Abstract
This chapter examines the way the UK Parliament is administered and organized in terms of the support offered by the institution to Members of Parliament (MPs) and peers to fulfil their parliamentary, political, and policy functions. The House of Commons employs roughly 2,500 and the House of Lords around 500 members of staff, in addition to staff in the bicameral Parliamentary Digital Service. These staff provide invaluable and impartial support to Parliament. This chapter considers the political and non-political sources of support provided to MPs and peers in carrying out their role and how the resources available to parliamentarians have increased over the past two decades through a range of parliamentary reforms. It also discusses key issues and debates arising from the support given to MPs and peers, including the issue over whether staff exist to serve the institution of Parliament or to support parliamentarians.
