The Foreign, Commonwealth and Development Office (FCDO) is a department of the United Kingdom government responsible for foreign affairs, international development, and promoting British interests abroad. It was formed in September 2020 by merging the former Foreign and Commonwealth Office and the Department for International Development. The FCDO works to enhance global security, support economic growth, and address global challenges such as climate change and poverty. The FCDO engages with various international organizations, including the United Nations and the European Union, to foster diplomatic relations and cooperation. It also provides support to British citizens overseas and works on issues like human rights and conflict resolution. Through its efforts, the FCDO aims to create a safer and more prosperous world.
