A committee chaired by Prime Minister David Cameron this (Tuesday) morning decided to issue more than one thousand additional armed personnel amid continued concern about Olympic security staffing levels. London Organising Committee (Locog) chief executive Paul Deighton said: "The reason that this decision has been taken is just to absolutely de-risk any aspect of the operation… with three days to go." The extra troops, who had been on 48 hours' notice, were called up before the weekend.
