Devolved and reserved powers in the UK

Watch this video to find out which reserved matters the UK Parliament has power over, and which devolved matters are under the control of the Scottish Parliament.

Why are there two parliaments?

Decisions about how the UK as a whole is run are made at the UK Parliament in Westminster.

The UK also has a number of devolved assemblies and parliaments:

  • Scottish Parliament
  • National Assembly for Wales
  • Northern Ireland Assembly
  • London Assembly

For Scotland, decisions about reserved matters are made at the UK Parliament as they affect the whole UK and international relations

Reserved matters include:

  • defence
  • foreign affairs
  • immigration

Decisions about devolved matters are made at the Scottish Parliament as they affect Scotland only and people who live here

Devolved matters include:

  • education
  • health
  • law and order

More powers were devolved to Scotland in the Scotland Act (2012) and Scotland Act (2016), including some power over tax, welfare and borrowing.

Disagreements about reserved and devolved powers are decided on by the UK Supreme Court.

The Prime Minister is held to account by Parliament at Prime Minister’s Questions (PMQs), which takes place every Wednesday at midday.

A new Prime Minister is appointed when the previous Prime Minister resigns. Most usually, this is when an existing Prime Minister's party is defeated at a general election.

In terms of Scotland, the Prime Minister only has power over reserved matters.
