A systematic analysis of 20,000 posts from Donald Trump’s social media accounts has identified a consistent pattern of language that experts characterise as authoritarian, prompting concern among UK foreign policy specialists about the former president’s influence on democratic norms.
The study, conducted by researchers at the Center for the Analysis of Social Media at the University of Oxford, examined posts from Trump’s Truth Social account and his earlier Twitter feed between 2009 and 2023. The findings, published overnight, show a marked increase in rhetoric that dehumanises opponents, attacks independent institutions and undermines electoral integrity.
Professor Lucy Barnes, lead author of the report, said the language used by Trump mirrors tactics employed by autocratic leaders to consolidate power. “We observed a deliberate shift from conventional political discourse to a style that delegitimises dissent, frames opposition as unpatriotic, and positions the leader as the sole arbiter of truth,” she said.
The analysis coded each post for 12 indicators of authoritarian speech, including calls for loyalty, threats against critics, and claims of electoral fraud. The results show that after the 2016 election, Trump’s use of such language doubled, and by 2020, nearly half of his posts contained at least one authoritarian trope.
UK foreign policy experts have expressed alarm. Sir Andrew Wood, former British ambassador to Russia, said the findings echo the rhetoric used by Vladimir Putin in the early stages of his consolidation of power. “This is not merely about one politician. It reflects a broader trend where democratic safeguards are eroded through language that normalises autocracy,” he said.
The Foreign Office declined to comment directly, but a source indicated that Whitehall is monitoring the implications for transatlantic relations. “If a former US president openly questions the legitimacy of elections and attacks the press, it weakens the credibility of democratic institutions globally,” the source said.
Trump has long dismissed such analyses as biased. A spokesperson for his campaign said, “President Trump speaks directly to the American people, not the elites. He says what millions are thinking.”
The report comes amid mounting anxiety in European capitals about the resilience of democratic norms in the United States ahead of the 2024 election. Analysts warn that the impact of such rhetoric extends beyond America’s borders, emboldening populist movements in Europe and undermining Western unity on issues such as Nato funding and sanctions.
The study is published in the Journal of Democracy and has been peer-reviewed.
