"Devolution has strengthened rather than contained sub-national nationalism in the United Kingdom." Critically examine this in the light of the Cardiff MoU.

Devolution means Westminster passing powers by statute to Scotland, Wales and Northern Ireland. It followed the 1997–98 referendums [2][3] and was meant to hold a multi-national Union together. On 14 September 2026, the First Ministers of all three nations signed the Cardiff MoU, committing jointly to independence from the U.K. [1]. The MoU suggests that devolution has given nationalism a platform, though it has not made independence inevitable.

How devolution strengthened nationalism

• Institutional platform: in 1997, 74% of Scottish voters backed a Parliament [2]. Devolution then gave nationalist parties governments and budgets. The MoU is signed by heads of government, not by protest groups [1].
• Gradual escalation: Wales approved its Assembly by only 50.3% in 1997 [2]. Its First Minister has now signed a pledge to leave the U.K. [1].
• The Brexit shock: Northern Ireland voted Remain in 2016 [6] but left the EU anyway. The devolved governments had no say over the decade's biggest constitutional decision. This explains why the MoU asks for closer EU ties [1].
• Legal block, political response: in 2022 the U.K. Supreme Court held that an independence referendum concerns the Union, which is reserved to Westminster [5]. With the legal route closed, nationalists have turned to coordinated political pressure, and the MoU is the result.

How devolution contained nationalism

• The people's verdict: in the 2014 Scottish referendum, 55.3% voted No on a 84.6% turnout [4]. No vote has been held since to show that opinion has changed.
• Peace dividend: the Belfast Agreement's power-sharing Assembly moved Northern Ireland's conflict from violence into institutions [3].
• Sovereignty intact: the MoU is a political declaration with no legal force. The Union can be changed only by Westminster [5].
• Different goals: Scotland and Wales want independence. Northern Ireland's route is Irish unification under the Good Friday framework [1][3]. The MoU is therefore a coalition of grievances, not one movement.

Devolution worked while the Union's terms stayed fixed. It turned into a platform for nationalism once Brexit changed those terms without the devolved nations' consent. The statement is therefore only partly valid: devolution gave nationalism more reach, but it did not create it. The way forward is consent-based reform, such as a guaranteed role for devolved legislatures in constitutional change and stronger intergovernmental forums. Similarly, India's cooperative, asymmetric federalism shows that a Union lasts when it keeps renewing the consent of its parts.
