He won the Turner Prize in 1999, although much of the publicity went to Tracey Emin, who was also a nominee. In 2006, he went to Iraq as an official war artist. The following year he presented "Queen and Country", a piece that commemorated the deaths of British soldiers who died in the Iraq War by presenting their portraits as sheets of stamps. A proposal to have the stamps placed in circulation was rejected by the Royal Mail. His 2007 short film "Gravesend" depicted the process of coltan refinement and production. It premiered at The Renaissance Society in the United States.
