The billionaire businessman Elon Musk has backed out of a $44bn deal to buy social media site Twitter. Mr Musk said he'd pulled out because Twitter failed to provide sufficient information on the number of spam and fake accounts. But the world's richest man faces a $1bn break-up fee and possible lawsuit by opting out. Shares in Twitter fell by 7% in extended trading after Mr Musk's announcement.
