Bono has confessed that he often gets tired of his own preaching.

The U2 star has recognised that some fans are becoming tired of his lectures, but insists that he is "representing the poorest and most vulnerable people" against politicians.

"I'm sick of Bono. It's like, 'Oh man, shut up.' But there it is," the singer told the Daily Star.

"I have no fear of politicians. I'm throwing a punch and the fist belongs to people who can't be in the room, whose rage, whose anger and whose hurt I represent."
