Ofcom has opened an investigation into Telegram over issues of child sexual abuse material shared on the app.
The regulator said it had reviewed evidence and decided to examine whether Telegram has failed, or is failing, to meet its legal duties on illegal content under the Online Safety Act 2023.
The case adds to complaints on online platforms operating in the United Kingdom, where authorities want stronger protection for children from harm online.
Ofcom said the law requires platforms to reduce risks linked to illegal material and act where such content appears. It added that companies must be able to show they are meeting those duties.
Telegram rejected the allegations.
The company said it “categorically” denied Ofcom’s accusations. It added that since 2018 it had “virtually eliminated” the public spread of child sexual abuse material through detection algorithms.
Telegram also said, “We are surprised by this investigation and concerned that it may be part of a broader attack on online platforms that defend freedom of speech and the right to privacy.”
The regulator also opened separate investigations into Teen Chat and Chat Avenue. It said it was unconvinced that both platforms were doing enough to protect children from grooming risks.
Suzanne Cater, Ofcom’s director of Enforcement, said, “These firms must do more to protect children, or face serious consequences under the Online Safety Act.”
The inquiry comes as Keir Starmer’s government pushes for tighter online safeguards, especially for younger users.
Telegram has faced similar cases elsewhere. In February, Australia’s online safety regulator fined the company after delays in answering questions about measures against child abuse and violent extremist material.
The UK law is considered one of the strictest internet safety frameworks in the world. It places direct responsibility on platforms to tackle illegal and harmful content or risk enforcement action.
