For a hundred years, Labour ran Wales as if it owned the place. Generation after generation, the red rosette was less a party than a habit. At the 2026 Senedd election, that habit finally broke — and it broke spectacularly.
100 Years, Gone in One Night
Welsh Labour suffered a historic defeat that ended a century of Labour control of Wales. This was not a bad night to be shrugged off and recovered from at the next election. This was the end of an era. The party that took Welsh voters for granted for a hundred years was told, in the clearest possible terms, that the arrangement is over.
Third Place — Behind Plaid and Reform
And here is the detail that tells you everything. Labour did not come a respectable second. They came third — behind a governing Plaid Cymru and behind Reform UK, who are now the official opposition in the Senedd. The natural party of Welsh government is now the third party of Welsh politics, looking up at a Reform UK movement that did not even hold a seat there a few years ago.
That is not a protest vote. That is a realignment. Working people across the South Wales valleys and the towns Labour assumed were theirs forever have looked at what they were being offered and chosen something different.
It Wasn't Just Wales
Wales was the headline, but the story was national. At the 2026 local elections Labour lost control of around 35 councils and close to 1,500 councillors. In Westminster the wheels came off in public: more than 95 Labour MPs called on the Prime Minister to go or to set out a date for going, a Cabinet minister and several junior ministers resigned, and the Government spent the spring fighting for its own survival rather than governing the country.
This is what happens when a party stops listening. They promised change, delivered higher taxes and broken borders, and lectured the public for noticing. The voters returned the verdict.
What Comes Next
For Reform UK, becoming the official opposition in Wales is not a finishing line — it is a starting block. It is a responsibility. It means turning up, holding the new government to account, and proving that we can do the serious work of opposition as seriously as we fought the campaign. The voters who lent us their trust will be watching to see that we earn it.
A century of one-party dominance in Wales is over. What replaces it is up to us to build — and we intend to build something worthy of the trust we have been given.
