When Andrew Marr interviews politicians, I often turn the sound off and watch their body language. You can tell a lot from that.
An exception yesterday was his interview with David Milliband who was speaking in his role as chief executive of the International Rescue Committee and very depressing it was. He has coined the term 'the age of impunity'.
However, he was also asked his opinion on Brexit which, as you may imagine, was entirely negative. He called it a 'wrecking ball' and supported the call for a second referendum.
I recommend that you find the Andrew Marr Show on I-Player - the interview is near the start, just after the review of the newspapers. Some of you may agree that this is the man who should have been our prime minister.
