Ian Katz says new show, Art Trouble, celebrates the channel’s tradition of ‘iconoclasm and irreverence’

Channel 4 has bought a painting by Adolf Hitler and will allow a studio audience to decide whether Jimmy Carr should burn it with a flamethrower.

As part of its latest season of programmes, the TV channel has bought artworks by a range of “problematic” artists, including Pablo Picasso, as well as convicted paedophile Rolf Harris and sexual abuser Eric Gill.
