Bono’s star-studded famine commercial has been banned from airing on U.K. TV – because broadcasting officials fear the clip breaches rules regarding political advertising.

The U2 rocker shot the minute-long advert with a slew of his celebrity pals, including George Clooney, Jessica Alba and Colin Farrell, to raise awareness about the famine crisis sweeping across Eastern Africa.

The F Word: Famine is the Real Obscenity, which was produced by Bono’s One charity, is aimed at urging government officials to do more to tackle the hunger issue, but the TV commercial has now been taken off the airwaves by bosses at governing body Clearcast amid worries its message could potentially conflict with the terms stated in the 2003 Communications Act.

A Clearcast spokesperson tells BBC News, “These rules ensure that adverts aren’t being broadcast by bodies whose objects are wholly or mainly political.”

“One (charity) appears to be caught by this rule as they state that part of their raison d’etre (reason for existence) is to pressure political leaders. It also appears that a number of the claims made in the version of the ad that we have seen are directed towards a political end, which is again against the rules.”
