Labour has promised to hold an inquiry into “fake news” and take action against the Duopoly’s “monopolistic hold” on the digital advertising market if Jeremy Corbyn is voted in to power next month.

The party’s manifesto, published this morning, said it plans to consult media sector workers and trade unions before establishing an inquiry into “’fake news’ undermining trust in media, democracy and public debate”.

The inquiry would also look into the “legal right of public interest defence for journalists”, the manifesto states.
