How do Select Committees work?
A Select Committee is a group of around eleven MPs from different parties whose job it is to scrutinise the work of a particular department of government.
They examine every aspect of the department's work in order to decide what inquiries to hold and calling for written evidence from the public about various issues the department is in charge of. They then gather evidence from experts in various fields, and use this information to question ministers.
Once they have gathered enough evidence, they will submit a report to the Government, who then have two months to respond. This can start a chain of further examination and debate.
