The media tycoon Richard Desmond today starts a battle against investigative biographer, Tom Bower over allegations he made in his bio of Desmond, provisionally entitled Rough Trader.

Bower is a biographer who targets 'heavy hitters' and has written bios on Branson, Maxwell, Conrad Black, Al Fayed, Geoff Robinson and Gordon Brown.

Bower apparently has no plans to write a bio on Rupert Murdoch. This has nothing whatsoever to do with the fact that the last Bower bio was published by Harper Collins, part of Rupert Murdoch's News Corporation.
