I’m no fan of Dr Webberley - but she hasn’t had her license “removed”, she opted not to undergo revalidation so gave the license up.
She is still registered with the GMC, and she is currently in good standing with the GMC.
She can still describe herself as a doctor as she is a doctor.
What she can’t do is practise medicine, as she doesn’t currently have a license. She is also bound to follow the GMC’s rules for registrants (basically not brining the profession into disrepute).
If anyone has evidence she is practicing medicine they should report via the GMC website. Similarly, concerns re bringing the profession into disrepute can also be reported via the website.
(I would hope that the GMC would not sanction a registrant for expressing GC views. I thus expect the same protection for doctors expressing views I disagree with. I haven’t seen her recent posts so I don’t know whether they go beyond expressing views I disagree with.)
