Elon Musk's X is being used as a key 'weapon of mass manipulation' for Russian disinformation, the EU says, and warns it is 'watching' the social network

• An EU report found X has the highest proportion of Russian disinformation of any major social network.
• A senior official warned that the site "has to comply with hard law" over disinformation.
• X said that it disagreed with the "overall framing" of the data published in the EU's report.

The EU has warned that X, the social media company owned by Elon Musk, must clamp down on disinformation, after a study found that Russian propaganda was proliferating on the site.
