Resumen de Committee Hearings of the UK Parliament: Who gives Evidence and does this Matter?

Marc Geddes

• While evidence hearings by House of Commons select committees have received increasing attention by the public and the media in recent years, academic research on this topic has remained rather thin. Drawing on both quantitative and qualitative methods, this article examines this topic. It begins by explaining why evidence is important: (i) it is fundamental to sustain detailed scrutiny; (ii) it builds individual-level and institutional-level expertise; and (iii) the range of evidence gathered is used by committees to engage with the public. The article then presents empirical data of the pool of witnesses on which committees rely, which arguably does not reflect the UK population, which raises important further questions over the representative claims of committees.
