Neil Kinnock was Leader of the Labour Party and Leader of the Opposition from 2 October 1983 to 18 July 1992. He convincingly defeated Roy Hattersley, Eric Heffer, and Peter Shore in the 1983 leadership election, which was prompted by Michael Foot's resignation following the disastrous general election result earlier that year. Kinnock's period as Leader encompassed the bulk of the Thatcher premiership and the first two years of the Major premiership. Kinnock resigned in 1992 after losing his second election as Leader.
