Sir Richard Branson has been labelled a "tax exile" who is "literally laughing all the way to the bank" at the British public's expense by Jeremy Corbyn's campaign manager, while the Labour leader threatened the billionaire with the renationalisation of the railways.

Sam Tarry, the campaign director for Mr Corbyn's leadership campaign, launched his attack on Sir Richard, founder of the Virgin Group, after Virgin Trains released CCTV footage showing the Labour leader apparently walking past empty seats before creating a film on the floor of a train in which he claimed it was "ram-packed".
