Devolved Bodies in the UK

Scotland

• The Scottish Parliament (Holyrood) was established by the Scotland Act 1998. It has the power to pass primary legislation and has significant control over income tax rates and bands within Scotland.

Wales

• Senedd Cymru (the Welsh Parliament) evolved from an assembly with limited executive powers to a full legislative body. It now operates under a reserved powers model similar to Scotland, covering areas like the Welsh language, agriculture, and local government.

Northern Ireland

• The Northern Ireland Assembly (Stormont) is unique due to its Power-Sharing (consociational) requirement. To ensure stability between unionist and nationalist communities, the executive must include representatives from both sides, and certain decisions require cross-community support.

• The Barnett Formula is the mathematical mechanism used by the UK Treasury to adjust the amounts of public expenditure allocated to the devolved administrations. It ensures that changes in spending in England result in proportional changes for Scotland, Wales, and Northern Ireland.

• The formula is calculated based on three factors: the change in planned spending by UK government departments, the extent to which that spending is on a 'comparable' service (one that is devolved), and the population proportion of the devolved nation relative to England.

• Conceptual Formula: $\Delta \text{Grant} = \Delta \text{English Spending} \times \text{Comparability Percentage} \times \text{Population Proportion}$

• It is critical to distinguish between a devolved system and a federal system (like the United States or Germany). In a federal system, power is divided by a constitution that cannot be easily changed by one level of government alone.

• The Sewel Convention states that the UK Parliament will 'normally' not legislate on devolved matters without the consent of the devolved legislature. While politically significant, it is not legally binding in the same way a constitutional division of power would be.

• Identify the Model: When discussing powers, always check if the system uses a 'Reserved Powers' model (everything is devolved unless stated) or a 'Conferred Powers' model (only specific things are devolved).

• The West Lothian Question: Be prepared to discuss the anomaly where MPs from devolved nations can vote on laws affecting only England, while English MPs cannot vote on those same issues for the devolved nations.

• Common Mistake: Do not assume 'Devolution' means 'Independence.' Devolved bodies operate within the framework of the UK state and do not have the power to conduct independent foreign policy or declare independence unilaterally.

• Verify Scope: If a question asks about a specific policy (e.g., nuclear energy or social security), verify if it is reserved or devolved, as this varies slightly between the three nations.
