John Humphrys used the big interview slot on Radio 4's Today programme to deliver a masterclass in forensically dissecting a dissembling politician in the form of Nick Clegg. He was not allowed to get away with the trite, prepared lines about the deficit being worse than expected or the budget being progressive. He even tried to dismiss the report from the highly-respected and avowedly independent Institute for Fiscal Studies, which defines the budget programme as regressive. Every time, Humphrys challenged assertions with awkward facts and every time, Clegg floundered and flailed as the interview failed to follow the script that he expected.
It is well worth listening to it on the Today website, to hear a master interviewer at work. If you have the stomach to listen to the sound of a man drowning in his own spin.
