The shortlist for the UK’s best-known art award, the annual Turner Prize, has been announced this morning. The nominees competing for the £25,000 prize, now in its 30th anniversary year, are Duncan Campbell, James Richards, Ciara Phillips and Tris Vonna-Michell.

Dublin-born Duncan Campbell is nominated for his film ‘It for Others’, an examination of cultural imperialism shown at last year's Venice Biennale, and English artist Tris Vonna-Michell is shortlisted for an installation based on his mother's childhood in Berlin. The other two shortlisted artists are Canadian Ciara Phillips who has been chosen for a collaborative print studio project, and James Richards, the youngest artist, who is nominated for a black and white film (also show at the Venice Biennale).

Complying with the criteria of the prize, all of the nominees have shown an outstanding exhibition or presentation of their work in the previous 12 months, and are under 50, living, working or born in Britain. A winner will be chosen from this four-strong shortlist and announced on the 1st of December at a ceremony at Tate Britain in London.
