Welsh Labour is expected to lose its majority in the Senedd after a century of continuous electoral success [1].
The projected collapse marks a historic shift in Welsh politics, ending a long-standing era of one-party dominance in the Cardiff-based parliament.
Initial projections indicate Labour representation will fall from 29 seats to between nine and 10 members [2, 3]. This decline follows a century-long winning run in Welsh elections [1]. In contrast, Plaid Cymru has surged to win 43 seats, while Reform UK has secured 34 seats [3].
Analysis suggests the shift is driven by voter backlash over deteriorating public services and a perceived disregard from the UK Labour party [4]. These factors contributed to what has been described as an "astonishing" collapse in support [4].
"We are deeply disappointed that we will not lead the government," a Welsh Labour spokesperson said [2].
The party also expressed concern over the loss of its legislative presence. "We now expect to lose several hardworking and respected members of the Senedd," the spokesperson said [5].
The results signal a move away from the traditional political alignment of the region. While some reports focus on the loss of power after 27 years, other records highlight the broader 100-year streak of electoral victory that has now been broken [1, 3].
“"We are deeply disappointed that we will not lead the government."”
The projected loss of the Senedd majority represents a fundamental realignment of the Welsh electorate. By shifting support toward Plaid Cymru and Reform UK, voters are signaling a rejection of the established center-left consensus in favor of nationalist and right-wing alternatives, likely complicating future governance and coalition building in Cardiff.
