Facebook has announced new rules on political advertising in the UK; you'll need to prove your identity and location, and each ad will carry a message saying who paid for it. Sam Jeffers is co-founder of Who Targets Me, an organisation that tracks political ads.

James Harding, the former Director of BBC News, explains Tortoise, his "slow news" venture which promises "open journalism” and a “different kind of newsroom”.

And Claire Beale, global editor-in-chief of Campaign, on her magazine's 50th anniversary and new trends in advertising.
