Senior Labour members of the Welsh Parliament have launched a blistering attack on Sir Keir Starmer's government, accusing it of actively rolling back the powers of Welsh devolution. The extraordinary intervention marks a significant internal rift within the party, just months after Labour's return to power in Westminster.
A Coordinated Rebuke from Cardiff Bay
The criticism was delivered in a formal letter, signed by a group of Labour Members of the Senedd (MSs), and sent directly to the Prime Minister. The letter, dated December 2025, expresses profound concern that the UK Labour government is centralising power and making decisions that should rightfully fall within the remit of the devolved administration in Wales.
The Welsh parliamentarians argue that this represents a direct contradiction of the party's previous commitments to strengthen and respect the devolved settlements across the UK. They claim the actions of Starmer's ministers are undermining the Senedd's authority and treating Wales with a dismissive attitude reminiscent of past Conservative governments.
Specific Grievances and Policy Clashes
The letter is not a vague expression of discontent but outlines specific policy areas where the Welsh Labour group feels sidelined. Key points of contention include decisions related to economic development, environmental targets, and public service funding. The MSs allege that Westminster is imposing its will without proper consultation, bypassing the democratic institutions in Wales.
This public airing of grievances is highly unusual, demonstrating the depth of frustration in Cardiff Bay. It suggests that the long-standing tension between the UK party leadership and its Welsh branch, often papered over during the opposition years, has now erupted into open conflict following the general election victory.
Broader Implications for the Union and Labour Unity
The fallout from this letter extends beyond internal party politics. It strikes at the heart of the UK's constitutional future and the relationship between its constituent nations. The accusation of a "rollback of devolution" is a serious charge that could fuel nationalist sentiments in Wales and complicate the UK government's dealings with the Scottish Government and Northern Ireland Executive.
For Sir Keir Starmer, who campaigned on a platform of stability and pragmatic governance, this revolt from within his own party's ranks in Wales presents a major challenge. It forces his government to publicly define its vision for the Union and devolution, a task that has proven treacherous for previous Prime Ministers.
The response from Downing Street will be closely watched. A failure to adequately address these concerns could lead to a permanent fracture within Welsh Labour and embolden those arguing for further political autonomy. This episode serves as a stark reminder that managing the complex UK constitution remains one of the most difficult tasks for any occupant of Number 10.
