Delve Special

Delve Special (Radio 4, Fridays and Saturdays) is another series much admired first time round, a spot-on satire on investigative reporting. This time, the comedy is standing up well, though again there's a chill in the laughter. For the Delve Special programmes are only too near the truth; and is it really risible to hear our defence experts, in the first programme, so accurately made out as fools?

Delve (Radio 4, Fridays), a four-part series about the Shifton Scandal, is a well-observed satire on investigative reporting, from Checkpoint to almost any of those admirably worthy local radio programmes about their own local planning scandal. Indeed, a visitor to my kitchen had just about set up a protest committee of her own before she realised that the new London Airport at Shifton was (on this occasion) an invention.
