This week, Catholics and Humanists met in London to discuss such contentious issues as Aids, same-sex adoption and faith schools.

The meeting followed a "rowdy" public debate before the papal visit where Catholic speakers were heckled and found it difficult to get their points across. This prompted both sides to seek another opportunity to discuss the matters raised in a calmer, more rational manner.

Some believe this presents a thrilling chance to "re-boot" relations between Catholics and committed atheists. They argue that a less strained relationship will benefit both groups and that talks could even lead to co-operation in tackling pressing social issues such as poverty.
