The 2010 Wright Reforms are the most significant changes to the Select Committee system in the UK House of Commons since their inauguration in their modern form in 1979. We use interrupted time series techniques (ARIMA) to test the impact of the Wright Report on the level of parliamentarians’ engagement with those Select Committees covered by the Wright Reforms using proxy measures of membership attendance and turnover rates. We find little or no evidence that the Wright Report had an impact on these outcomes. In light of these findings, we argue that some of the claims made regarding the successes of Select Committees and the Wright Reforms are overblown or, at least, premature and inadequately supported by evidence, and that further reforms may be needed if the aims of the Wright Committee are to be realised more fully.
