So, they simply could be wrong and the online polls – which put ‘Leave’ much closer – could in fact be right. It wouldn’t be the first time. And when you then start to factor in “likely voters” the margins come down still further. In short, don’t bet on the polls just yet.

2. It’s all about the turnout.

Most pollsters agree that if everyone could vote via smartphone without getting out of bed on June 23, Britain would indeed vote to ‘remain’ by a fairly comfortable margin; perhaps even as much as 60-40.

But as we all know, the referendum result will be decided by voters who actually do bother to get out of bed and go to the polls, rather sleeping off their hangover from the previous night’s box office Euro 2016 fixture – Italy v Ireland.

Research by the University of Kent’s Matthew Goodwin has shown that a low turnout almost certainly favours a Brexit, since the pro-Leave camp supporters are much more motivated than remainers.
