The final line-up for the London 2012 festival was announced on Thursday, with around 12,000 events happening across Britain in a major cultural celebration organised to coincide with the summer Olympic Games.

Music, dance, theatre, cinema, art and architecture are on the agenda during the June 21-September 9 event, which spans the Olympic and Paralympic Games.

The 12-week arts festival is the climax of the four-year Cultural Olympiad, designed to showcase Britain's prominent place in the arts in the buildup to the Games.
