Westminster’s time is ending, devolved leaders warn UK government

The leaders of Plaid Cymru, the SNP and Sinn Féin have issued a joint warning that Westminster’s grip on political power across the British Isles is loosening — and that the UK government had better start preparing for what comes next.

Rhun ap Iorwerth, Stephen Flynn and Michelle O’Neill appeared together on Tuesday to argue that the constitutional settlement holding the United Kingdom together is no longer fit for purpose. The three leaders, representing Wales, Scotland and Northern Ireland respectively, said decades of centralised decision-making in London have failed their nations and that a fundamental rethink is overdue.

It’s a message that Downing Street will find uncomfortable. But it’s not entirely surprising. Support for Welsh independence has climbed to around 35 percent in recent polls, while Scottish independence has hovered close to the 50 percent mark for several years. In Northern Ireland, a majority now consistently tells pollsters it expects a border poll on reunification within a generation.

A coordinated challenge to London’s authority

What made Tuesday’s intervention notable wasn’t any single statement. It was the coordination. Three parties from three different constitutional traditions — one seeking independence within the EU, one pursuing a united Ireland, one navigating the complexities of devolved Welsh politics — standing on the same platform with the same core message.

“The people of our nations deserve more than Westminster can offer them,” said a spokesperson for the joint group following the press conference. “That’s not a threat. That’s a democratic reality.”

Still, the UK government has so far shown little appetite for engaging with these demands. A spokesperson for the Cabinet Office said ministers remained committed to the integrity of the United Kingdom and pointed to £3.8 billion in additional Barnett formula funding allocated to devolved governments in the last financial year.

But money, the three leaders argued, isn’t the point.

What constitutional change could actually look like

The specifics of what the leaders are calling for differ significantly. Sinn Féin wants a date set for a border poll under the terms of the Good Friday Agreement, which legally obliges the Secretary of State for Northern Ireland to call one if a majority appears likely to support reunification. The SNP wants a fresh independence referendum after being blocked from holding one since 2014. Plaid Cymru is pushing for greater fiscal powers and, eventually, full independence.

Yet the three share a diagnosis even if they don’t share a prescription. They believe the devolution settlements of the late 1990s — which gave Scotland its parliament in 1999, Wales its assembly in the same year, and Northern Ireland its power-sharing executive — were never meant to be the final word.

Whether Westminster agrees or not, this conversation isn’t going away. And with elections in all three nations due before 2027, the pressure on the UK government to respond is only going to grow.
