It’s almost as if this controversy isn’t medical at all but purely political.

‘Witch-hunt’: BMA tries to identify who leaked planned opposition to Cass review

The British Medical Association (BMA) has been accused of undertaking a “witch-hunt” to try to identify which senior figure leaked that it was set to oppose the landmark Cass review on transgender healthcare.

It has warned its ruling council’s 69 members that whoever tipped off the media about its stance should own up or face their non-cooperation being seen as “an act of dishonesty”. Critics said its action is “disgraceful”, “Orwellian” and “witch-hunt-like”.

In other words not medical, not technical, not about evidence or argument, but a matter of loyalty and commitment. Politics rather than epistemology.

The BMA has been heavily criticised by key medical figures since it voted on 17 July to in effect reject Dr Hilary Cass’s report. It is the only medical organisation in the UK to not accept and find fault with her findings, which were accepted by the last government and its Labour successor.

It’s the Guardian saying all this. Something has shifted. No doubt the Cass report itself helped that shift.

The union has been in turmoil ever since. Its dismissal of the report as “unsubstantiated” has led to a serious split, resignations and huge tension within the body that represents about 195,000 doctors – a large majority of the UK medical profession.

As it should. The dismissal is outrageous – political instead of medical.

Dr Clare Gerada, an ex-BMA council member and ex-chair of the Royal College of GPs, said: “I think the BMA are blaming the messenger, not themselves.” She questioned why it had adopted such a controversial position on such a sensitive subject without asking members for their views first. She is among an array of leading doctors who have signed a letter voicing serious concern at the BMA’s stance.

The edifice is tilting.
