The Conservatives won double the number of seats they had won in the previous European election, in 1994, while the Labour Party saw its seats reduced from 62 to 29. The Liberal Democrats saw their number of seats increase to 10 from just 2 in the previous election. The UK Independence Party (UKIP), Green Party and Plaid Cymru gained their first seats in the European Parliament.
