How I keep Question Time audiences under control

Philadelphia is the city of brotherly love – or it’s supposed to be. William Penn, good Quaker that he was, wanted his city to be a place of religious and political tolerance; a haven for those who’d been persecuted for their beliefs. There are quotations inscribed on walls everywhere about the power of love, selflessness and charity. Given how vicious and divisive this presidential election is, the message seems lost on both parties. I flew out to Philly this week for a special Question Time episode, the first time the programme has been to the US since 2008. One of our panellists has had to pull out at the last minute, so the hunt is on to find a replacement. This is a usual problem for QT. I’m more worried about the studio audience, since they will be unfamiliar with the format. Will they speak up enough and get stuck in? Perhaps I should have other concerns.
