Human Fertilisation and Embryology Bill [HL]

My Lords, I support the noble Lord, Lord Walton. The idea that stem cells should eventually be used for treating diseases is a major selling point of this Bill for the general public. We must have some clarification on that. In Committee, I understood that primary legislation was needed to achieve that purpose. In the letter from the Department of Health I think we are now being told something different, but I confess to not really understanding the letter. Therefore, I hope the Minister will now clarify the position for the benefit of all of us.
