Human Fertilisation and Embryology Bill [Lords]

I am still a little confused, because there are two issues here. First, is the tetraploid complement embryo actually human at the point at which the hon. Gentleman envisages it would be implanted, bearing in mind that the embryo itself does not include the animal-derived trophectoderm that forms the placenta, in which case the Minister is right and it would be covered? I see the Minister nodding. In any event, does the hon. Gentleman accept that in order for appropriate implantation, there would have to be a close species match? Would that not require a licence from the Animal Procedures Committee that it would be extremely unlikely to give? Is not the hon. Gentleman's amendment therefore unnecessary in both those cases?
