 The Labour Party's most emphatic gains were in Scotland, where, from a single seat at the last election, they picked up another 36. Most of them were at the expense of the pro-independence Scottish National Party, which lost 80% of its support. Labour also gained seats in Wales, where the Conservatives were completely wiped out. In Northern Ireland, the Irish Republican Party, Sinn Fein, won the most seats at Westminster for the first time.
