Below is the Druid's North Wales Poll Tracker incorporating the latest ITV Wales/YouGov survey:

As has been widely reported in the press, Labour's Welsh surge is also clearly visible in North Wales with apparently 45% of N.Wales constituency voters now backing Labour - the highest figure by some margin since the Druid started this tracker. In contrast both Tory and LibDem support has fallen, with Plaid Cymru picking up somewhat.
Frankly I think this poll is clearly an outlier, and the reason is this: according to the very same poll, 47% of people in North Wales think that either George Osborne's budget cuts are "about right" or "have not gone far enough" - the highest regional support figures of any region in Wales. Similarly, the percentage of people opposed, who think Osborne has "gone too far in trying to reduce the deficit", is just 39% - considerable below the all Wales average of 43%. Accordingly its not clear why Labour's support should have leapt over 10 points in North Wales since the general election. I fully expect to see Labour's support fall back closer to 35% in the next poll.
Regarding the question of giving the National Assembly increased law-making powers, YouGov finds that North Wales voters are the most sceptical in Wales with 35% planning to vote 'no' - compared to the all-Wales average of just 28%. Furthermore, with only 48% of N.Wales voters planning to vote 'yes', this is the second lowest support figure in Wales. This is very surprising when you consider that the BBC "Wales Devolution" poll carried out in March this year actually found that North Wales residents are much more pro-Assembly and anti-Westminster than any other part of Wales. There is clearly something wrong with either or both of these polls as both results cannot be true.
