Westminster Hall is an alternative Chamber for MPs to hold debates, named after the adjoining Westminster Hall.

Each debate is chaired by an MP from the Panel of Chairs, rather than the Speaker or Deputy Speaker. A Government Minister will give the final speech, and no votes may be called on the debate topic.

It is a pleasure to serve under your chairmanship, Mr Mundell. I want to start with the expression, “Do no harm.” To be clear for the people who have come to speak to me—parents and young people themselves—we are doing them harm by not giving them the treatment they need, with the wait times of six years, and potentially in respect of puberty blockers, where that is agreed with their healthcare professionals.

My overarching concern is that the clinical trial was suggested in the Cass review. It was proposed and designed in conjunction with the MHRA, but then the MHRA changed its mind. Why was that? Dr Hilary Cass said:

“There are no new research findings and the MHRA hasn’t presented any new evidence. It feels to me like they are responding to political pressure rather than to science.”

That is what she said; I was quoting her verbatim. It was her review that the people around this Chamber wanted us to listen to and to make changes in response to, so we have to listen to her in this instance as well.

The MHRA should operate without any political interference or fear of legal action, yet the MHRA itself referenced potential legal action in relation to the trial as one of the reasons why it changed its mind. That is a problem. The MHRA is there to make sure that anything from clinical trials to medical technologies and new drugs are dealt with on the basis of science and science alone.

The problem is that the MHRA lead, Professor George, is being hounded and scapegoated after recusing himself. It is really sad to see a professional in such a situation. I urge my hon. Friend to use words with caution, because he recused himself. He is a great man who is being hounded.

I am not for hounding any particular individual. The only person I have referred to by name is Hilary Cass and she has been on the public record. I have been hounded for my views as well—

Exactly, and that is completely inappropriate. A leader of a political party shouted “Traitor” at me when I said we should watch our language around this issue. I do not know who they think I am a traitor to, but I am certainly not one to the human race. The hon. Member for Canterbury (Rosie Duffield) has said she has received death threats; I get death threats too. This is not unique to the hon. Member.

The MHRA should not be in an environment where it has any fear of any legal action; it should only look at the science. Many in the community feel that the trial has now become too political for anybody to touch and that we have forgotten about those children who, quite frankly, if we do not do anything for them, we are doing harm.
