Billionaire Elon Musk has offered $43bn to personally acquire Twitter. More controversially, he has offered $86bn to buy two Twitters.
"It's good to have a spare", explained Mr Musk, "I kept my old phone when I upgraded recently, just in case something happens. If I accidentally dropped Twitter or, more likely, accidentally got involved in a ruinous libel suit, then I'd like to have another one I could pull out of the drawer."
