Watson also criticised British news sites for running the Christchurch attacker’s footage and manifesto. “It’s deeply concerning and irresponsible that mainstream news sites are giving a platform to the hateful extremist violence that has devastated so many lives, particularly after the New Zealand authorities have asked for the footage not to be shared,” he said.

Mail Online’s main story on the terrorist attack featured an edited-version of the terrorist’s video, showing him approaching one of the mosques and drawing his weapon. The pop-up video also followed the reader down the page.

In another story that focused on the terrorist’s manifesto, the website uploaded a PDF of the document in full, allowing readers to read and download it. The embed was later removed after BuzzFeed News approached the publication for comment.
