Why did everybody call the election wrong?

Why did everybody call the election wrong? As the dust settles on the results of the UK general election, why did everybody call it so wrong? Right until the night of the election, Ladbrokes had a Conservative majority all the way down at 9/1, with a Labour minority government the bookies' pick. In the event, Labour took a thumping in the polls, with leader Ed Miliband promptly resigning, along with UKIP's Nigel Farage and the Lib Dem's Nick Clegg. We ask InvaTrust's David Harris what we should expect next from this new Conservative majority government. #Conservatives #Elections
