John Granville Colpoys Keane (born 12 September 1954) is a British artist, whose paintings have contemporary political and social themes.
[4] He also worked on paintings about the 2002 Moscow Theatre siege, using documentary footage as a source: "The process has continued my methods of developing the imagery with the aid of a computer, prior to committing paint to canvas in works both large and small scale.
"[4] In 2006, 57 Hours in the House of Culture was a show at Flowers East gallery, London, and Sakharov Museum, Moscow, about the Chechen War.
[4] His more recent work, Guantanamerica, bases paintings about "issues of representation and dehumanisation of detainees at Guantánamo Bay" on low resolution internet files.
[10][11][12][13] In November 2019, along with other public figures, Keane signed a letter supporting Labour Party leader Jeremy Corbyn describing him as "a beacon of hope in the struggle against emergent far-right nationalism, xenophobia and racism in much of the democratic world" and endorsed him in the 2019 UK general election.
