^ For the 1918 election, MPs are given out of the Ireland total. For subsequent elections, MP totals are for Northern Ireland.

^ Four Sinn Féin candidates were elected in two constituencies each, so Sinn Féin actually had 69 out of 101 Irish MPs. In what was to become Northern Ireland, Sinn Féin won 3 seats out of a possible 30.
