General opinion was that he was trying to appear a cool dude
I watched all of it, I didn't like the face to face clips with carefully selected members of the public. The Beeb slipped up though, as the imman they featured has been"Twitting" anti jewish posts and I believe he has been given the boot.
I also thought Emily Maitlis was just awful ! she interrupted all the time and her snappy comments were aimed mostly at Boris Johnson. It wasn't a 'debate' and if you didn't watch it, you missed nothing !
