The British–Irish Council is an intergovernmental organisation that aims to improve collaboration between its members in a number of areas including transport, the environment and energy. Its membership comprises Ireland, the United Kingdom, the devolved governments of Northern Ireland, Scotland and Wales, in addition to the governments of the British Crown Dependencies: Guernsey, Jersey and the Isle of Man. As England does not have a devolved administration, it is not individually represented on the council but only as a member of the United Kingdom.

In the United Kingdom, devolution is the Parliament of the United Kingdom's statutory granting of a greater level of self-government to the Scottish Parliament, the Senedd, the Northern Ireland Assembly and the London Assembly and to their associated executive bodies: the Scottish Government, the Welsh Government, the Northern Ireland Executive and in England, the Greater London Authority and combined authorities.
