YES Scotland will be organising the biggest "get out and vote" exercise the country has ever seen by laying on coaches and mini-buses in cities across Scotland to ensure its supporters cast their votes.

Over the last few weeks and months, the pro-independence campaign has been targeting those Scots, who have rarely or never voted in elections, urging them to take part in what has been promoted as a once in a generation referendum on Scotland's future.

To this end, Yes Scotland will today target mainly highly populated and deprived areas of cities like Glasgow, Edinburgh, Dundee and Aberdeen with a fleet of two dozen or so branded campaign coaches and mini-buses to help get particularly the unemployed and elderly to the polls.

It is thought the vehicles have cost the pro-independence campaign around £150,000; the money coming from Yes Scotland's £1.8m referendum coffers.

In the last few days before the registration deadline, it was estimated some 180,000 people rushed to put their names down to vote.

The total registered number stands at 4.2m, some 97 per cent of the eligible electorate; a Scottish record, which has led to an expected high turnout of more than 80 per cent.

"Throughout this campaign, we have spoken to people who are not normally interested in politics and have encouraged them to register to vote," said a Yes Scotland spokesman. "Hopefully, they will turn out on the day and the fleet of vehicles will be there to help them with that."

He added that the coaches and mini-buses would be used to ferry "primarily Yes voters" but noted: "I don't think the drivers would turn away any No voters who had made it onto the vehicles."

Nicola Sturgeon, who described the transportation plan as the" biggest get out and vote process Scotland has ever seen", explained: "This campaign has been a celebration of democracy with people engaging in political debate in a way we have never seen before.

"There will be a massive Yes presence on the streets and on the roads as we ferry people to the polling stations in huge numbers."

The Deputy First Minister said while people who had never shown an interest in politics had signed up to vote in large numbers, the key thing now was to ensure they were able to vote.

Campaign staff will be on hand at the polling stations to explain the voting process to tens of thousands of people, many of whom may never have participated in it before.

"Research tells us that the official nature and appearance of polling stations can be intimidating for some people.

"So we're determined to overcome any individual nerves or doubts new voters have about the process," said a campaign source.

It is thought that Better Together is also planning to organise a similar get out and vote transportation exercise but no one was available to help with details.
