This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Nigel Farage is repeatedly implicated in the spread of misleading or demonstrably false claims tied to the Brexit campaign; academic analyses and investigative reporting single out his social-media activity, repeated high-profile slogans such as the "£350 million a week" NHS claim, and coordinated targeting tactics as the most prominent examples [1] [2] [3]. Farage and allies have frequently denied wrongdoing or distanced themselves from specific pledges, while parliamentary and media inquiries have documented how Leave campaigns used targeted messaging and data-driven placement of Farage at campaign hotspots [4] [5].
1. The "£350 million a week" money-for-NHS slogan: a shorthand that misled
One of the most enduring and cited instances connected to Farage is the Leave-side claim that the UK sent £350 million a week to the EU and that this could instead fund the NHS; researchers and fact-checkers have repeatedly treated that figure as misleading because it doubled net contributions and did not account for rebates or EU spending back to the UK [1] [3]. The slogan became politically toxic enough that some Leave figures later disowned it as a campaign mistake, a move reported by outlets tracking post-referendum backtracking [4] [3].
2. Social media performance and tweet-level misinformation during the campaign
Academic work that analysed more than 1,400 tweets from Britain’s main opinion leaders during the referendum found that Farage — along with Boris Johnson — shared multiple misleading arguments on Twitter, making him a notable "human component" in the circulation of false or exaggerated claims around Brexit [1] [2]. The studies screened leaders’ posts between February and June 2016 and concluded Farage’s Twitter output included a higher incidence of misleading claims than some peers, although the research focuses on general patterns rather than an exhaustive catalogue of every falsehood [2] [1].
3. Targeting voters and placement: Farage as a data-driven weapon in Leave’s toolkit
Parliamentary inquiries into fake news and referendum campaigning published testimony indicating that campaign operatives used actuaries and data to identify prime locations and intentionally sent Farage to those areas, an approach that critics argue amplified targeted misleading messaging by leveraging his profile [5]. The DCMS excerpts and committee material made clear that Farage was deployed strategically by Leave-affiliated groups, raising questions about how high-profile figures can be used to magnify tailored disinformation strategies [5].
4. Post-vote distancing and the politics of accountability
After the referendum result, several senior Leave figures, and at times Farage himself through various statements reported in the press, distanced themselves from specific pledges or claimed they were mistaken, a pattern chronicled in contemporary reporting that complicates any straightforward account of culpability [4] [3]. Media outlets documented both the original claims and later disavowals, underscoring the difficulty of retroactive accountability when slogans have already entered public discourse [4].
5. Overlaps with foreign influence concerns and continuing scrutiny
Separate reporting and prosecutions have since examined whether figures in Farage’s political orbit took lines or talking points from foreign actors; prosecutors allege that several MEPs in Farage’s bloc followed scripts given to colleagues who were in contact with an alleged Russian asset, and investigators have probed links between Reform/UKIP figures and foreign interference more broadly — developments that feed public concern about how misinformation and external influence may have intersected [6] [7]. These reports do not by themselves prove that Farage personally coordinated with foreign agents, and some of the cited materials call for further inquiry [6] [7].
Conclusion: denials, limits of public record, and where the evidence points
Farage and his campaigns have denied that they deliberately shared misinformation in several contemporary accounts (for example, on non-Brexit topics such as WHO treaties) and have pushed back against allegations of foreign links, framing some coverage as "fake news" [8] [9]. The most substantiated claims in the public record, however, are: repeated misleading slogans like the £350m NHS figure, the academic finding that Farage was a regular source of misleading social-media claims during the campaign, and parliamentary evidence that he was deployed strategically to prime audiences — all of which together make the cited examples the most prominent instances tying Farage to Brexit-related misinformation in existing reporting [1] [2] [5] [3]. Where the sources are silent — for instance, on Farage’s personal intent or every causal pathway from his posts to voter decisions — reporting does not provide definitive answers and further investigation would be needed [1] [2] [6].
