Despite initial optimism and the professional campaign run by Neil Kinnock, the election brought only twenty additional seats for Labour from the 1983 Conservative landslide. In many southern areas, the Labour vote actually fell, with the party losing seats in London. However, it represented a decisive victory against the SDP–Liberal Alliance and marked out the Labour Party as the main opposition to the Conservative Party. This was in stark contrast to 1983, when the Alliance almost matched Labour in terms of votes—although Labour had almost 10 times as many seats as the Alliance.
