Michael Foot was Leader of the Opposition from 4 November 1980, following his victory in the 1980 leadership election, to 2 October 1983, when he was replaced by Neil Kinnock at the 1983 leadership election. The 1980 leadership contest was triggered by James Callaghan's loss at the 1979 general election, and the 1983 contest by Foot's own disastrous defeat in the 1983 general election.
Until 2011, the Labour MPs elected the bulk of the membership of the Shadow Cabinet. The leader was expected to assign portfolios to those elected, but was able to assign portfolios to MPs not elected to the Shadow Cabinet and to refuse to assign portfolios to elected members. For example, William Rodgers was not given a portfolio despite winning in the 1980 Shadow Cabinet elections. When he left the party months later to help create the Social Democratic Party, Tony Benn automatically joined the Shadow Cabinet. Foot also chose not to give the more radical Benn a portfolio. When Benn lost in the 1981 Shadow Cabinet elections, all the new members received portfolios (Shadow Minister for Europe became a Shadow Cabinet post for the rest of Foot's tenure as leader).
Foot announced his first Shadow Cabinet on 8 December 1980, following the 1980 Shadow Cabinet elections.[1]
On 24 November 1981, following the 1981 Shadow Cabinet elections, Foot reshuffled the Shadow Cabinet. Brynmor John moved from Defence to Social Services and was replaced by Silkin, who retained the post of Shadow Leader of the House. Buchnan replaced Mason at Agriculture. Benn, Mason, and Morris were dropped from the Shadow Cabinet. Peter Archer and Eric Heffer joined the Shadow Cabinet as Shadow Attorney General and Shadow Minister for Europe, respectively.[3]
