I don't think there is any current threat to suspend or strike off Dr Myhill. I believe that reference is to GMC proceedings which took place against her around 2010-12. I think she was suspended at one point, then reinstated. It was all very complicated, and initiated in no small way by certain "skeptical" bloggers who took it upon themselves to attack her, dissecting her website for anything which might constitute an unsubstantiated claim. The GMC didn't cover themselves in glory, either, causing a lot of uncertainty and grief before finally fudging the whole business. -

I think the Guardian piece above was an invitation to nominate her as part of International Women's Day.
