The Rank and File Mobilising Committee (RFMC) was an umbrella group which coordinated left wing groups to campaign for increased democracy within the Labour Party. The RFMC operated from 1980 to 1981, during which time it defended the mandatory reselection of MPs (won at the 1979 Party Conference), secured an electoral college for the election of Labour Leaders and provided the organising base for Tony Benn's 1981 Deputy Leadership campaign, which narrowly lost with 49.6% of the vote.
