Steve McQueen's Year 3 children exhibition unveiled at Tate

Oscar-winning filmmaker Steve McQueen has photographed more than 75,000 Year 3 children across London's schools for his latest exhibition.

The project aims to be a visual snapshot of people in the city and was inspired after the Turner Prize-winning artist looked at his own 1977 class photo.

The photos are also being showcased on billboards by roads, railways and train stations across the capital.
