evidence: - For Scotland, Wales and Northern Ireland, Table A.21 shows the relative contributions of the devolved administrations, Whitehall departments and local government under each functional heading. This table covers the latest outturn year only. [...] In order to provide information on the allocation of expenditure split by Scotland, Wales, Northern Ireland and the English regions, the Treasury asks UK government departments and devolved administrations to undertake an annual statistical exercise. This is based on expenditure data published in July each year in HM Treasury’s Public Spending Statistics release. [...] Accompanying this release is a spreadsheet which sets out the methods which have been used to assign spending to Scotland, Wales, Northern Ireland and the English regions. All segments with expenditure (or income) of £10 million or more in 2022-23 have been included. This covers over 99% of identifiable expenditure in that year. This should increase transparency for users and provide a basis going forward for departments and HM Treasury to monitor and improve the methodologies being used.
