When I was an army doctor working full time for the British army, I was involved in the policy side of infectious disease prevention, which included malaria. Since leaving the army I haven't been involved in veterans' organizations at all. I'm not involved in any lobbying groups. That was deliberate; I didn't want to give the impression that I was taking on a particular side. I've remained independent. I hope that answers the question.
