Valerie Trierweiler to sue over new biography

French first lady Valerie Trierweiler plans to sue the authors of the latest book about her because it spreads malicious rumours, her lawyer said Wednesday. Trierweiler, a 47-year-old journalist and partner of President Francois Hollande, is suing the authors of "La Frondeuse" (The Rebel) -- a biography due to be published on Thursday, for breach of privacy, lawyer Frederique Giffard told AFP. The book is the latest in a string of works on Trierweiler that have appeared since the Socialist Hollande was elected in May. They focus on her alleged feud with the president's ex-partner Segolene Royal, who is the mother of his four children.
