Are phone polls more accurate than internet polls in the EU referendum?

It is difficult to conceive of a tougher test for political pollsters, after a year (2015) they would rather forget, than the referendum on the UK’s membership of the European Union in June 2016: a binary decision that cuts across traditional party lines with no recent equivalent vote to turn to for reference.

To make matters worse, there is currently a huge gulf between what polls conducted online and most of those administered over the phone are saying. At this rate, the political polling industry risks emerging from one post-mortem only to be plunged into the need for another.
