That's probably not the poll we were mentioning earlier. It's based on the one commissioned by the Guardian although the pollsters changed their weighting as they believed they had over-sampled people who are socially conservative:

So it's a lead for Remain under the new weighting and a lead for Leave under the old one.
There is apparently another poll tonight showing Leave ahead and given the hype around it then it's probably a big one.
