The public is to challenge Tony Blair on the country’s key political issues during a gloves-off televised debate.

This is what my long conversation last week alluded to: I was asked to take part in this programme. Unfortunately (or, perhaps, fortunately for the PM), things didn’t work out, and so I don’t feature. But it should be worth watching nonetheless – you never know, it might include Mr Blair’s Iraq homologue of Mrs Thatcher’s “Nationwide” moment about the sinking of the Belgrano. Five, 7pm.
