As for question time I agree the BBC do treat it as entertainment, to a point, and try to put up politicians with a knack for self publicity, those who are controversial and attract an audience,and a bit of glamour (of sorts) , how else did Caroline Flint top the charts?

Caroline Flint, objecting to the concept of being treated as female window dressing. The photograph is from the Guardian website, which helpfully includes the details Caroline Flint wears: red dress, £180, Karen Millen, 0870 160 1830; shoes, £70, Topshop.
The political bias though is firmly towards globalism and anti Britain, especially working class Brits who have been the target of BBC denigration since as long as television has existed (and maybe before).
