The “NHS’s conclusions” are not the conclusions of the whole body of doctors and nurses and specialists that make it up. If international health bodies have disagreed with the Cass Review, and specialists within the NHS have also disagreed with it, that doesn’t really paint a unified position of “the NHS” does it? This decision is painfully political and clearly up for debate, and the people in charge have made a political decision to take such an aggressively cautious position as to effectively fall entirely on one side of the argument.
