the proscution insulin expert has relenquished his licence for some reason
i think that reason is the ongoing GMC investiation against him and the "conditions placed on his licence to practice". He must be supervised at all times. See link below and click onto link for "Registrant history" and then the link about "Interim conditions"
https://www.gmc-uk.org/registrants/2459998 From the interim conditions;
"5. a. He must be directly supervised in all of his posts by a clinical supervisor, as defined in the Glossary for undertakings and conditions. His clinical supervisor must be appointed by his responsible officer (or their nominated deputy). b. He must not work until: i. his responsible officer (or their nominated deputy) has appointed his clinical supervisor and approved his supervision arrangements ii. he has personally ensured that the GMC has been notified of these arrangements. c. He must provide a report from his clinical supervisor in advance of or at his next IOT review hearing."
" 4. He must notify any instructing organisation when acting or accepting instructions as an expert witness as to this and any ongoing GMC investigation."
