TikTok will be banned on Government phones, ministers are expected to announce after security concerns were raised about use of the Chinese-owned app.
Cabinet Office minister Oliver Dowden will announce details in the Commons on Thursday, it is understood.
Prime Minister Rishi Sunak has been under pressure from senior MPs to follow the US and EU in banning the social media app from government devices.
TikTok said bans have been based on “misplaced fears and seemingly driven by wider geopolitics”, saying it would be “disappointed by such a move” in the UK.
A Scottish Government spokesperson said: “Regulatory responsibility for social media lies with the UK Government.
“Devices managed by the Scottish Government are configured in line with best practice from the National Cyber Security Centre, which helps us to manage any risk associated with the use of third-party applications.
“Following this announcement, officials are liaising with the Cabinet Office as we consider the need for further action on this issue.”
