This week’s ORB poll sends mixed signals about voters’ thinking on the EU referendum.

While topline figures suggest the Remain campaign has improved its vote share advantage over the Leave campaign among the population as a whole since last week, among those definite to vote the opposite is true – with the Leave campaign narrowing the gap among those certain to vote.

Whether this week’s change primarily is due to increased sample volatility in last week’s ORB poll because of the bank holiday weekend, or whether it represents a true change in the public’s attitudes, only time will tell.

But it demonstrates that when considering polls it is always important to focus on the broad trends and what these show, rather than the latest ‘interesting’ change.
