Have you a link to the actual source of that survey, rather than just a newspaper report (which I've seen in the Metro, but didn't give a link). It's just that I can't find it on the yougov website but its completely contrary to other surveys they've done very recently. I'd be interested in who funded this and how it was framed.
There are millions of pounds being spent on promoting no deal on social media at the moment, by anonymous sources. They are sophisticated and targeted campaigns, just like in the referendum. Unless we can get a grip on this issue I genuinely believe democracy is dead. This will apply to elections as well as referenda. And the fact that both leave campaigns have been found to be corrupt, but this has been swept under the carpet, doesn't bode well for this issue being successfully managed. Increasingly, democracy is a mirage.
