Newsjack was a British satirical sketch show which was broadcast on BBC Radio 4 Extra between 2009 and 2021. It was hosted by Miles Jupp, Justin Edwards, Romesh Ranganathan (2014), Nish Kumar (2015–2016), Angela Barnes (2017–2018) and Kiri Pritchard-McLean (2019–2021). It was first broadcast on 4 June 2009. The series was notable for having an "Open door" policy on writing, advertising itself as "the scrapbook sketch show written entirely by the Great British public" meaning that unsolicited writers without contract to the BBC could send in material. The show was designed to give new writers an opportunity to get material broadcast. It was hoped by the people behind the show that it would be a modern version of Week Ending, an earlier sketch show which also accepted material the same way. Most shows were recorded in front of a live audience at the BBC Radio Theatre in Broadcasting House.

BBC Radio 4 Extra is a British digital radio station from the BBC, broadcasting archived repeats of comedy, drama and documentary programmes nationally, 24 hours a day. It is the sister station of BBC Radio 4 and the principal broadcaster of the BBC's spoken-word archive, and as a result the majority of its programming originates from that archive. It also broadcasts extended and companion programmes to those broadcast on Radio 4, and provides a "catch-up" service for certain programmes.
