Meta Platforms will end political, election and social issue advertising on its platform in the EU in early October, blaming legal uncertainties due to new EU rules on political advertising, the U.S.

Facebook and Instagram owner Meta said Friday that it will stop all political advertising in the European Union by October, blaming legal uncertainty over new rules designed to increase transparency in election campaigns.

Meta said political advertising would end in October, citing a forthcoming E.U. regulation that it said presented “unworkable requirements.”
