Berlusconi promises to quit if he is proved to be a liar

Embattled Italian premier Silvio Berlusconi today promised he would resign immediately if he were shown to have lied about his relationship with an 18-year-old model at the heart of a scandal that has gripped the country for weeks.

Berlusconi made the promise after Spanish newspaper El Pais published photographs of topless women and a naked man lounging at his Sardinian home.
