As there was quite a lot of talk about "inquiries" here, either public or parliamentary, and a lot of you are discussing this from a GB only perception, let me give you an international perspective.
In many countries, as in my country Switzerland, there are no such thing as "public inquiries" and the parliamentary inquiries are extremely rare, they happen like once a decade and always had to do with money missmanagement inside the government.
Furthermore, in countries such as France, Belgium, and the Scandinavian countries, as of now there seems to be a complete lack of even basic awareness that there could be a problem.
This idea of “how can we finally bring justice” may sound tempting but it's useless and in many countries simply not possible, not even in theory.
The only thing that has worked politically is lobbying members of parliament and, in the best-case scenario, members of the government. That’s how the Germans managed to secure 50 million in research funding for post-infectious diseases, and that’s how we in Switzerland managed to at least force our Ministry of Health to address these conditions, although I have no real hope that they'll do something useful. The focus in both cases wasn't on abuse and malpractice, as most people see Drs. as saints anyway, but the focus was on suffering and not-fulfilled needs of people with ME.
With Drs. however it's basically impossible to reach them through politics or inquiries—politicians are too cowardly for that, and doctors are too stubborn. As has already been correctly described here several times, the only way to reach doctors is through research findings or, by chance, through personal contacts.
