Asked about the new TikTok account, the prime minister's official spokesman told reporters: "We've always said that we keep the way in which we communicate with the public under review to make sure that we are reaching people with information on government services and how we're improving the lives of working people, and we always keep social media practices under review.".
"It was always the case that there were specific exemptions for the use of TikTok on government devices where required for work purposes, and those exemptions are only granted by security teams on a case-by-case basis and with security mitigations put in place.
Number 10 has indicated a security exemption has been made for the account, insisting the ban on TikTok on official government devices - which began in 2023 - remains in place.
He added: "In line with security advice, we've been permitted the use of a UK government TikTok account... under specific circumstances.".
TikTok remains banned on all UK government phones - despite ministers launching an official account, Downing Street has said.
