His own reasons being the press and their underhand illegal activities. Not the money. He refused it.
I can't believe how dismissive some posters who just want to score one up on Harry are at these underhand illegal activities. If there wasn't a case to be heard, there wouldn't be one.
But apparently... we shouldn't be aghast at illegal phone hacking, illegal bugging of houses and cars achieved by breaking and entering, paying off police to dish dirt, employing PIs to spy, illegal accessing of medical and financial records by bribery.
Nothing to see here folks.
