Parliament’s TikTok account has been closed after MPs raised fears about the social media firm's Chinese links.
Use of the popular app, owned by a Chinese parent company, had been an attempt to engage youngsters in Westminster politics.
But relations between Parliament and Beijing have been severely strained after seven MPs and peers were sanctioned by the Chinese state.
A spokesman said: "Based on Member feedback, we are closing the pilot UK Parliament TikTok account earlier than we had planned.
"The account was a pilot initiative while we tested the platform as a way of reaching younger audiences with relevant content about Parliament."
Welcoming the decision, former Tory leader Sir Iain Duncan Smith said: "We are pleased that Parliament, immediately they were told, understood there was a problem and shut it down.
"It's important for others to look at that now and we need to start talking to people about not using TikTok."
In a letter to the Speakers of the Commons and Lords, seen by the Politico website, a group of MPs who have been sanctioned by the Beijing government for speaking out about human rights abuses complained about the TikTok account.
"The prospect of Xi Jinping's government having access to personal data on our children's phones ought to be a cause for major concern," the letter said.
Theo Bertram, the app's vice president for government relations and public policy in Europe, told MPs in July "we have never been asked to provide TikTok user data to the Chinese government, nor would we if asked".
TikTok does not operate in China and the app's data is stored in the US and Singapore.
The firm has offered to meet any MP who wants to know more about the way users' data is handled.
A TikTok spokeswoman said: "While it is disappointing that Parliament will no longer be able to connect with the millions of people who use TikTok in the UK, we reiterate the offer to reassure those Members of Parliament who raised concerns and clarify any inaccuracies about our platform."
