The wonders of live television. As some of you may have heard, I took a turn presenting the Andrew Marr show yesterday. I was hoping to create some news stories for the Monday papers, as Andrew often does. And I did. But not in quite the way I'd hoped.
With four wide-ranging interviews to prepare for, I had read up on everything from the UK-US extradition treaty to Maureen Lipman's stage career. Little did I realise that my greatest challenge would be General Sir Mike Jackson's mobile phone. You can watch what happened below.
It is somewhat disconcerting that the former head of the British army doesn't know how to switch off his phone. But clearly, the moment had great comic potential. If only we hadn't been in the middle of discussing Afghanistan.
