Dominique Strauss-Kahn had no way of knowing he was sleeping with prostitutes during swinger sessions because "the women were all naked at the time", his lawyer has claimed. The defence came amid allegations his mobile phone records showed he had relationships with 10 call girls. A host of recent revelations have already established the insatiable sexual appetite of the 62-year old one-time French presidential favourite. But the new records could help police determine whether the former International Monetary Fund chief was aware that the women he had sex with had been paid to do so. Sleeping with prostitutes is legal in France if the girls are over 18 but some warn Mr Strauss-Kahn could face charges if the case expands to cover graft or procuring. The 10 French or Belgian women to whom police traced calls to Mr Strauss-Kahn, all claim to have had paid sex with him while he was IMF chief right up to his arrest last May on charges he tried to rape a New York hotel chambermaid. http://www.telegraph.co.uk/finance/...-prostitutes-because-they-were-all-naked.html
