Hats off, again, to the team at The Telegraph. Its coverage of the MP expenses scandal boosted summer circulation figures for the newspaper itself, now they've come out with a book telling the whole incredible story of the exposé.

No Expenses Spared is generating more wall-to-wall coverage for the publisher, and surely it will become a bestseller. The perfect stocking filler for those who like a little apoplexy with their light reading, perhaps.

Published via Random House imprint Bantam Press, it should be music to the ears of CPI too, as I imagine they will have printed it.

The Telegraph's own news story on the book launch talks of "taking you inside The Stationery Office" and pinpoints the mole as a worker there. Will be fascinating to see how TSO reacts to this given its previous vehemence on the topic. When the BBC story about the book and the source of the leak was first published on its website late last night, it included a reference to HMSO, but I see that has now been removed.

One a wider note, this whole sorry affair is a cautionary tale for any business involved in handling sensitive information, and there will be lots of printers who fall into that category.
