Human Fertilisation and Embryology Bill [Lords]

I am listening very carefully to what the hon. Gentleman is saying. His basic argument relates to something falling outside the current prohibitions in the Bill. However, does he not agree that the definition of human admixed embryos, already discussed in the House, covers tetraploid complementation so that the Bill's prohibitions would apply? The embryos could not therefore be placed into an animal, which is the fear that the he is expressing. The Bill therefore deals with the problem.
