U2 have announced full details of their world tour, which will begin at the Nou Camp stadium in Barcelona on June 30th.

The 360° tour will visit 14 cities across Europe in support of the Irish band's number one album 'No Line On The Horizon'.

The jaunt features four dates in the UK, including a show at London's Wembley Stadium on August 14th.

The stage set will feature an innovative 360° design which affords an unobstructed view for the audience.
