He is the rock legend dubbed 'Saint Bono' for his long-running campaign against global poverty.

But when Bono's band U2 perform at Glastonbury later this month, protesters are planning to accuse them of avoiding taxes which could have helped exactly the sort of people the singer cares about so dearly.

Members of activist group Art Uncut will hoist a massive inflatable sign with the message 'Bono Pay Up' spelt out in lights during the Irish band's headline performance.

They will also parade bundles of oversized fake cash in front of the singer.

The protest has been provoked by U2's decision to move their multi-million-pound music and publishing business away from Ireland – thus allegedly avoiding taxes on record sales.
