Scottish Independence. Bring it on!
United Kingdom Government Expenditure.
This comprises all expenditure that can be identified as being to the benefit of a particular country. It does not, however, take account of non-identifiable expenditure, such as defence and debt interest, which are deemed to be for the benefit of the entire UK, regardless as to where the money is all actually spent.
In actual monetary figures, this would work out as (per person):
... England £7,121
... Scotland £8,623
... Wales £8,139
... Northern Ireland £9,385
The population of England is 83% of the population of the UK. Instant abolition of the Barnett Formula, based on the above figures would result on an average UK expenditure of approximately £7,362. This would be a large decrease for each person in Scotland, Wales and Northern Ireland but an increase of less than 4% per person for England.
