A French court on Friday upheld a ban against a kiss-and-tell book written by a former mistress of Cameroon star Samuel Eto'o. The Paris High Court originally banned publication of the book, entitled 'Revenge Porn - Football, sex, money: the testimony of Samuel Eto'o's ex', last week, leading to lawyers for Nathalie Koah to appeal. But the Paris High Court's appeal division confirmed the original ban. Olivier Prado, the lawyer for publishers Editions du Moment, described the verdict as "a huge setback for liberty of expression and publication".
