It staggers me that anyone can compare the costs of Trident with that of the Red Arrows/BBMF!!
Current annual costs for Trident = over £2billion pounds for 2007/08
Current annual costs for Red Arrows = approx £15million of which about £7million is recouped from appearance fees. There is also sponsorship which eats into the £15million.
IMHO Trident is not needed and totally unjustifiable even in a period of prosperity.
In a period of stringent cuts such as we are now then to consider replacing it is downright criminal.
We have not, do not and never will ever need a nuclear capability for the purposes of "Defence of the Realm".
