The Daily Mail lost out in a newspaper battle for the serialisation of a biography of Simon Cowell over its "arrogant" belief that the author would not sell to Rupert Murdoch's The Sun, it has emerged.
Bower's agent is understood to have offered the biography to The Sun and the Daily Mail, in the hope of securing the biggest possible price.
According to The Guardian, the Daily Mail's owner Associated Newspapers offered considerably less than The Sun. A source close to Bower's agent said that the publisher was "too arrogant" and believed that the author would "not sell it to the Sun because of the Murdoch connection".
As Cowell's X Factor USA airs on the News Corporation-owned Fox in the US, the Daily Mail is understood to have wrongly thought that a Murdoch paper would not publish material critical of the star.
A source told The Guardian that the author's camp initially wanted £200,000 for newspaper syndication ahead of the book's release this weekend, but eventually settled for "above" £75,000 from The Sun. The deal is thought to be six figures.
In a curious twist, former News of the World journalists claim to have discovered Cowell's short relationship with Minogue a few years ago, but the story was reportedly dropped after Cowell phoned Rebekah Brooks, the former chief executive of the paper's owner News International.
News International owns The Sun and the News of the World, the Sunday tabloid that was shut down in July 2011 after a series of allegations of phone hacking of high-profile public figures. Brooks quit News International later in the year.
Sweet Revenge is not an official biography of Cowell, but Bower is understood to have spent around 200 hours with the multi-millionaire.
The Guardian reports that there "was no quote approval, but Cowell did give permission for some people to speak to Bower, while other associates were asked not to".
The author is understood to have challenged Cowell over the Minogue affair on "four occasions" before he confirmed it had happened.
