Alcohol Harm

I apologise for intervening again, but I want to remind the hon. Gentleman of evidence that we have received. The reason that the recommendation has to be not to drink alcohol is that women’s individual alcohol tolerance levels during pregnancy are simply not known. I remember that he once mentioned a dramatic piece of evidence that showed—he will correct me if I have got it wrong—that a single drop of alcohol on an embryo resulted in that embryo becoming completely insentient for two hours. That is a startling piece of information.
