Whilst announcing the money for the 11 Gp bunker enabled Osbourne to clap himself on the back (something at which politicos seem to excel), when I visited it 4 years ago it did not look in any worse nick than other MoD real estate!
Surprised there has been no comment on the fact that, in order to reach the NATO 2% of GDP target, Osborne is resorting to some financial chicanery, eg including elements of intel spend, and also UN peace keeping costs (presumably previously in the FO budget).
