Those living in Scotland, with a university education or aged below 30 are most likely to want to stay in the EU, according to new polling data released by YouGov.

The UK's overall voting intentions could not be closer - with a slight lead in favour of the European Union - but splits between different groups of voters could hold the clue to the referendum's result.

While there seems to be no gender gap, the issue splits the population down age, political leanings and education.

YouGov said that its research shows that "for once the differences do match the stereotypes. There is a huge contrast between the kinds of people wanting Britain to stay in the EU and those wanting Brexit".

But what else does it indicate?

Northern Ireland and Scotland are the UK's most pro-EU regions

The survey shows that Northern Ireland and Scotland are the regions most in favour of staying in the EU, with almost two thirds of respondents wishing to remain.

The least positive region about EU membership is the Midlands - with 59 per cent of the East Midlands wanting to leave.

The figures could be crucial in the event of a “Brexit” vote as Nicola Sturgeon, Scotland's First Minister, has stated that demand for a second independence referendum could be "unstoppable" if taken out of the EU against its will.
