Devolution: Scotland, Wales, and Northern Ireland
How power is shared between Westminster and the devolved governments in Edinburgh, Cardiff, and Belfast.
What Is Devolution?
Devolution is the transfer of powers from the UK Parliament at Westminster to elected bodies in Scotland, Wales, and Northern Ireland. Crucially, sovereignty remains with Westminster — devolved powers are granted, not inherent, and could in theory be withdrawn. This distinguishes devolution from federalism, where sub-national units have constitutionally guaranteed powers.
The Scottish Parliament (Holyrood), the Senedd (Welsh Parliament), and the Northern Ireland Assembly each have different powers, reflecting different political histories. Scotland has the broadest devolution, including control over health, education, justice, some tax-varying powers, and policing. Wales has progressively gained powers but has less fiscal autonomy. Northern Ireland's devolution is tied to the 1998 Good Friday Agreement and includes mandatory power-sharing between unionist and nationalist communities.
