Watchdog issues warning over misinformation after trouble that flared following killing of three girls on Merseyside

Social media algorithms must be adjusted to prevent misinformation from spreading, the chief executive of Ofcom has warned, responding to the rioting that broke out after the killing of three girls in Southport this summer.

Misinformation about the Southport killings proliferated despite tech firms and social media platforms' uneven" attempts to stop it, wrote the Ofcom chief executive, Melanie Dawes, in a letter to the secretary of state for science, innovation and technology, Peter Kyle.
