Gash is a satirical British television comedy created by Armando Iannucci that was broadcast each weeknight from Monday 28 April to Thursday 1 May 2003 on Channel 4 to coincide with the 2003 local elections.^[1] Written and filmed on the day of transmission, the programme was a topical review show featuring sketches, modified VT footage, talk, discussion and jokes. The name derives from a television term for footage surplus to requirements.^[1] The show featured appearances from Olivia Colman, Dominic Holland, Jon Holmes and John Oliver, amongst others.^[2][3]

Many of the writers of the show – Simon Blackwell, Roger Drew, Tony Roche and Will Smith – went on to collaborate with Iannucci on the political sitcom The Thick of It (2005–2012) and Time Trumpet (2006). Other writers included Dan Tetsell, Danny Robins and Jon Holmes.^[2] Perhaps due to its topical nature, the series is not available on any commercial media formats or even via 4oD. It was produced by David Tyler and was a Talkback (production company) production in association with Pozzitive Television.
