The UK shadow cabinet is the front bench of the official parliamentary opposition party. It seeks to present itself as an alternative government for the next general election. It grew out of the practice that developed in the late nineteenth century of the ex-cabinet continuing to meet after election defeat in order to lead the opposition against the new cabinet. Since the 1950s it has become a key dimension of the formalized process of parliamentary adversarial politics. A Labour shadow cabinet would be based on members elected by the parliamentary Labour Party, whilst a Conservative shadow cabinet is appointed by the party leader.
