on the Thames in Greenwich; RAF Typhoon jets will be stationed at Northolt; and specialist bomb disposal teams will be deployed next summer - all as part of the Olympic security operation the Ministry of Defence announced today.

The extra costs will come out of the Olympics budget, not that of the Ministry of Defence.
