“This works out as a swing of 6.7% from Labour to the Conservatives in Wales, larger than in most GB polls. If repeated at the general election on Thursday then on a uniform swing across Wales the Conservatives would gain four seats (Cardiff North, Vale of Glamorgan, Aberconwy and Carmarthen West & South Pembrokeshire) and Plaid Cymru would gain two (Ynys Mon and Arfon). Labour would be down 6 and the Liberal Democrats unchanged on 4.”
