The SNP spent £90,830 campaigning against Brexit during the European Union referendum, new figures have shown.

The party has been accused of treating the referendum "like it was a council by-election" by the Scottish Conservatives after the Electoral Commission published the latest spending figures.

During the referendum the SNP were permitted to spend up to £700,000 on campaigning.

The SNP spent a total of £1,298,627 in its campaign for a Yes vote during the 2014 independence referendum.

The largest single spend by the party in the campaign to stop Brexit was £23,087 on a leaflet to voters entitled "You and your family are better off in Europe". A total of 1.75 million leaflets were printed.

Bob Posner, the commission's director of political finance, said: "The information we have published today provides a first chance to see the amounts of spending by many of the campaigners at the referendum.

"The publication of this data is vital in ensuring transparency and accountability, both in how campaigners obtained funds as well as how they spent them."

The Scottish Government declined to publish and print leaflets to voters during the EU referendum.

In August 2014, the government spent £550,000 distributing material in support of independence to voters.

Last week the Scottish Government spent £3542.41 printing 500 copies of a document which outlines Scotland's historical links with continental Europe.

In July, First Minister Nicola Sturgeon described how she felt when Leave clinched victory on referendum nigh.

She said: "Others, like me, will have watched events unfold right through the night and many, again like me, will have experienced a horrible, sinking feeling as the early results started to come in.

"I told the Scottish Parliament a few days later that I was 'disappointed and concerned' by the result.

"I have to admit that was parliamentary language for a much stronger feeling.

"I felt angry that Scotland faced the prospect of being taken out of the EU against our will - with all of the damaging consequences that would entail."

Conservative MSP Murdo Fraser said: "The SNP is behaving like leaving the EU is the end of the world for Scotland.

"But the party's pitiful investment in the campaign tells another story completely.

"The SNP is not a poor organisation yet it treated the EU referendum like it was a council by-election.

"Now we know Alex Neil and other senior SNP figures wanted Brexit, perhaps that explains why such little effort and cash was invested."

Scottish Liberal Democrat leader Willie Rennie said: "That the SNP would spend more on a parliamentary by-election than their national referendum reveals the low priority that they gave the referendum.

"They hardly lifted a finger during the referendum."

The Liberal Democrats are yet to publish their spending from the referendum campaign.

Scottish Labour also criticised the SNP for its level of spending on the campaign to stop Brexit.

Labour MSP Lewis Macdonald said: "People will be surprised that the SNP spent so little on the EU referendum campaign, despite being funded by multi-millionaires. As is often the case, when it comes to delivering on their warm words the Nationalists are found wanting."

He cotninued: "The Nationalists barely lifted a finger during the EU referendum but now want to take advantage of Brexit by forcing another independence referendum on the people of Scotland. This would be an act of economic vandalism. Scottish Labour will oppose any attempt to force through another independence referendum and will always stand up for Scotland's place in the UK."

An SNP spokeswoman said: "The SNP ran a strong, positive and effective campaign, helping to successfully secure the overwhelming 62% vote for Remain in Scotland.

"It's time Willie Rennie revealed how much the Lib Dems spent on their campaign in Scotland and, more importantly, if he will support our proposals to keep Scotland in the single market even if the rest of the UK leaves."

The First Minister reaffirmed the possibility of Brexit leading to Scottish independence in Dublin on Tuesday.

She told members of the upper house of the Irish parliament that a second referendum remains "firmly on the table".

The Scottish Government has drafted legislation for a fresh referendum on independence it has launched a public consultation on the proposals.
