Veteran BBC presenter James Naughtie lost patience with two guests appearing on his Radio 4 show this morning, demanding they both "shut up, just for a second".
The Today presenter intervened as Times columnist Jenni Russell and Sunny Hundal, who runs the Liberal Conspiracy site, got in a spat over Ed Miliband's performance record.
Things got heated as the pair discussed the Labour Leader, who returned to work after his summer holiday with a splat today – getting pelted with eggs by a protester in Walworth, London.
The Radio 4 presenter became increasingly frustrated as the pair continually talked over each other, visibly becoming irate.
After they ignored the presenter's repeated requests to "hang on a minute," Mr Naughtie finally snapped and sniped: "Look, will you two shut up, just for a second, we are trying to have a civilised discussion here."
The firmly-worded interruption worked however, and the two guests quickly piped down and looked on sheepishly before politely finishing their discussion.
