First artist to win the award twice

PJ Harvey has won the Barclaycard Mercury Music Prize 2011, becoming the first artist to win the award twice.

PJ Harvey previously won in 2001 for her album Stories from the City, Stories from the Sea. Now, a decade on, her latest album Let England Shake won the accolade.

Broadcast live on BBC2, the event included live performances from all the nominees - Ghostpoet, Elbow, Tinie Tempah, James Blake, Anna Calvi, Everything Everything, Gwilym Simcock, Metronomy, Katy B and King Creosote & John Hopkins. Adele was also a nominee but could not sign because of a chest infection.

The Mercury prize is the most coveted award in the UK music industry, chosen by critics and experts on the merit of the music alone, and has a £20,000 prize. Last year's winner was indie band the xx with their debut album The xx.
