An interesting spat between the Labour Party and the BBC:
Labour Party Formally Complains To BBC Over Stephen Doughty's Live On-Air Resignation In Jeremy Corbyn's Reshuffle; BBC Rejects 'Orchestrated' Charge
I find the BBC's official denials disingenuous. The minister may have already decided to resign, but such a decision is not the same thing as a declaration. The BBC were not merely getting a scoop on the decision, they were staging the actual resignation and controlling the timing, enabling Cameron to use it to try to score points against Corbyn at Prime Minister's Questions immediately after the programme ...

It seems entirely possible that, thanks to BBC News, the Conservative leader could have known about the resignation before the Labour Leader,
to whom the resignation was supposed to be tendered, did. I think that is stepping quite clearly and quite deliberately over the line between neutral reporting and political interference.
