Plaid Cymru Leads Polls for Senedd Election

Polls indicate a dramatic shift in Welsh politics ahead of the Senedd election on May 7, with Plaid Cymru projected to emerge as the largest party for the first time, potentially displacing Welsh Labour after more than two decades in power. The latest ITV YouGov survey shows Plaid Cymru leading with 33 percent of the vote, translating to an estimated 43 seats in the 96-member parliament, followed closely by Reform UK at 27 percent and around 30 seats. Welsh Labour trails at 13 percent, while the Green Party of Wales is on course for 10 seats, marking its debut representation in Cardiff Bay.

The election introduces a new proportional representation system, dividing Wales into 16 constituencies that each elect six members through successive rounds of voting. Experts note this setup heightens uncertainty, as small vote swings could reshape outcomes, particularly for mid-sized parties like the Greens. Dr. Jac Larner of the Wales Governance Centre explained that final seats often hinge on narrow margins, where a two or three percentage point shift might cascade into widespread gains or losses.
