From as early as the 1970s John Walker was one of the most influential  and imitated painters working in the UK; he exhibited alongside Andy  Warhol and Roy Lichtenstein, represented his country at the 1972 Venice  Biennale, had extensive survey shows at both the Tate and Hayward  galleries and was nominated for the Turner Prize in 1985.

On the occasion of Walker's exhibition at Messums London, we present a conversation between John and Jonathan Watkins. Jonathan Watkins is an English curator, and the former Director of the Ikon Gallery in Birmingham.
