The BBC is ‘evil’ and will take every opportunity it can to to prevent Jeremy Corbyn becoming prime minister, the Labour leader’s brother has said.

In an astonishing outburst, Piers Corbyn accused the corporation of a series of cover-ups to protect the Establishment - that included making attacks on his brother - but insisted Labour could still win a "reasonabl"’ majority.

Mr Corbyn, 70, who is two years older than his brother, also claimed the pollsters were getting it wrong by failing to detect "shy Corbynistas".
