European Union: Implemented Regulation on the transparency and targeting of political advertising including content moderation obligations

On 10 October 2025, the Regulation on the transparency and targeting of political advertising entered into force. The Regulation outlines transparency obligations concerning political advertising, including advertising displayed on online platforms, mobile applications, websites, games and other digital interfaces. In particular, the Regulation requires providers of political advertising services to label the content displayed on their platform as political advertising if they signed a contract with the sponsor and received remuneration. Furthermore, the providers of political advertising are required to establish a flagging mechanism to enable users to notify them of any advertisement that does not comply with the Regulation. Finally, the Regulation prohibits providers from displaying political advertising sponsored by third-country entities three months before an election or referendum.
