Human Fertilisation and Embryology Bill [Lords]

On this point, as has been pointed out, Professor Chris Shaw believes that embryonic stem cells are very important in terms of MND. Does the hon. Gentleman not agree that there must be competition between parallel and different methodologies, as we do not know which ones might lead us to solutions—if we did know, we would already have cured diseases such as MND? Therefore, while there may be a favourite methodology in the end, we do not know which one it is yet. While I accept the ethical points, there needs to be such scientific diversification because we will not get things right first time.
