"General Medical Council. It's basically the people in charge of all the doctors in Britain. We have to register with them to make it legal to practice medicine. If you get struck off, it means you can't be a doctor any more. It's most doctors' worst nightmare.
They keep an eye on doctors to make sure we're doing our jobs properly. To make sure we aren't abusing patients and so on. There have been a few pretty nasty cases of doctors committing murder and such in the past, by abusing their positions of trust. Systems like the GMC are there to try to prevent that sort of thing happening again."
