What motivates MPs to serve on oversight-focused select committees? This study investigates assignments in British House of Commons select committees during 2005-15. We developed a unique dataset tracking committee placements across two parliaments.
Data & Methods:
* Original assignment records from the 2005–10 and 2010–15 Parliaments.
* Surveys capturing MPs' long-term policy interests.
* Analysis using logistic regression models comparing partisan vs. informational predictions.
Key Finding:
Our analysis reveals that MPs' persistent policy interests are a dominant driver behind select committee assignments – far more influential than partisan considerations.
This result challenges the expectation that party loyalty would dictate these placements and suggests Wright reforms have reinforced this non-partisan assignment mechanism. By demonstrating how long-standing legislative concerns shape committee memberships, our findings highlight the informational logic underlying British parliamentary oversight politics.
