Creationism and Intelligent Design pose a far greater threat to education in the US than they do in most parts of the UK. For fuller discussion see the [US] National Center for Science Education website.
The current Creationist/Intelligent Design movement in the UK draws much of its materials and inspiration from the Seattle-based Discovery Institute, whose stated goal is to replace naturalistic with theistic understanding.
For this reason, much Creationist material in the UK is best understood by reference to the very different legal and constitutional situation in the US. We cannot attempt to cover this vast topic, but would draw attention to an Open Access article by Nick Matzke in Evolution Education and Outreach, for a full analysis.
