Italian Premier Silvio Berlusconi asked women guests at a party in his private villa to call him as "Papi" in case their phones were being tapped,his former employee has claimed. According to Elisa Alloro,formerly with Berlusconi's TV network,the term "Papi" had been used by many of his women friends for some time and was indeed a codename in case their conversations were overheard. "The Prime Minister is a mine of wisdom. I have always considered every moment I've spent with him a gift from God," Elisa Alloro,a former staffet of Berlusconi's TV network,was quoted by 'The Times' as saying. Alloro has also said that she "vaguely remembered" Ms Letizia,the teenage lingerie model said to be the main cause behind Berlusconi's divorce,at the villa at the party,which she has attended with a number of female friends. In fact,the claims,made in 32-year-old Alloro's upcoming book,came after the Italian media revealed details of parties at Villa Certosa,Berlusconi's Sardinian villa,including photos showing topless women,the British daily said. According to the Italian media reports,some of the pictures of the parties show topless women embracing under a shower beside a swimming pool. However,Berlusconi was clothed in all the photographs,some of which showed him driving girls round his estate in a golf buggy while armed guards stood on the perimeter wall.
