Kingdom. Equivalent to other countries' ministries of foreign affairs, it was created on 2 September 2020 through the merger of the Foreign & Commonwealth Office and the Department for International Development. The FCO, itself created in 1968 by the merger of the Foreign Office and the Commonwealth Office, was responsible for protecting and promoting British interests worldwide.

The head of the FCDO is the Secretary of State for Foreign, Commonwealth and Development Affairs, commonly abbreviated to "Foreign Secretary". This is regarded as one of the four most prestigious positions in the Cabinet – the Great Offices of State – alongside those of Prime Minister, Chancellor of the Exchequer and Home Secretary. James Cleverly was appointed Foreign Secretary on 6 September 2022.
