The lead item on Newsnight last night was Castro's departure. I was one of the studio guests debating the issue. The others were a Cuban-American activist, Frank Calzone; a pro-Castro Cuban journalist, Pedro Perez-Sarduy; and, inevitably, George Galloway. You can watch the programme on the Newsnight website till tomorrow's edition replaces it, though I'm not sure I'd recommend it. At one point Galloway advanced an unusually labyrinthine "Bush-Hitler" analogy, and I regret that my sniggering off-camera was clearly caught by the microphone. In the circumstances, I asked Mr Galloway not to make me laugh as he was the one with a record as long as my arm of justifying autocracy across the globe.
