Story summary

In October 2026, Sir Ken McCallum, head of MI5, warned that debating Russian interference in the 2016 Brexit referendum could empower Kremlin trolls. Speaking at MI5’s Thames House headquarters, he confirmed attempts by Russian media like RT and Sputnik to influence public opinion through biased reporting. Additionally, there were “trolls” using fake social media accounts on X (formerly Twitter) trying to sway the vote. However, McCallum emphasized that these efforts were not sophisticated or effective enough to impact the referendum’s outcome. He urged against giving undue attention to Russian actions, suggesting it might inadvertently benefit adversaries by creating unnecessary propaganda victories for them.
