Five years ago, the suggestion that a Reform UK MS would sit in Cardiff Bay would have been treated as fantasy. The suggestion that Reform would tie Scottish Labour for second place in Holyrood would have been treated as a joke. This May, both happened in the same week.

In the Scottish Parliament election on 7 May 2026, Reform UK returned 17 MSPs — joint-second largest with Scottish Labour, behind only the SNP. In the Welsh Senedd election that followed, the party returned 34 of the 96 seats up for election. Welsh Labour, which had governed Cardiff Bay continuously for nearly a hundred years, was wiped out.

One Hundred Years of Welsh Labour, Gone

The result in Wales is not a swing. It is a verdict. From the South Wales Valleys to the North Wales coast, voters did what English voters had already done at the locals — they refused to keep voting for a party that gave them stagnation, lectured them on identity, and called them bigots for noticing.

Eluned Morgan, the outgoing First Minister, lost her own seat. That doesn't happen by accident. That happens when a party has spent decades taking its heartlands for granted and the heartlands finally take their vote elsewhere.

Scotland Joins the Revolt

North of the border, the picture is just as striking. Seventeen Reform MSPs in Holyrood would have been laughed at as a forecast a year ago. It is now the printed result. Scottish Labour — once the only force that could challenge the SNP — finds itself tied with a party most Scottish commentators had spent years ridiculing.

The SNP held on, but as a fading first place rather than a dominant force. The real story is that the Scottish electorate is no longer captive to a binary of SNP versus Labour. The right-of-centre vote, abandoned for two decades, finally has a serious home.

What This Means for Westminster

Reform UK is no longer a single-issue protest. It is a national political project with elected representatives in every nation of the United Kingdom — councillors across England, MSs in Cardiff, MSPs in Edinburgh, MPs in the Commons. The Westminster establishment can no longer pretend Reform is an English curiosity.

It also reframes the next general election. The Labour assumption — that Wales delivers seats automatically, that Scotland is a swing-back story — has been demolished. Labour MPs in Cardiff, Newport, Wrexham, Glasgow and the Central Belt will be looking at their own majorities and asking exactly the wrong questions of their own leadership.

Earning the Trust, Not Just the Vote

None of this is a finishing line. Reform UK now has to govern, scrutinise and deliver across three legislatures and hundreds of council chambers. The party that promises lower council tax has to deliver lower council tax. The party that promises to slash waste has to slash waste. The party that promises to end the immigration madness has to use every legal lever on every council, in every devolved chamber, to do it.

That is the right standard. That is the standard Reform asked the voters to hold us to. And that is the standard a Reform councillor — like the one writing this — intends to meet.

One hundred years of Welsh Labour dominance ended this month. So did the Scottish Labour assumption of automatic second place. The political map of Britain has not looked like this in living memory. The next chapter is ours to write.
