Andy Burnham, the UK Prime Minister, says Britain needs a written constitution, linking the idea to recent efforts to advance devolution. Multiple reports describe Burnham’s position as part of a broader push to set clearer constitutional rules and reflect powers allocated across the UK. The Independent adds that Burnham first raised the same proposal in his 2024 book, “Head North: A Rallying Cry for a More Equal Britain,” where he argues for a written constitutional settlement. Other coverage reiterates that devolution remains central to his argument, suggesting that written constitutional arrangements would better define the roles of different institutions and governments. The reports do not indicate immediate legislative steps or a specific timeline for how a written constitution would be produced. Overall, the coverage presents Burnham’s comments as a renewed call for constitutional reform following devolution-related developments, while also noting the proposal has been part of his platform since at least 2024.
