Human Fertilisation and Embryology Bill [Lords]

May I offer my support for my hon. Friend's amendment No. 49, which is at the head of the group that we are discussing? I have no doubt that the regulations in the clause would stop nuclear modification to prevent cytoplasmic disease, and the Human Fertilisation and Embryology Authority would not, in any event, license such a procedure, but my hon. Friend is right: it is sensible for legislation to say what it means. There is no doubt that the Government mean the provision to deal only with cytoplasmic causes of mitochondrial disease in DNA. It is unfortunate that the Bill reaches us in this imperfect form, but my hon. Friend's amendment would improve it.
