The EU asked the companies to provide more information by February 9 on measures they have taken to give researchers access to data that could be relevant to the upcoming EU and national elections as well as countering illegal content and goods sold online.

The DSA came into force in November last year and requires very large online platforms and search engines to do more to tackle illegal content and risks to public security.

The Commission opened its first probe under the DSA in December 2023 into social media company X over suspected breaches of its obligations.
