I agree Liz. Marr was rude. Interrupting and at one stage telling the PM he was chuntering. He may well have been but it was impolite and no example to others especially younger people.. Like Boris J or not, he is PM, and is therefore entitled to respectful behaviour by members of the media. Funny that Marr didn't give Chukka Umunna and especially Baroness Chakrabarti the same treatment.
