Votes summary Central Scotland Glasgow Highlands and Islands Lothian Mid Scotland and Fife North East Scotland South Scotland West Scotland Constituency seat changes compared to 2016 MSPs who lost their seats Analysis The SNP won 64 seats, falling one seat short of an overall majority. Some commentators put this down to unionists
voting tactically for Conservative, Labour and Liberal Democrat candidates. According to psephologist
John Curtice, "Denying the SNP an overall majority was, indeed, a collective effort – at least on the part of Unionist voters, who on the constituency ballot demonstrated a remarkable willingness to back whichever pro-Union party appeared to be best placed locally to defeat the SNP. [...] These patterns had a decisive impact on the outcome." This was apparent in seats like
Dumbarton, where incumbent Labour MSP
Jackie Baillie saw her 0.3% majority increased to 3.9%, whilst both the Conservative and Lib Dem vote share decreased. In
The National,
Emer O'Toole questioned whether social media adverts with "a lack of transparency over funding" may have cost the SNP key seats as well. The day before the election,
The Guardian reported that anti-independence groups and campaigners had "spent tens of thousands of pounds in the past week", including on
Facebook adverts, calling for tactical voting to prevent the SNP getting a majority. One of these groups was Scotland Matters, whose founder, Professor
Hugh Pennington said, "Across the country as a whole, tactical voting is obviously one of the ways forward to basically harm the SNP, not to put too fine a point on it." The
Scottish and Welsh Election Studies 2021, revealed on 13 June, found that around a third of Scottish voters who decided to vote differently in the run-up to the election did so to stop another party, and that 90% of those who did this did so in a bid to prevent the SNP winning the seat. Rob Johns, Professor in Politics at the
University of Essex, said: "[W]e found a lot more switching than we had expected. The polls had suggested that not much was changing and obviously the overall election result was almost eerily similar to 2016. That can mean that nobody has changed their mind or it can mean lots of people have changed their mind – but these have cancelled out as people have moved in opposing directions. We found there was quite a lot more of that than we had expected."
