The hon. Gentleman set out the costs incurred in trying to prevent such travesties. Does he agree that the figures he refers to are actually conservative estimates? I believe that he was at the launch, quite a number of years ago, of the Maternal Mental Health Alliance, which arrived at the figure of more than £8 billion. Is it not the case that, although the economic costs are significant, it is the social and moral reasons that have brought Members from all sides of the House here for this important debate?
