Protesters are threatening to take over later this evening (June 24) when rockers U2 take the stage at 2011's Glastonbury Festival. 

Art Uncut, a direct action group, have promised to unleash a giant inflatable in front of the BBC's camera crew before the 'Elevation' stars headline the Pyramid Stage tonight to campaign against the band's alleged 'tax dodge' in their native Ireland. 

Campaign activist, Anna Walker, said:

"Everyone there will see it. If the BBC do not broadcast it, there is little doubt that it will have been an editorial decision."

Another campaigner, Charlie Dewar, added:

"U2's multimillion-euro tax dodge is depriving the Irish people at a time when they desperately need income to offset the Irish government's savage austerity programme."

"Tax nestling in the band's bank account should be helping to keep open the hospitals, schools and libraries that are closing all over Ireland."

"Bono is well known for his anti-poverty campaigning but Art Uncut is accusing him of hypocrisy."
