14 Mar 2017

This report presents original research data on delegated legislation in the 2015-16 parliamentary session. In doing so, it seeks to plug the statistical hole that exists in the understanding of the delegated legislation process, for parliamentarians, officials and observers alike.

This 2017 research report in our Westminster Lens data series builds on our 2014 study The Devil is in the Detail: Parliament and Delegated Legislation. That study laid bare the complexities, weaknesses and contradictions in the delegated legislation scrutiny process, in the first comprehensive study of this process in decades.

This report on delegated legislation in the 2015-16 parliamentary session shines further light on the process by providing detailed original data on the types of delegated powers used, the types, volume and flow of delegated legislation, the amount of parliamentary scrutiny to which Statutory Instruments were subject during the session, and the results of the parliamentary scrutiny process. The report thus furnishes essential data to improve the quality of the political debate around the rights and wrongs of delegated legislation and its scrutiny.

Submissions / Written Parliamentary Questions - Our evidence to the House of Commons Procedure Committee

The use of Written Parliamentary Questions (WPQs) is rising sharply. Since July 2024, MPs have tabled questions at unprecedented levels. By late 2025 MPs were tabling over 600 per sitting day, more than double the long-term average. WPQs are a cornerstone of parliamentary scrutiny, helping MPs obtain information, challenge government policy and put issues on the public record. But this surge raises important questions about how Parliament balances transparency and accountability with the practical limits of the system. The House of Commons Procedure Committee is now examining the issue and has just published our submission containing our latest data and analysis.

News / Mandelson, Andrew and Epstein: Should there be parliamentary committee of inquiry? A conversation with Tom Tugendhat MP - Parliament Matters podcast, Episode 133

After the Greens’ Gorton and Denton by-election win, we assess the fallout: pressure on the Prime Minister, possible party-switching, shifting alliances, and whether mainstream parties’ sub-30% vote share could revive electoral reform.
