[quote borntobequiet] I had BBC News channel on earlier and the presenter was so openly sceptical about Russian claims I thought he'd get done for lack of impartiality. He couldn't have made his opinion more plain if he'd worn a seaside hat emblazoned "Putin is a lying arsehole".
Was it this, Perking? www.bbc.co.uk/iplayer/episode/p0bx9slf/ros-atkins-on-ros-atkins-on
Another very good BBC News programme for a wide and unbiased take is Dateline London

No, I've just looked it up and it was Context with Christian Fraser.

But Ros Atkins also has a fine unspoken air of, "Yeah, no one believes you." 
Fraser's guests yesterday included Jonathan Powell, the Northern Ireland negotiator, who now specialises in negotiations.
He talked about a concept called "mutually hurting stalemate": peace negotiations are only successful if both parties are in some discomfort from a stalemate and see something to gain from resolving the situation.
He said he doesn't see this in Ukraine at the moment, because although Ukraine is obviously hurting, Putin isn't particularly. Therefore Putin has nothing to gain from peace.
As I remember, the guests agreed that the negotiations were just window-dressing from Putin's point of view, but nonetheless the Ukrainians felt they had to keep turning up as they needed to feel they were exploring every avenue.
My own opinion is that it's also politically important for Zelensky's team to pursue peace through negotiations as well as militarily, otherwise they would undoubtedly be criticised for not doing so.
