From January, London buses in Westminster aim to tell commuters the truth about life, with posters saying: “There’s probably no God. Now stop worrying and enjoy your life.”

The posters have been created by the British Humanist Association (BHA) and have been supported by outspoken atheist Professor Richard Dawkins. BHA has raised more than £27,600 for the project.

Professor Dawkins said: “Religion is accustomed to getting a free ride – automatic tax breaks, unearned respect and the right not to be offended, the right to brainwash children. This campaign to put alternative slogans on London buses will make people think – and thinking is anathema to religion.”

The posters will appear on the side and inside bendy buses from January, and BHA plan to move the campaign to Birmingham, Manchester and Edinburgh.

Not surprising, not everyone is so pleased with the campaign. Stephen Green of pressure group Christian Voice said: “Bendy-buses, like atheism, are a danger to the public at large. I should be surprised if a quasi-religious advertising campaign like this did not attract graffiti.”

Hanne Stinson, chief executive of the BHA, is more light hearted about the campaign: “We see so many posters advertising salvation through Jesus or threatening us with eternal damnation, that I feel sure that a bus advert like this will be welcomed as a breath of fresh air. If it raises a smile as well as making people think, so much the better.”

And what better way to cheer up a miserable commute on a Monday morning.
