Kuenssberg has form in this regard. Her coverage of the Scottish Independence vote is infamous North of the border, the BBC trust actually ruled against her coverage of Corbyn and she is clearly joined at the hip to Johnson.
I have no idea if her bias is conscious or not but it is clear her independence is compromised which, as she is political editor of the BBC, is an issue. If she wrote for the Spectator then fair enough.
If the BBC is seen as the mouth piece of the Government (or of a particular political persuasion) , which it is by many in Scotland since 2014, that is a terrible shame in my mind. I do genuinely believe the BBC, in general, tries to be impartial, often resulting in laughable equating of argument positions in the interest of balance.Of course, we all have our own convictions and that influence is very hard to eliminate utterly, but LK has either lost her capacity for self reflection or has actively crossed the line to a partizan position. It is very disheartening.
