Reform UK and Plaid Cymru neck-and-neck at 37-36 seats as Labour’s vote share collapses to 13%

Wales's political landscape faces a significant and unprecedented realignment ahead of the next Senedd election. New projections detail major shifts in party fortunes, challenging long-established power structures within the Welsh parliament and suggesting a more diverse political assembly.

Reform UK and Plaid Cymru are projected to secure 37 and 36 seats respectively in the central estimate. This places both parties in a tight contest for the largest number of seats within the Senedd, Wales’s devolved legislative body, signaling a potential shift in the overall balance of power.

Labour faces a substantial and historic decline, with its vote share forecast to drop to 13%. This represents a 23-point decrease from the 2021 election, ending the party's century-long dominance in Welsh politics and marking its lowest projected vote share since 1906.

The Conservative Party also faces considerable losses. Projections suggest they will hold only three seats, a sharp reduction from 26 in 2021. This outcome places them below the five-seat threshold required to form a Senedd political group, which offers specific parliamentary rights such as representation on committees and dedicated funding.

These projections signal a fragmented Senedd, where no single party is likely to achieve an outright majority of the 96 available seats. The significant drop in support for both Labour and the Conservatives reshapes the traditional two-party dynamic in Wales, opening the door for broader coalition discussions or minority governments.

The prospect of forming a stable government will depend heavily on inter-party cooperation. Leaders will need to navigate complex negotiations to build alliances and pass legislation, a scenario less common in previous Senedd terms. This shift could lead to more dynamic, but potentially less predictable, governance.

Observers will now closely monitor how parties adapt their strategies, seek alliances, and present their vision for governance in this evolving political environment as the election cycle progresses.
