Andy Burnham travelled to Glasgow to sell a vision of uniform UK devolution — English-style metro mayors with tax and employment powers replicated in Scotland, Wales, and Northern Ireland. He left with polite engagement and a firm constitutional rebuke. Both John Swinney and Rhun ap Iorwerth told him the same thing: further devolution within their nations is a matter for Holyrood and the Senedd, not Westminster. The timing was loaded. Wednesday's budget extended regional devolution across England, giving mayors more power over tax revenues. Burnham framed this as an opportunity Scotland and Wales shouldn't miss. But defence secretary Wes Streeting poisoned the well before the summit even started, publicly accusing the Scottish government of hoarding powers it received from Westminster rather than passing them down to local councils. One Scottish official characterised Streeting's intervention as "lecturing us on devolution." The summit was already diminished before it began. Northern Ireland's first minister Michelle O'Neill pulled out after a political row between Sinn Féin and the DUP, depriving the talks of full four-nation representation. Burnham called her absence "disappointing" — a word that understates how difficult it is to build a UK-wide devolution framework when one nation can't get its own coalition to hold together long enough to attend a meeting. Plaid Cymru's ap Iorwerth arrived with a pointed agenda: more powers for the Welsh government itself, not for sub-national entities within Wales. He had already formally asked Burnham to give Wales the same devolved powers as Scotland. And he brought a budget grievance — the Welsh government says the budget amounts to a real-terms funding cut for Wales, which ap Iorwerth said showed Burnham was "not serious about Wales." The structural mismatch is real and under-examined. Former Welsh minister Lee Waters laid it out plainly: English "regions" cover 1.5 to 3 million people in dense urban areas. Welsh regions are far less dense, making the metro mayor model a poor transplant. Waters argued the Welsh government already performs the role Burnham envisions for metro mayors. Transposing Greater Manchester logic onto rural Wales isn't devolution — it's an English template imposed on different political geography. What's actually happening here is a three-way power contest dressed in the language of cooperation. Westminster wants to push power down past devolved governments to local authorities it can deal with directly. Devolved governments want to pull more power from Westminster while retaining control over what goes further down. And local councils — the supposed beneficiaries — have no seat at this table at all. The twenty-year pattern this reveals is familiar: every UK government discovers devolution is asymmetric and tries to standardise it. Every devolved government resists standardisation as a threat to its own authority. The result is that actual local government — the councils, the towns, the communities — remains the weakest tier in every part of the UK, squeezed between a centre that wants uniformity and devolved governments that want autonomy. Burnham may genuinely believe in localism, but the architecture of British power doesn't reward it.
