The relationship that has developed between Parliament and citizen in the United Kingdom has been two-way and multi-faceted. This article examines the input achieved by citizen (as voter, constituent, and member of organised interest) through party, the MP, and the institution; and the output of Parliament to citizen through party, MP, and its own resources.

Citizens continue to distinguish between the local MP and the institution of which the MP is a member.
