Probably not any more!
Since Shipman, it appears the GMC has been much changed and is now perceived by many in the medical profession as a confrontational and sometimes vindictive organisation with a "guilty until proven innocent" ethos. It is alleged that it has since been the cause of suicide, emigration and many an early retirement with most of the victims never being shown to be guilty.
The GMC certainly does not "look after its own" if you mean it is looking after doctors, that is.
