Montana has become the first US state to pass legislation banning TikTok on personal devices.

TikTok, which is owned by Chinese company ByteDance, has been accused of posing a national security risk through data gathered from users.

If signed into law by Governor Greg Gianforte, the ban could come into effect in January.

The company has suggested that it would take legal action to fight the Montana bill.

The bill, known as SB 419, passed by a vote of 54 to 43. It cites a number of concerns about TikTok, including alleged surveillance from the Chinese government.

Violations of the bill could carry a penalty of up to $10,000 (£8,000), which would be enforced by Montana’s Department of Justice. The penalties apply to companies, rather than individual users.

Mr Gianforte, a Republican who previously banned the app on the devices of government employees, is expected to sign it.
