Welsh Labour have a huge 15 point lead over the Conservatives, according to new polling. The latest YouGov research for ITV shows that Labour are up four points from their result in 2010, when they won 30 of the 40 Westminster seats in Wales. The Tories are down just one point, the Lib Dems are down 15, UKIP are up 12 and Plaid Cyrmu’s support has remained static. The standings suggest Labour could be on course to win around 75% of the seats available.

The topline voting figures are:

Labour 40%, Conservatives 25%, UKIP 14%, Plaid Cymru 11%, Green Party 5%

The polling shows a stark contrast to Scotland, where supports for pro-independence nationalists has surged: only 5% of people think increased powers for the Welsh Assembly is one of the biggest topics of this election.

Instead, health (51%), immigration (49%) and the economy (47%) are seen as the most important election issues – roughly the same as the UK as a whole.

Plaid Cymru launched their manifesto today, but the event was overshadowed by former Plaid leader admitting that he didn’t really mind if the Welsh public voted for Labour.

Last month on LabourList, Welsh First Minister Carwyn Jones accused the Tories of waging a “war on Wales”.
