Budget cuts don't make sense

Firstly, I don't have ALL the figures, but I have pulled out most.
The totals I have don't come near to the figures promoted.
What does stick out like sore thumb are:

International Development an increase of Stg 3.7 bln which equates to +47%
Why? these are handouts to countries where most goes on corruption!

Intelligence and increase of Stg 100 mio or +4.7% when all we hear is that cyber wars and terrorist are our biggest threat!

Work and Pensions decrease Stg 9.3bln which is 9.3%

Energy and Climate change increase of Stg 800 million or +27%
Environment, food and rural affairs decrease of Stg 700 million or -24%

N.Ireland, Scotland and Wales decrease of Stg 1.1 bln or -2%
But this won't be true as Wales has announced free prescriptions so costs will rise.
Why is it that only the UK has to pay???? If we made these countries pay for prescriptions it will cut costs quite a bit.

The cuts have a certain amount of  presumption included and I can say that most of these will not be correct.

So from Stg 81bln I expect a reduction of this figure to about Stg 15 bln.
