Human Fertilisation and Embryology Bill [Lords]

I understand the hon. Gentleman's point. The legal advice that I have received on this is contradictory; I must be honest about that. However, everyone says that the use of the word ““serious”” does not create a very tight provision, and that any effort to tighten the clause would therefore be welcome. I shall say more about that later. Amendment No. 18 would insert the word ““regenerative””. This goes back to the point made by my hon. Friend the Member for Enfield, Southgate about the words ““other tissue””. It would be helpful if the Minister could stipulate exactly what other tissue this means. I have no wish to duplicate the debate that took place in another place, in which it was made clear that this was not intended to include the removal of whole organs. I understand, however, that it could mean not only bone marrow and biopsies but partial organ removal, and that those organs—for example, a significant chunk of a liver—might not grow back. It would be helpful if the Minister could tell us whether that is being considered in this regard.
