LONDON, Nov 16 (Reuters) - Britain's Crown Prosecution Service (CPS) has authorised seven additional charges against Oscar-winning actor Kevin Spacey for a number of sexual assaults against one man between 2001 and 2004, it said on Wednesday.The new CPS charges include one of causing a person to engage in sexual activity without consent and others of indecent and sexual assault.Spacey, 63, was previously accused of five offences in Britain - four counts of sexual assault by touching, and a more serious charge of causing a person to engage in penetrative sexual activity without consent.His lawyer had said in June Spacey had "strenuously" denied those allegations of sex offences.In the United States, Spacey last month defeated a sexual abuse case against him after jurors in a Manhattan civil trial found his accuser did not prove his claim that Spacey made an unwanted sexual advance on him when he was 14."
