As you'll remember, the Leave campaign took the lead in a telephone poll last week. That was a genuinely sensational result, because all previous telephone polls had put Remain ahead by either a substantial or enormous margin. The snag was that the new poll was carried out by ORB, who hadn't previously conducted an EU referendum poll by telephone. So there were no baseline figures to work from, and it wasn't entirely clear whether there was some sort of ORB 'house effect' favouring Leave, or whether Remain's big lead in telephone polls had genuinely evaporated. The first evidence today from a non-ORB telephone poll suggests that it may be a bit of both. ComRes still have Remain ahead, but the lead has slumped to its lowest level to date, and Leave now appear to be firmly within striking distance.
Should the United Kingdom remain a member of the European Union or leave the European Union?
Remain 48% (-3)
Leave 41% (+2)
Leave 41% (+2)
There's still a missing piece in the jigsaw, though. ComRes first reported significant slippage in the Remain lead a good few weeks ago, and yet the only Ipsos-Mori telephone poll since then showed business as usual. Logically, you'd think that the next Ipsos-Mori poll would be bound to finally start picking up the same trend as ComRes, but if it doesn't we'll be left scratching our heads slightly (and not for the first time).
Online polls have of course been showing much more favourable results for Leave all along. That wouldn't necessarily stop them showing the same direction of travel as phone polls, but it's extremely unclear whether that's happening at the moment. ICM appear to have detected a small swing to Leave in recent weeks, but the last batch of YouGov polls (which admittedly were quite a while ago now) suggested that it was Remain that had made some progress.
And we don't have any post-Brussels polls yet, so for all we know the entire state of play may have been rapidly transformed by yesterday's horrific events. It's hard to know which side that might benefit - if there's an urge to show solidarity with Belgium and France, that ought to work in Remain's favour, but of course anything that promotes irrational fear of immigration might be expected to boost Leave. We'll just have to wait and see.
I'll calculate the Poll of Polls update later, but I've no doubt at all that the 50/50 online/telephone average will show the Remain lead at a new all-time low.
UPDATE : In fact, it's pretty extraordinary - the telephone and online averages have more or less converged. That's very likely to be a freakish finding, because there are only two polls in the telephone sample, and one of them is the ultra-Leave-friendly ORB poll. But the rules are the rules.

(The Poll of Polls takes account of all polls that were conducted at least partly within the last month. The online average is based on ten polls - four from YouGov, four from ICM, one from ORB and one from TNS. The telephone average is based on two polls - one from ComRes and one from ORB.)
