Scotland in Union

Online, SIU maintains a website, a Facebook page, a Twitter/X account, an Instagram account, LinkedIn, as well as having a presence on more recently created social media platforms such as Threads, Mastodon and Bluesky. Social media is where SIU engage with supporters and encourage others to join their campaign.

On their website, SIU publishes updates, requests donations and highlights specific campaigns like petitions, local by elections or tactical voting campaigns and nationwide elections.

SIU has commissioned opinion polling on Scottish independence on several occasions, with a particular focus on the question of whether people think Scotland should remain part of the United Kingdom or leave the United Kingdom.[6] In 2021, three political academics carried out a study which demonstrated a statistically significant difference between the Remain / Leave format and the 2014 Yes / No question formulation.[7] Another test of the effect of the question wording was carried out via a YouGov poll in March 2022, in which the sample was split and half were asked the 2014 Yes / No question and half were asked a Remain / Leave question; this poll found a significant difference in support for remaining in the UK, depending on the question asked.[8] The use of this wording has been criticised by SNP depute leader Keith Brown, who said in 2019 that it was "a deliberate bid to confuse independence with Brexit".[9] The most recent polling using Remain / Leave at the time of writing, which was conducted in September 2022 and December 2022, indicates that 59% of Scots would vote to remain and 41% would vote to leave, once undecideds are removed.[10][11]

Polling commissioned by SIU has also asked when people think another referendum on Scotland leaving the UK should be held, if at all; and has asked people about priority areas for Scottish politicians. One example of this was a poll in May 2022 which found that only 29% of Scots wanted another referendum before the end of 2023.[12] Another poll in September 2022 found that only 7 per cent of Scots think independence is among the most important issues for the Scottish Government.[13]

Other questions asked in SIU's polling have focused on defence and international affairs. This polling in May 2022 showed that majorities believe that membership of the G7 (79%), NATO (82%) and the UN Security Council (79%) is important. Participants were also asked if the UK should retain its Independent nuclear deterrent, with 58% saying the UK should; while 20% said the UK should not (23% don't know).[14][15]

To coincide with the annual publication of the Government Expenditure and Revenue Scotland figures, known as GERS, SIU introduced a new method to break down the 'UK dividend' from which Scotland benefits,[16] for local communities across Scotland.[17] In addition, SIU's Chief Executive, Pamela Nash, has written articles to highlight the benefits to Scottish public spending which come from sharing across the UK.[18][19]

SIU has also highlighted the Scottish Government's Export Statistics Scotland publication,[20] to increase awareness of the proportion of Scotland's trade with the rest of the UK and to call for more open acknowledgement of Scotland's trade situation.[21]

In late 2022, after the UK Supreme Court had ruled that the Scottish Parliament does not have the power to legislate for a referendum on Scottish independence,[22] SIU launched a campaign to demonstrate alternative uses for the £20m the SNP administration was still apparently allocating to a referendum in 2023.[23] After the SNP announced that the £20m was in fact being diverted to the fuel insecurity fund, which was one of the suggestions SIU had made, this change was welcomed by SIU's Chief Executive.[24]

SIU also launched a 'End The Spend' petition calling on the SNP government to stop wasting taxpayer money trying to break up the UK.[25]

SIU's first campaign was to encourage tactical voting against the Scottish National Party during the 2015 UK general election.[26]

SIU also encouraged tactical voting in the 2016 Scottish Parliament election, and in November 2019, SIU launched an online tactical voting guide for Scottish voters in the run up to the 2019 UK general election. This guide suggested which party people should vote for in their constituency if their priority was to stop the SNP.[27]

In the run up to the 2021 Scottish Parliament election, SIU launched its tactical voting campaign for voters whose priority was stopping an SNP majority and another referendum. An SNP majority was stopped, with Sir John Curtice commenting that tactical voting probably played a part in this outcome.[28] According to a Scottish Election Study by academics across the UK, released in May 2022, "significant numbers of people voted for both the Conservatives and Labour as part of efforts to defeat the SNP and strengthen the Union".[29]

SIU has run a series of campaigns to highlight poor performance by nationalist administrations. These have mostly used data obtained via Freedom of Information (Scotland) Act 2002 requests, and have included items covering health and income inequalities[30][31] and cancer waiting times.[32]

In January 2023, SIU released polling (conducted in December 2022), showing that most people in Scotland think the SNP is performing poorly in its handling of key public services.[33]

SIU has used billboards on several occasions, including in 2016, when SIU paid for a large billboard advert near the SNP conference in Glasgow, urging Nicola Sturgeon to "change the record" on independence and rule out another vote.[34] In 2017 in Aberdeen, again outside the SNP conference, SIU organised an advertising van with the message 'Referendumb' that was unveiled to awaiting press as SNP members gathered for the conference.[35] A billboard campaign was launched again in 2021 in the run up to the 2021 Scottish Parliament election.[36]

In September 2018, SIU launched a 'Yawn' campaign, using newspaper advertisements. This was a campaign aimed at people who are 'tired' of the constant constitutional debate; "SNP politicians are still campaigning for an independence referendum that Scotland does not want. Tired of this?" The campaign gained additional media attention when a Police Scotland Twitter account tweeted in apparent support of the campaign, before deleting their tweet.[37]
