There are also signs that the Conservative infighting, which has characterised the referendum campaign, is now hurting the Conservatives in the Westminster stakes. The Tories are down two points on the month in the long-running Guardian/ICM telephone poll series, running at 34%, only a single point ahead of Jeremy Corbyn’s Labour party, which gains one on the month to hit 33%.
The mood at Westminster has recently turned especially bleak among Labour MPs, concerned that the party’s arguments for remaining in Europe are not connecting with its own voters. The latest telephone poll suggests that remain is still the preferred choice of Labour voters, by 58% to 38%.
However, this balance is not sufficiently emphatic to overpower the combination of a slight 49%-47% edge for leave among the Tories, and a crushing 97% to 2% preference for leave among Ukip supporters.
Breaking down the population between generations confirms that Eurosceptism sets in with age: among the young, aged 18 to 34, the balance is 56% to 39% for remaining, whereas pensioners of 65 and over lean, by 55% to 39%, the other way.
Voters in professional “AB” grade occupations are, by 57% to 38%, strongly in favour of staying in Europe, whereas skilled manual workers – the so-called C2s – are plumping for leave by an emphatic 67% to 29%.
