THE SNP may have lost target seats because pro-Union groups spent tens of thousands of pounds on digital ads pushing tactical voting, an investigation has revealed. The SNP and Scottish Greens won a total of 72 seats in Holyrood on a record turnout for the Scottish Parliament elections of 63% – 10% higher than the previous average. But an OpenDemocracy report found the party could have lost key seats, which prevented them from achieving an outright majority, due to social media adverts with a lack of transparency over funding. The site found a group called Young Unionists spent more than £20,000 on Facebook ads, including more than £5000 in the final days of the campaign. Tens of thousands of voters were pushed to the VoteUnion tactical voting tool.
