This is the single best book published on the Westminster Parliament: admirably clear, superbly researched, and brilliantly argued.' - Philip Cowley, University of Nottingham, UK.

This fully revised new edition includes expanded coverage of Parliament's relationship with the courts, devolved assemblies and the European Union. Distinctively, the book goes beyond the usual focus of Parliament-Government relations to encompass policy-makers beyond Whitehall and Parliament's broader relationship with citizens.
