Quick Summary

On May 7, center-left nationalist parties in Scotland, Wales, and Northern Ireland came into power simultaneously for the first time. This week marks a significant step as leaders from these regions met in Cardiff to sign a memorandum of understanding calling on Westminster to facilitate constitutional changes that could lead to independence referendums. While this meeting was partly ceremonial, it signals a growing push for devolution within the UK, with each party having different timelines and pressures regarding their path toward potential secession.

Story summary

On September 14, 2026, leaders from Scotland (John Swinney), Wales (Rhun ap Iorwerth), and Northern Ireland (Michelle O’Neill) met in Cardiff to sign a memorandum of understanding. The agreement aims to push for referendums on independence from the UK, asserting their right to self-determination. Despite Prime Minister Andy Burnham’s earlier suggestion that another referendum could be held if there was clear consensus north of the border, Downing Street later reaffirmed its stance against such votes being "off limits." The meeting comes as all three nations now have first ministers committed to leaving the UK, with Swinney and O’Neill specifically calling for referendums while Wales' ap Iorwerth did not set a timeline.

🔮 John Healey has backed away from cutting the cost of welfare this parliament, amid dire warnings his first budget could lead to brutal spending cuts because of a £28bn shortfall in public finances.
🔮 I spoke to the Guardian’s Latin America correspondent Tom Phillips, who was in São Paulo at the Workers’ party vote count, to find out what the result means and what may lie ahead.
🔮 Emmanuel Macron has said “illegitimate” demonstrations will be banned over the coming days as France seeks to get a grip on civil unrest after some of its worst street violence in years.
🔮 For our prime minister, it’s “one of the most annoying things on public transport”: maybe you’re trying to work, or read, or you’ve finally got your kid to sleep, when someone starts blasting sound from their phone at full volume. As I sign off this First Edition en route from Glasgow to London (the things I’ve heard on this commute, against my will, I’ll save for another newsletter), I’m hoping everyone has been paying attention.
🔮 Kemi Badenoch has announced that the Conservatives would abolish inheritance tax on family homes if elected, prompting criticism that she is prioritising cutting taxes for the rich.
🔮 While Green members celebrated, or mourned, the motion passing, some have questioned its purpose, arguing it will distract from what’s important – keeping eyes on Gaza and holding the Israeli government to account – instead igniting a divisive discussion about ideology that will only harm the party. Today, I spoke to Guardian columnist Jonathan Freedland, to understand how the vote has been received by many Jewish people beyond the Greens, and senior political correspondent Peter Walker, who reported on the fallout of the vote at the party conference in Brighton at the weekend.
🔮 Later today, Donald Trump will be in the state of Nebraska to rev up supporters as he kicks off a campaign blitz of rallies ahead of the midterm elections on 3 November.
🔮 When prompted, AI chat bots will edit images to remove the hijabs from Muslim women, a violation of one of the world’s most common and visible expressions of faith.
🔮 Already there’s a sense of what action under Burnham might look like.
🔮 Key allies of Andy Burnham have warned the prime minister not to back down over his promises to put water companies under public control, after details emerged about the prime minister’s plan to give mayors more oversight of the industry.

that → sign → Wales

they → pose → photos
With each of the sister parties having a different timeline towards a referendum and its own domestic pressures, it’s tempting to dismiss this as spectacle over substance. asserted
it → have → substance
However, these first ministers are not shouting into a vacuum. asserted
ministers → shout → vacuum
They are part of a cross-national conversation in which devolution is the defining project of the UK’s still newish prime minister. asserted
devolution → define → minister
For today’s First Edition, I spoke to our Wales correspondent, Bethan McKernan, in Cardiff about why this agreement is more than a photocall, and checked in with colleagues in Scotland and Ireland for the view from there too. asserted
agreement → speak → view
Five big stories - Reform UK | Andy Burnham’s government could thwart Reform’s unprecedented £72m donations with retrospective restrictions on political donors that will include tough new residency requirements, ministers have announced. uncertain

public → sign → it
At the morning press conference Swinney and O’Neill called for immediate referendums in Scotland and Northern Ireland; ap Iorwerth declined to give a timetable. asserted

Events in Cardiff were gifted extra salience by a series of unscripted interventions over the past week. asserted
Events → gift → week
On a visit to Ireland last weekend, Donald Trump told reporters that he would “love” to see a united Ireland and it “may as well happen now”, prompting swift rebuttal from unionists on the Stormont executive and the UK government, as well as a solid gold response from SDLP leader Claire Hanna, who said: “It turns out that he isn’t as orange as he looks”. uncertain
he → tell → Hanna
Only weeks prior, Andy Burnham incensed Irish nationalists by declaring a reunification referendum was “off the table” – forgetting that it’s not his table, because the Good Friday agreement includes a provision for a border poll should it appear that the majority of Northern Irish voters want to leave the UK. asserted
majority → incense → UK
In a constitutional one-two, Burnham said last week at PMQs that a second referendum on Scottish independence could be held if a “clear consensus” emerged in favour - but swiftly self-corrected, telling an eager Swinney that such a vote was “off-limits” while he focuses on growing the economy and tackling the cost of living. uncertain
he → say → living
Nonetheless, says Bethan McKernan, “there is this sense that since Plaid Cymru won the Senedd elections in Wales in May, this is a new chapter in the Celtic struggle for independence – or breaking up the UK, depending on which way you look at it. uncertain
you → say → it
What this all means for Wales It was an acknowledgment of this momentum, then, that the meeting was held in Cardiff, where Plaid Cymru recently ended a century of Labour control of the Senedd. asserted
Cymru → mean → Senedd
Latest polling puts support for Wales to leave the UK at 32%, but growing in strength, and ap Iorwerth has been explicit that he won’t push for a referendum this term. asserted
he → put → referendum
Nevertheless, says Bethan, Plaid Cymru are “very ambitious … asserted
Cymru → say → ?
part of their agenda is to put Wales on the world map and mark Wales out as a nation that can stand on its own two feet.” asserted
that → put → feet
Now in power, the party is focusing on domestic issues, and also bracing for disruption with Reform winning more than a third of seats in the Senedd. asserted
Reform → focus → Senedd
It’s a similar scenario at Holyrood, where Reform is joint second largest party alongside Scottish Labour. asserted
Reform → ’ → Labour
Both ap Iorwerth and Swinney have been outspoken in their opposition to right wing populism and benefited at the ballot box. asserted
Iorwerth → benefit → box
There are already clear signs that Plaid Cymru has been learning from the SNP: one of their early priorities has been the Cynnal, a £10 a week child poverty payment, which is closely modelled on the successful Scottish Child Payment. … and Scotland The SNP was returned to Holyrood in May for an unprecedented fifth term, following a lacklustre campaign that mirrored voter disengagement and an unusually high level of undecideds. uncertain
that → be → undecideds
As its programme for government earlier this month failed to ignite public enthusiasm, this agreement is an opportunity for the Nationalists to “move the conversation back to their overarching aim - and have another confrontation with London,” Patrick Greenfield tells me. asserted
Greenfield → fail → me
(He’s now reporting from Edinburgh, after a memorable stint on this very newsletter). asserted
He → report → newsletter
Patrick reminds me that, while support for independence continues to hover around the 50% mark, enthusiasm among younger cohorts is higher: there’s a sense of Swinney future-proofing support for the party as Yes voters drift away from the SNP. asserted
voters → remind → SNP
And there’s the convenient diversion of attention from domestic travails, Patrick adds: the lingering scandal after former SNP chief executive Peter Murrell was jailed for embezzling party funds, demands for action as Scotland slumped in international education rankings last week, or looming public sector cuts as his government anticipates a near-£5bn gap in its finances by the end of the decade. asserted
government → ’ → decade
Ahead of the Holyrood elections, I can recall Swinney positively beaming at the “seismic” potential of three pro-independence administrations: now it has come to pass, his focus is thought to be on seeking an agreed mechanism for triggering a vote, although that wasn’t discussed yesterday. asserted
that → recall → vote
Sinn Féin can talk up the significance of the memorandum but its focus is very much on next year’s Stormont assembly elections, Rory Carroll tells me from Dublin. asserted
Carroll → talk → Dublin
Like the SNP, Sinn Féin’s popularity has slipped in recent years as public services crumble and it fail to deliver on key infrastructure pledges – but it is likely to win out against a fragmented unionist opposition. asserted
it → slip → opposition
