UK Written Constitution Case Strengthened by Devolution Plans 2026

The UK written constitution debate has gained new momentum as Andy Burnham argues that devolution plans strengthen the case for a codified constitutional settlement. This shift could fundamentally alter the nation's governance structure, which has evolved over centuries without a single written document. As the UK remains one of the few major democracies lacking a written constitution, the implications are profound for regional power and national unity.

Why Devolution Plans Boost the Case for a Written Constitution

Andy Burnham, the Mayor of Greater Manchester, has been a vocal advocate for decentralisation. His recent statements suggest that the ongoing devolution of powers to regional leaders makes a written constitution increasingly necessary. By codifying the distribution of authority, a written constitution would provide clarity and permanence to the devolution arrangements that are currently ad hoc and reversible.

Burnham emphasised that as England changes through devolution, the need for a formal constitutional framework becomes more apparent. He stated, "It will increase the case for a constitution because Britain is changing through this, England is certainly changing through this." This perspective highlights the growing complexity of the UK's unwritten constitutional arrangements.

The Current State of the UK's Unwritten Constitution

The UK's constitution is famously uncodified, relying on statutes, conventions, and judicial decisions. This flexibility has allowed gradual evolution but also creates ambiguity. In contrast, most democracies have a single document that outlines fundamental principles and rights. The absence of such a document in the UK has been criticised for concentrating power in the executive and lacking safeguards for regional autonomy.

Burnham's proposed "new constitutional settlement" would aim to balance power across Wales, Scotland, Northern Ireland, and English regions. He stressed the importance of "good growth in every postcode" and equivalent living standards, which a written constitution could help guarantee.

Potential Impact of a Written Constitution on UK Governance

Introducing a written constitution would be a monumental change. According to Tim Bale, a professor of politics at Queen Mary University of London, such a move typically follows a revolution or war that delegitimises the former regime. The UK's situation is unique, as it would be a voluntary transformation driven by internal pressures for fairness and efficiency.

A written constitution could define the relationship between central and devolved governments, protect citizens' rights, and establish clear procedures for constitutional change. It might also address the "overcentralised" political establishment that Burnham criticises, shifting decision-making away from Whitehall to local authorities.

Comparison: Written vs. Unwritten Constitutions

This table illustrates the trade-offs. While a written constitution offers greater certainty and protection for devolved powers, it may reduce flexibility. The UK's current system allows rapid adaptation, but at the cost of potential instability and centralisation.

Key Takeaways from Burnham's Proposal

• Devolution strengthens the case for a written constitution by making the distribution of power more explicit.
• A new constitutional settlement could ensure equivalent living standards across all regions.
• The UK's unwritten constitution is increasingly seen as outdated and overcentralised.
• Implementing a written constitution would be a historic departure, requiring broad consensus.
• Regional leaders like Burnham are driving the conversation toward codification.

Challenges and Next Steps

Despite the growing support, the path to a written constitution is fraught with challenges. There is no consensus on what such a document should contain, and the process of drafting it could be contentious. Moreover, the UK's parliamentary sovereignty tradition makes any limitation on Parliament's power difficult to accept.

Burnham's vision, however, offers a potential roadmap. By focusing on devolution and living standards, he frames the constitution as a tool for practical improvement rather than abstract ideology. This pragmatic approach may gain traction among the public and politicians alike.

FAQ

In conclusion, Andy Burnham's advocacy for a written UK constitution, bolstered by devolution plans, marks a significant moment in British political discourse. As the nation grapples with regional inequalities and centralisation, the call for a codified settlement may resonate increasingly. Whether this leads to actual constitutional reform remains to be seen, but the debate has certainly been elevated.
