Why did the opinions polls get it so wrong?

The failure of opinion pollsters to predict the outcome of the 2015 general election may have been because Conservative voters are harder to track down, a report has suggested.

Polling expert Professor John Curtice told the Daily Politics the polls "weren't simply interviewing enough Conservative voters - not that those voters were lying".

He recommended that, in future, there should be fewer, "more accurate" polls in the run up to elections, rather than daily offerings.
