The BBC is not reflecting the views of its audience on immigration and asylum, a former top executive said.

Ex-editorial director Roger Mosey said the broadcaster suffers from ‘dysfunctional’ government and had succumbed to a ‘liberal group-think’ attitude.

Mr Mosey, once head of the corporation’s television news, claimed the Ten O’Clock News had been ‘sanitised’ and was ignoring white communities’ grievances.

He also mocked a BBC leaflet in which it said its target radio listeners were ‘Dave and Sue’ who had friends from many different ethnic backgrounds.

In his memoirs published in the Times, Mr Mosey said: ‘It must have been something of a shock to the writers of this leaflet when many real-life Daves and Sues went off and joined Ukip.’

The 57-year-old, now Master of Selwyn College, Cambridge, was once the de facto deputy to director general Tony Hall.

The BBC has been under increasing pressure about its alleged bias following its General Election coverage. Mr Mosey also criticised the BBC Trust, an internal body which monitors bias at the broadcaster, calling them a ‘shadowy force’ facing an ‘existential crisis’.

His other revelations include how BBC Trust figures considered offering a £1million salary to the director general – seven times that earned by the Prime Minister – due to ‘salary inflation’. Lord Hall earns £450,000.

At the height of the Jimmy Savile crisis, Mr Mosey said Newsnight was almost taken off air after it emerged the programme had shelved its own investigation into the former BBC star.

Mr Mosey said he remains a huge supporter of the corporation, but is uncomfortable about its 70 per cent share of television and radio news.

He believes the BBC must reflect the ‘age of austerity’, but fears its management is ill-equipped to cope with ‘a sky full of black clouds’.

Writing about the Savile controversy, Mr Mosey said: ‘When the stress tests have been at their most extreme, the corporation has tended to fracture rather than unite.’

The response by BBC chiefs to initial investigations into Savile were ‘an enormous cock-up in which there was miscommunication and misunderstanding’, he said.

Mr Mosey added that Lord Patten of Barnes, then BBC Trust chairman, ‘intensified the crisis’, placing an ‘indefensible strain’ on individuals.
