Scottish voters share similar views on Brexit as those in the rest of the UK, showing little demand for a special deal north of the border, new research suggests.

The study from NatCen Social Research found while the majority of Scots voted to stay in the European Union, their expectations on key aspects of the UK's exit deal broadly match those across Britain.

Professor John Curtice, the author of the report, said the findings call into question whether concerns over leaving the EU will boost support for independence.

The research was based on a survey of 859 Scots between February 5 and March 2, and a Britain-wide poll of 2322 people.

It came the day after the process for leaving the EU was formally triggered by the Prime Minister.

The survey found 93% of Scots are in favour of maintaining free trade with the EU after Brexit, compared with 88% across Britain.

Meanwhile, 65% of Scots think EU immigrants should be treated in the same way as non-EU immigrants, only slightly lower than 68% across Britain.

The study also suggests there is little appetite for a distinctive deal. Almost two-thirds (62%) of Scottish voters think that after Brexit, the rules on trade and immigration should be the same in Scotland as they are in the rest of the UK.

But it also found Scots are more likely than voters across the whole of Britain to accept people from the EU should be allowed to come to the UK to live and work in return for British companies being able to trade freely in the EU.

A total of 61% of Scots said the UK should "definitely" or "probably" allow free movement of people in return for free trade, compared with 54% across Britain.

The UK Government has made it clear Britain will not remain a full member of the European single market, requiring freedom of movement, and will seek a new free trade deal with the EU.

On the other hand the Scottish Government proposed special arrangements to allow Scotland to remain in the trade bloc and gain powers over areas such as immigration.

First Minister Nicola Sturgeon announced plans to call a second independence referendum after stating her proposals had been met with "intransigence".

Professor Curtice said: "Much of the debate about Brexit in Scotland has assumed voters north of the border want a much softer Brexit than voters in the rest of the UK. Indeed, the Scottish Government's demand for a second independence referendum rests on such an assumption.

"However, this first systematic study of attitudes towards Brexit in Scotland shows that for the most part voters on both sides of the border want much the same outcome - free trade, immigration control and retention of much of the consumer and environmental regulation currently afforded by the EU.

"This means that on immigration in particular, voters in Scotland seem to be more in tune with the stance taken by the UK Government than that adopted by the Scottish Government."

Scottish Conservative constitution spokesman Adam Tomkins added: "This report dismisses the myth that Scots think differently from any other part of the United Kingdom when it comes to the Brexit negotiations.

"Like the UK Government, Scots want the best deal for Scotland and the UK, and to secure the freest possible trade with the single market.

"Polls have consistently shown that there is no appetite for a second referendum, but these figures prove that there is also no demand for a differentiated deal for Scotland either."

The SNP said Scots' backing for maintaining free trade with the EU was in line with the Scottish Government's proposals to stay in the single market.

Polls have consistently shown people in Scotland prioritise the single market over restricting freedom of movement, the party added.

SNP MSP Richard Lochhead said: "People in Scotland overwhelmingly, by a 24-point margin, voted to Remain in the EU - but in even greater numbers Scots want to retain the benefits of single market membership that Theresa May is determined to abandon.

"The option of single market membership was unilaterally taken off the table by Theresa May, which is exactly why the public do not believe the Prime Minister is acting in Scotland's interests.

"Indeed, even though 93% of people in Scotland want unrestricted free trade with the single market, (Foreign Secretary) Boris Johnson has said leaving without a trade deal and reverting to hefty WTO (World Trade Organisation) tariffs would be 'perfectly OK'.

"With the UK Government completely unwilling to represent Scotland's interests, it's essential that people in Scotland are given the choice of a different future."

A Scottish Government spokesman added: "Scotland voted overwhelmingly to remain in the EU and this poll reflects Scots' enduring belief in the value of EU membership.

"The poll demonstrates people in Scotland continue to value the protections and rights offered by the EU, particularly on key issues such as free trade and freedom of movement.

"It also highlights greater support in Scotland across many important issues to maintain the benefits of EU membership, compared to the UK as a whole.

"This is also one of many surveys since the referendum that tells us a strong majority of Scots would support free movement of people, if it allowed free trade to continue between the UK and the EU.

"NatCen's poll shows 93% of Scots support maintaining free trade with the EU after the UK leaves, something the Scottish Government has explicitly called for, including through detailed proposals in Scotland's Place in Europe on how this can be achieved.

"Scots also recognise and value the role of the EU in protecting everyday rights for people and demonstrate lower levels of support for key aspects of a 'hard Brexit', such as labour market regulation.

"A number of indicators of this poll demonstrates that Scots - along with a sizeable proportion of people in the rest of Britain - continue to value the EU's role in ensuring these vital protections."

Scottish Secretary David Mundell said: "This shows that people in Scotland and across the whole UK share the same ambitions as we begin our negotiations to leave the EU.

"Today's report underlines the need for the Scottish government and the UK government to work together to secure the right deal for the whole UK."
