BBC's Director General hits back at impartiality claim

Lord Hall, the director general of the BBC rejects the claim that its journalism is not impartial.

Ex BBC Trust Chairman Sir Michael Lyons, claimed that in the run up to the charter renewal, the BBC
' had bowed to political pressure with attacks on the leader of the Labour Party' .

Speaking to The World at One's Martha Kearney, Lord Hall said the BBC was often "quoted in surveys as being the UK's the most trusted source for news" and its journalists "test all sides of an argument".

Lord Hall also defended the distinctiveness of BBC content against criticisms that Bargain Hunt was in its 43rd season.
