Devolution is the transfer of certain powers from the UK Parliament to Scotland, Wales and Northern Ireland. This explainer covers how it works and the difference between reserved and devolved powers.
The United Kingdom is one country, but it is not governed by a single parliament alone. Scotland, Wales and Northern Ireland each have their own elected bodies making decisions on many of the matters that affect daily life. This arrangement is called devolution, and understanding it explains a great deal about how the UK actually works. Here is a clear guide.
Devolution is the transfer of specific powers from the UK Parliament at Westminster to elected institutions in Scotland, Wales and Northern Ireland. It gives each of these nations the ability to make their own decisions in defined areas, while the UK as a whole remains a single sovereign state.
The key word is transfer of specific powers. Devolution is not the same as independence, and it is not federalism. The UK Parliament remains sovereign — in principle it retains ultimate authority — but in practice it has handed substantial day-to-day responsibilities to the devolved bodies. Modern devolution in its current form was established at the end of the 1990s, following referendums, and has been expanded since.
Each nation has its own legislature and its own government:
These bodies are elected by voters in their respective nations and can pass laws and set policy in the areas devolved to them. Notably, England has no separate national parliament — laws for England are made by the UK Parliament itself.
The heart of devolution is the distinction between two kinds of power.
Devolved powers are the matters a nation can decide for itself. Reserved powers are the matters kept with the UK Parliament for the whole of the UK.
Devolved powers — decided by the nations themselves — typically include:
Reserved powers — kept at Westminster for the entire UK — typically include:
This is why your experience of, say, the health service or schools can differ depending on which UK nation you live in, while matters like defence or the value of the pound are handled UK-wide.
One of the most important features of UK devolution is that it is not uniform. The three nations do not have identical powers, because devolution developed separately for each, through different laws and at different times.
| Nation | Legislature | Notable characteristics |
|---|---|---|
| Scotland | Scottish Parliament | The broadest range of devolved powers, including significant tax powers |
| Wales | Senedd | Powers expanded over time, now including primary law-making |
| Northern Ireland | Assembly | Power-sharing Executive reflecting its specific political settlement |
This patchwork is described as asymmetric devolution. It reflects the distinct histories, identities and circumstances of each nation rather than a single master plan. It also means general statements about "devolved powers" always need a "in which nation?" attached.
A frequent source of confusion is the line between devolution and independence. The distinction is fundamental:
Questions about a nation's constitutional future — including independence — are the kind of major decision sometimes put to voters directly through a referendum. Devolution itself was originally established with public backing in referendums in the late 1990s.
Because England has no separate parliament, an imbalance sits at the centre of the system: Scottish, Welsh and Northern Irish matters are largely decided by their own bodies, but English matters are decided by the UK Parliament, in which MPs from all four nations sit. This is often called the English question, and various partial answers have been tried over the years.
Separately, there is a different layer of devolution within England: powers over areas such as transport and economic development have been passed to some city-regions and metro mayors. This is local or regional devolution rather than national devolution, but it uses the same basic idea of moving decisions closer to the people they affect. How those national decisions are decided in the first place is set out in how UK general elections work.
Devolution is the transfer of specific powers from the UK Parliament to elected bodies in Scotland, Wales and Northern Ireland, allowing each to decide matters such as health and education for itself. Powers are split between devolved (decided locally) and reserved (kept at Westminster, covering defence, foreign affairs and the economy). The system is asymmetric, with each nation holding a different range of powers, and it is distinct from independence — the nations remain part of a single United Kingdom.
