YouGov/Sun - CON 32, LAB 38, LD 10, UKIP 13

This morning's YouGov poll for the Sun had topline figures of CON 32%, LAB 38%, LDEM 10%, UKIP 13%. The six point Labour lead is their lowest from YouGov since the local elections (and equals the lowest this year - YouGov had a six point Labour lead and the beginning of May and a couple in January). As ever, don't get too excited over a single poll, but it is in line with Labour's average lead with YouGov now being in the high single figures. Full tabs are here.

Also out yesterday was some polling of Conservative party members for Tim Bale and Paul Webb. The results yesterday just covered approval and attitudes towards the European Union. As things stand Conservative party members are overwhelmingly in favour of withdrawal from the European Union, by 71% to 20%. However, asked how they would vote if David Cameron secured renegotiation and recommended people vote to stay in, 54% would vote to stay, 38% to leave.

I'd take two things away from that. The first is that many Conservative party members are still open to persuasion - if Cameron managed to renegotiate Britain's membership in some way they could be persuaded to back him (though of course, it would very much depend on what Cameron managed to secure). The second is that many others aren't, even in the scenario of Cameron's successfully renegotiating powers (and that itself is a serious challenge), 4 in 10 of Conservative members would not vote with him in a referendum. If a referendum does ever happen, and if the Conservative leadership are campaigning to stay in, it really is going to open up a gulf between the leadership and some party members. Full tabs are here.
