Both Houses establish select committees to conduct inquiries and to produce reports on a range of matters, from the conduct of Government to specialist subject areas. Information on their work can be found on the select committee page.
Both Houses refer legislation to committees for detailed discussion and approval. These committees are part of the process of making laws and include public bill committees, delegated legislation committees and committees on private bills. There is more in Bills and Legislation.
Some other committees are established either by statute of either House, with a range of specific functions. These committees can be found through Committees A-Z.
The About Parliament section of our site provides information on the types of Parliamentary committees and their work.
