That experience clearly contradicts the Cass review’s findings, but it is for the hon. Lady to have that debate, no doubt, with Dr Cass. What is certain is that we have no indication from the Government about what success in the trial will look like. When challenged on that subject, answer came there none. How will we gauge whether the trial is a success or a failure? Are these children really guinea pigs to be used to provide the evidence that the hon. Lady says is already freely available in her anecdotal experience of communicating with her constituents and others? We know that there is certainly evidence from other countries. Have the Government looked to draw on that, rather than engaging in this dangerous trial? We know that there is evidence too from the 2,000 or more children who went through Tavistock. Some have suggested that we should look at the data already available rather than putting any more children at risk. Yet despite the Secretary of State’s agonised decision—I do not intend that to be sarcastic or pejorative; I appreciate that the Secretary of State was completely straightforward about how difficult it was to make the decision—the trial goes ahead. I accept that there are additional safeguards—this is not Tavistock; it is something different—but none the less it brings immense risk alongside the determination to try to gain facts. Instead, let us look at Finland and Denmark and at other countries that have already gathered evidence. Let us look at what we know of those who have already been through this process. G. K. Chesterton said: “children are innocent and love justice”. I fear that this trial will steal their innocence and deny them justice. I hope that even at this late stage the Government, recognising that, will abandon this awful trial and save innocent children from that fate.
