§ Mr. Stephen O'Brien
To ask the Chancellor of the Exchequer what procedures are in place to ensure that revenue underspend by other Government Departments are(a) recognised by HM Treasury and (b) factored into decision making in future spending reviews. 
§ Mr. Boateng
Spending is monitored by the Treasury. The End Year Flexibility (EYF) system allows Departments to carry forward unspent budgets within departmental expenditure limits. Departments' EYF entitlements are published every year in the Public Expenditure Outturn White Paper. Departmental allocations in the Spending Review take account of all relevant factors.
