This chapter discusses the administrative organization and governance of the UK Parliament — that is, the way in which the two Houses of Parliament are directed, managed, and led. More specifically, it deals with the administration or governance of services to Members of Parliament (MPs), and how that is organized. The discussion begins with an overview of the peculiar nature of Parliament as a public institution, highlighting five features which make governance and reform of governance difficult. The chapter then considers the basic structure of governance in the House of Commons and in the House of Lords, taking into account the statutory House of Commons Commission and the non-statutory House of Lords Commission, before describing contemporary developments in both Houses. It also looks at two future developments that may affect parliamentary governance and administration: the restoration and renewal of the Palace of Westminster, and the issue of shared parliamentary services.
