"If the material can be used for a personal book by which the ex-Minister profits, why shouldn't they be public?"The material used in the profitable personal book was allowed to be published, apparently. The unallowed material was not made public, and so was not profited from. Until the Telegraph published it (I assume profitably).The co-writer also profited from the published book, but then discovered "public interest". Belatedly?
