Like it or not, the BBC is supposed to remain impartial, at the very least in their news broadcasts and news shows.
Piers Morgan can opine as much as he wants in the mail or ITV, just as O'Brien and Farage can opine as much as they want on LBC. It isn't the same situation.
The issue of course generally with impartiality is that it is very difficult to define and peoples' views on what is impartial is going to be based on their own biases. For the most part, someone who voted labour, SNP, tory, lib dems, greens are all going to have totally different views on what is impartial and what isn't.
The thing is, having watched her segment, I completely and utterly agree with every word. If it was me, I would have been even more scathing, on a wider range of topics, regarding a response that has been world beating its incompetence from the start.
Trying to be objective though, opinion does come into her segment, it isn't all fact. To me and you, it goes without saying. To others on the political spectrum, it isnt.
The problem of course is that our political discourse has reached the point where even facts can be and are disputed.
