London Mayor Sadiq Khan has issued a stark warning about a "dark blizzard of disinformation" sweeping across social media platforms, accusing tech companies of enabling organized networks to profit from societal division.
Speaking at the Cambridge Disinformation Summit, Khan presented new City Hall research revealing a dramatic surge in coordinated online campaigns portraying London as a city in dangerous decline. The analysis found that between March 2024 and March 2026, narratives framing the capital as a "fallen city" increased by 150-200%, while migration-related discussions referencing London skyrocketed by over 350%.
"As extremists erode trust in our city and its institutions, it gets easier and easier for them to twist online anger into offline violence," Khan warned.
The report identified coordinated efforts by UK-based extreme right-wing groups, accounts aligned with Russian or Chinese state interests, and US-related political movements amplifying these claims. One network based in Vietnam used AI-generated imagery and impersonated local media outlets to spread emotive content to more than one million followers.
Encrypted messaging apps like Telegram were highlighted as key channels where disinformation originates before spreading to mainstream platforms. The mayor pointed to real-world consequences, citing the case of a retiree who blew up a Ulez camera with explosives after being exposed to conspiracy theories in social media groups.
Despite these alarming trends, Khan noted that London's per capita homicide rate has actually fallen to its lowest level on record. He emphasized he wasn't seeking to silence legitimate criticism, stating, "I haven't come here today to ask anyone to take down content which criticises me," but argued that the "outrage economy is eating away at the basic bonds of trust that hold our societies together."
In response to the crisis, Khan has sent letters to major social media platforms including TikTok, Meta, Google, and X, demanding greater transparency and an end to "opaque algorithms designed to maximise engagement at any cost." He called for tech companies to provide "vetted independent researchers" with access to their data for better monitoring of coordinated disinformation.
Platform responses varied:
- TikTok noted it has "specialized teams to detect and remove coordinated inauthentic behavior"
- Meta said it was "constantly working to disrupt" such networks and had removed over 200 globally
- Telegram stated it supports "peaceful free speech" and removes calls to violence when discovered
The mayor also urged the UK government to take a "much tougher approach" by creating a new central body to protect democracy and empowering regulators like Ofcom with stronger enforcement capabilities.
Khan concluded with a sobering prediction: "In a few years' time, I think we'll look back on London as the canary in the coalmine. But I hope we'll also see it as the place where the fightback began."
