A controversial atheist advertising campaign has moved from London buses to billboards in four British cities.

Donations have funded billboards in London, Edinburgh, Cardiff and Belfast with a new slogan: "Please don't label me, let me grow up and choose for myself."

Comedy writer Ariane Sherine, who started the campaign, said supporters were concerned about the growth of faith schools in the U.K.

"Many felt strongly that children should be given the freedom to decide which belief system they wanted to belong to, if any, and that they should not have a religion decided for them," Sherine told the Guardian.

"We thought it would be beneficial to try to change the current public perception that it is acceptable to label children with a religion."

Sherine's campaign began when she wrote an article suggesting if atheists reading it donated $9 each, they could fund an advertisement on London buses.

The advert said: "There's probably no God. Now stop worrying and enjoy your life."

There was enough money left over after the campaign launched in October 2008 to fund the billboards.
