The Commons Library is the House of Commons research service. It publishes impartial briefings and explainers to support parliamentary work and inform the public. Commons Library material is useful for background context, but should be distinguished from formal parliamentary records such as Hansard, Votes in Parliament and Bills before Parliament.
