Did Russia interfere with the Brexit referendum?

LONDON, 12 OCTOBER 2026 —

UK Prime Minister Andy Burnham confirms Russia interfered in Brexit referendum, warns of broader European threat

Burnham’s admission follows years of speculation and limited official recognition, with the UK government previously downplaying the scale of Russian meddling. His comments coincide with warnings from intelligence agencies about ongoing Russian efforts to destabilise democratic institutions, and come as he seeks to strengthen transatlantic cooperation to counter such threats.

The revelation has sparked debate over whether the UK has adequately addressed the risks posed by foreign disinformation, particularly in light of similar concerns in Germany and France.

Burnham told the podcast that upon assuming office in July, he had asked his advisers whether Russia had interfered in the Brexit referendum. “I’ve had the clear answer that yes, there was,” he said. “These things are important now to put clearly on the record.” He added that such interference was not isolated to the UK, but part of a broader pattern of Russian disinformation targeting European democracies.

“Countries across Europe are facing the same threat,” he stated, urging voters in Germany and France to recognise that “some of this politics is instigated via our enemies, namely Russia.”

The prime minister’s comments align with findings from the UK’s Intelligence and Security Committee (ISC), which in 2020 concluded that the government had failed to fully assess the impact of Russian state-run media and “troll” accounts on the EU referendum. The ISC report highlighted gaps in monitoring and response, suggesting that the UK’s democratic resilience was compromised by inadequate safeguards.

Burnham’s admission now puts pressure on the Foreign Office to clarify the extent of Russian involvement and the measures taken to counter it.

Foreign Office Minister Stephen Doughty, however, has publicly disputed Burnham’s framing. In separate interviews with Sky News and the BBC, Doughty acknowledged that Russia had attempted to interfere in UK democratic processes but insisted that such efforts had not succeeded in influencing the Brexit outcome. “Russia clearly has attempted to interfere on a number of our democratic processes,” Doughty said, citing Moscow’s spending of £1.5 billion ($1.9 billion) in 2016 on disinformation and propaganda.

However, he declined to provide specific evidence of interference during the referendum, stating he would not “get into specifics.”

Doughty also rejected suggestions that Burnham’s remarks were motivated by political calculations, such as advancing a pro-EU agenda. “The prime minister was making a broader point about Russian attempts to destabilise British democracy,” he said. Yet Burnham’s insistence that the issue be “put clearly on the record” signals a deliberate effort to shift the narrative, particularly as he seeks to address what he describes as a “decade of drift and division” in UK politics.

“We have had a decade of drift and division that has caused more harm than good,” Burnham said. “In my view, we are a more fractious country than we were. We have a weaker sense of direction. And these are all the things I’m trying to fix as prime minister.”

The prime minister’s comments also extend to Germany, where he met with Chancellor Friedrich Merz last week to discuss alleged ties between Russia and the far-right Alternative for Germany (AfD) party. Burnham claimed that Merz had informed him that the AfD was “clearly linked to Russia, funded I believe,” and that Russian disinformation was actively influencing German politics. “There is certainly misinformation, disinformation that is emanating from Russia into German politics,” Burnham said.

He called for greater cooperation between the UK and Germany to counter these threats, framing the issue as a shared European challenge.

The UK’s intelligence agencies have long warned of Russia’s use of hybrid warfare tactics, including disinformation campaigns, cyberattacks, and support for extremist groups to undermine democratic processes. Burnham’s acknowledgment of Russian interference in the Brexit referendum marks the first time a UK prime minister has publicly confirmed such involvement, though the scale and methods remain largely unspecified.

The lack of transparency has led critics to argue that the UK has been slow to address the risks, particularly compared to other Western nations.

Analysts note that Burnham’s timing is significant, coming as the UK grapples with ongoing political instability and a divided public opinion on Brexit. His remarks could influence public perception of the referendum’s legitimacy and may prompt calls for greater scrutiny of foreign interference in future elections.

The Foreign Office has not yet responded to Burnham’s claims, but the dispute underscores the broader debate over how the UK should respond to foreign meddling in its democratic processes.

As Burnham pushes for stronger measures to counter disinformation, the issue has gained urgency in Europe, where similar concerns have emerged in France, Germany, and beyond. For now, the admission of Russian interference in the Brexit referendum stands as a stark reminder of the vulnerabilities in democratic systems and the persistent challenge posed by state-sponsored disinformation.
