TikTok has been banned from Government devices - but ministers and officials will still be able to use the app on their personal phones.
Cabinet Office minister Oliver Dowden announced the ban with "immediate effect" on Thursday. He said the ban, criticised by TikTok, was "a prudent and proportionate step following advice from our cyber security experts".
The ban, which is not being extended to members of the public, was being imposed over risks around how sensitive information can be accessed by TikTok. "The security of sensitive Government information must come first, so today we are banning this app on Government devices. The use of other data-extracting apps will be kept under review," the minister said.
