Great Britain was divided into single-member First Past the Post constituencies from the 1979 election until the 1999 election, when it was divided into the current twelve multimember D'Hondt party list constituencies. Northern Ireland has been a single constituency using Single Transferable Vote since 1979.

With the exception of Gibraltar's inclusion in South West England, the constituencies otherwise correspond with the NUTS 1 regions of the United Kingdom, though the naming differs slightly to distinguish them from other European constituencies.
