A bus poster which read: “There definitely is a God” attracted more complaints than any other advert in 2009, the Advertising Standards Authority has said.
A total of 1,204 people complained that the Christian Party ad was offensive to atheists and could not be substantiated.
The ASA did not investigate the ad — a response to a British Humanist Association (BHA) poster reading: “There is probably no God. Now stop worrying and enjoy your life” — because political party campaigns are outside its remit.
BHA chief executive Andrew Copson said: “Our adverts were a light-hearted response to exactly the kind of dogma that says people must be told what to believe and how to live, often accompanied by the threat of punishment in another world.”
