The Department for Education has revised its model funding agreement, allowing the education secretary to withdraw cash from schools that fail to meet strict criteria relating to what they teach. Under the new agreement, funding will be withdrawn for any free school that teaches what it claims are “evidence-based views or theories” that run “contrary to established scientific and/or historical evidence and explanations”.

The British Humanist Association (BHA), which has led a campaign against creationism – the movement that denies Darwinian evolution and claims that the Earth and all its life was created by God – described the move as “highly significant” and predicted that it would have implications for other faith groups looking to run schools.

Dawkins, who was one of the leading lights in the campaign, welcomed confirmation that creationists would not receive funding to run free schools if they sought to portray their views as science. “I welcome all moves to ensure that creationism is not taught as fact in schools,” he said. “Government rules on this are extremely welcome, but they need to be properly enforced.”
