Alexei David Sayle is an English actor, author, stand-up comedian, television presenter and former recording artist. He was a leading figure in the British alternative comedy movement in the 1980s. He was voted the 18th greatest stand-up comic of all time on Channel 4's 100 Greatest Stand-ups in 2007. In an updated 2010 poll he came 72nd.

Much of Sayle's humour is in the tradition of Spike Milligan and Monty Python, with riffs based on often absurd and surreal premises. His act is known for its cynicism and political awareness, as well as physical comedy.
