I warmly welcome the Cass review and its findings, and the extraordinarily strong statement made by my right hon. Friend. I have no doubt that what happened at GIDS—the Gender Identity Development Service—will go down as one of the worst safeguarding and medical scandals of our generation. I pay tribute to the brave parents, including those in the Bayswater support group, who have been raising concerns for years about the ethics and the safety of putting vulnerable children on irreversible and unevidenced medical pathways with the aim of achieving something that can never be achieved, which is to change their sex. Those who spoke up for the interests of children and, frankly, for the interests of common sense were labelled bigots, transphobes and even fascists. Even after concerns were raised and Dr Cass had been commissioned, the Tavistock was allowed to continue to practise, which was a shocking suspension of the precautionary principle. This scandal happened because too many adults put their own desire for social approval above the safety of vulnerable children. How can we make sure that that does not happen again?
