Mark Zuckerberg to sell $2bn in Facebook shares

Facebook and Mark Zuckerberg, the social network's billionaire founder, are selling another $4bn (£2.5bn) worth of shares in the first such move since the firm floated last year.

More than 41 million of the shares belong to Mr Zuckerberg, who will use the $2.3bn raised to pay a tax bill he's incurred for exercising an option to buy 60 million more shares at a fraction of their market price. The taxman views the paper profit he will make on them as income and taxes it accordingly.
