U2 frontman Bono credits himself with inspiring other celebrities to join him in the campaign to make poverty history.

In recent years the WITH OR WITHOUT YOU hitmaker has been joined on the podium by A-listers such as ANGELINA JOLIE - and he insists it can only be a positive thing for his current cause, the One Campaign, which bids to sign up Americans to fight Aids and poverty in Africa.

He says, "We've got others coming through now: Angelina Jolie, George Clooney, Brad Pitt.

"It's the movement that will stop the tin-cupping and give us real political muscle.

"By 2007, the year of the next American election, I am assured that there will be five million Americans (One Campaign members), which makes us bigger than the National Rifle Association."
