as a 'fat, troughing scum' is your idea of a well-made argument or a clever way to debunk myths, then the standard of our national debate really has fallen into disrepair". Campbell stated that the comments were reported out of context and were an isolated instance, and that he would apologise when Johnstone apologised for his personal attack on pro-independence donors Chris and Colin Weir which had provoked Campbell's remarks. Defamation lawsuit In March 2017, Kezia Dugdale used her Daily Record column to allege that Campbell had posted "homophobic tweets" involving the Conservative MSP Oliver Mundell and his father, MP David Mundell, who is gay. Campbell's tweet read "Oliver Mundell is the sort of public speaker that makes you wish his dad had embraced his homosexuality sooner". Campbell sued her for defamation, seeking damages of £25,000.

In his judgement, the Sheriff said he did not believe Campbell had suffered any hardship and had he been minded to award any damages the sum would have been £100 rather than the £25,000 sought by Campbell. Campbell unsuccessfully appealed in May 2020, although the three appeal court judges again found that Dugdale's comments had been "a straightforward direct defamatory statement" and that "It is not now disputed that the article was, in its reference to the pursuer as homophobic, defamatory". The appeal court also increased the notional value of damages by 50 times, from £100 to £5000, but nevertheless upheld Dugdale's "fair comment" defence. Reflecting on Campbell's comment and the court case in July 2021, David Mundell told the House of Commons: "I regard that as a victory, at least in Scotland, for those willing to stand up against homophobia, and I remain particularly grateful to Kez for her support. Twitter ban In December 2019, Wings Over Scotland's Twitter account was permanently suspended for alleged violations of the platform's rules against hateful conduct. In May 2020, Twitter permanently suspended two more of Campbell's Twitter accounts, including his personal one, for alleged violations of the platform's rules. In response, Campbell denied having broken any of Twitter's rules and accused Twitter of ideologically-motivated
