Make a request for information and research
MPs and those who work for them can request information and research from our team
of subject specialists. Our specialists answer requests related to legislation, policies, constituency-level statistics and more.
All requests are confidential. We do not share requests or responses with anyone outside of our service, including other MPs and their staff.
More information about this service, including how to submit a request and our fair use policy, is available on the parliamentary intranet.
