Works of authority on the United Kingdom constitution
Works of authority on the United Kingdom constitution are books written by constitutional theorists that are considered to be authoritative guides to the UK constitution. The United Kingdom has no written overall Constitution, thus these are guides as to the rules and customs of the land. They can be adopted or overridden by acts of Parliament.
The most prominent works of authority are:
The former two are now historical, while the latter two are regularly updated to reflect developments in parliamentary procedure.
