The BBC has a "cultural leaning to the left" and needs to work on its impartiality, a British cabinet minister says.
Justice Secretary Chris Grayling said the BBC did things that were not "right and proper" for a public broadcaster, saying the problems were not just confined to current affairs programs but also affected entertainment shows.
"I think there's still an inclination to cover issues in a way that is very much about the culture of a slightly left-leaning, metropolitan group of people who are disproportionately represented there," he said.
The BBC has come under fire from senior Conservatives over the way it has reported the government's benefits cuts and recently the corporation insisted that a description of an "incoherent" mayor of London which featured in an episode of Sherlock was not an attack on Boris Johnson.
In an interview with The House magazine Grayling said: "They've been on the wrong side, they've been unbalanced in the debate over the years about immigration, about Europe. And I think they've wised up to that.
"But there is still a cultural view within the BBC, not just within current affairs. To some extent it's less with current affairs than within general entertainment, the throwaway lines in a drama which still suggest that actually the BBC's got some way to go before it really, to my mind, fulfils the role it has to be a genuinely dispassionate public service broadcaster."
He added: "The BBC is a great institution and I wouldn't want to tear it up. But I think it's still got some work to do."
Grayling said: "I think the real problem for the BBC is not that there is an intentional bias at senior levels, not that it is institutionally biased against us. But it's that there is a cultural leaning towards the left.
"The people who work at the BBC have a particular viewpoint on life more often than not."
There were people at the corporation who "want to be impartial in the way they present issues" but there was a "cultural challenge which isn't easily solved".
Grayling said: "The BBC is generally very good, but there are moments when it really does things in ways that you think 'this is just not right and proper for a public broadcaster who's trying to present a dispassionate view on life'."
