The EU says it is launching "formal enforcement proceedings" against the social media platform.

The European Union has formally announced it suspects X, previously known as Twitter, of breaching its rules in areas including countering illegal content and disinformation.

Digital commissioner Thierry Breton set out the alleged infringements in a post on the social media platform.

He said X, which is owned by Elon Musk, was also suspected of breaching its obligations on transparency.
