But untrue and more scorched earth politics.
1) It’s over 6 years, so the Tories are very unlikely to be in power to implement it.
2) Even if they were, the ‘increase’ is based on the assumption that defence spending would have remained flat in cash terms (which it really would not have done, as that would take it below the legally mandated 2% of GDP) and based this notional increase on that
3) Turns out that what the Treasury is using for this ‘increase’ is NATO qualifying defence spending, which is entirely different to the definition of defence spending announced in the Budget, but it’s the Budget figures the increase is based on.
They’ve only done this because it will force an incoming Labour government to cancel it, pending a defence review.
