I've just read some official election guidance for government workers. Looks like somebody, somewhere also thought about what "purdah" might say about us. They say that it is "now commonly known as 'the sensitive period'."
Commonly? And "sensitive period" sounds like something made up by advertisers to sell a rancid yogurt drink, or painkillers maybe.
Still nowhere near the beaten track.
Postscript 13/04/10. The Organisation has opted to call it "the pre-election period". I'm proud of them.
