Devolution differs from federalism in that the devolved powers of the subnational authority ultimately reside in central government, thus the state remains, de jure, a unitary state. Legislation creating devolved parliaments or assemblies can be repealed or amended by parliament in the same way as any statute.

Legislation passed following the EU membership referendum, including the United Kingdom Internal Market Act 2020, undermines and restricts the authority of the devolved legislatures in both Scotland and Wales.[1]
