Seems obvious to me
The bill is too huge and it's effectiveness is highly dubious.
However the idea of the UK independant nuclear deterrant is deeply embedded in the Tory psyche. They associate it with national pride and their view of Britain as still being a great power.
You hear lots of expressions like it "giving us a seat at the top table" and things like that.
Clearly the Government is not about to cough up the cash but hasn't the guts to come out and cancel it.
Let's hope there isn't a nasty accident with aging subs held together with sticking tape eh?
Wonder what the tabloids will make of this - I know what the headlines would have been if a Labour PM had made this decision!
