Medical Malpractice Insurance: I think it's this one but if I am not mistaken, you are only covered from the period of time that you were a member, so therefore if anyone were to try to take you to court for a case, and you happened to have not been a member during the time the event took place, then you will not be covered.
Also, if you are employed by a Trust, you are covered by the Trust's vicarious liability.
Additionally, if you intend you practise independently, you will not be covered by this insurance.
I'm happy to be corrected.
