Abstract
This paper explains how the UK government sets its annual budgets within the context of multi-year spending reviews, yet was able to announce policies in the 2011 annual budget that sat outside the 2010 spending review framework. As such, it illustrates that the budget process remains an enabler of changing circumstances and is not constrained by medium-term financial planning. This finding has implications for other jurisdictions that may be considering how best to balance annual flexibility with multi-year stability in public spending.
