To ask the Scottish Executive, in light of the statement in Government Expenditure and Revenues in Scotland 2003-04 (GERS) that unidentifiable expenditure outside the United Kingdom was allocated to Scotland on the same basis as non-identifiable expenditure, in line with the principle that “expenditure outside the UK is non-identifiable from the perspective of the UK’s constituent countries, as the benefits are shared between them”, how much of the expenditure on the Channel Tunnel Rail Link in 2003-04 was classified in HM Treasury’s public expenditure database as being outside the UK and, of this, what proportion the Executive allocated to Scotland in GERS; how much of the expenditure on the Channel Tunnel Rail Link in 2003-04 was identifiable within the UK and, of this, what proportion was identifiable to Scotland, and whether the Executive considers the differences in proportions allocated to Scotland to be justifiable.
