Constitutional watchdogs are the guardians of the system for upholding standards. The Constitution Unit has long had an interest in constitutional watchdogs, from one of our earliest reports in 1997 to one of our most recent, on parliament’s watchdogs published in 2022. The Unit published a further report on the watchdogs which regulate the executive in March 2024.

The Constitution Unit's work on constitutional watchdogs is led by Professor Robert Hazell.

Parliament's Watchdogs

This study examines watchdogs which regulate the election, remuneration and conduct of MPs, and those seeking election as MPs.

Executive Watchdogs

This project covers seven watchdogs which monitor the conduct of the executive. It makes suggestions for how they should be strengthened, and by how much.
