A coalition of Greek mythological creatures has written to every MP urging them to back the Human Fertilisation and Embryology Bill, which will allow the creation of part-human, part-animal embryos. At the weekend Scottish Cardinal Keith O'Brien said the bill would allow "grotesque procedures" which would "attack the sanctity and dignity of human life," but the Minotaur today criticised the church's stance on the issue. "Some people say that these Cardinals are potential human beings and should be treated with respect, but we cannot agree with that," said the half man, half bull. "Without this sort of scientific breakthrough we would have had no Sphinx, no Siren, no Centaur," he added. "And would the cruel church really wish to deny the Satyr his boundless, immortal erection?"
