London, May 23 : Italian Prime Minister Silvio Berlusconi's reputation received another blow when pictures of him and Noemi Letizia, the 18-year-old accused of being at the heart of his divorce, were published showing them attending a Christmas party given by AC Milan, the football club that he owns.

Photographs and a video clip were published by La Repubblica, the newspaper, on its website showing Letizia attending the party with her mother, Anna Palumbo, reports The Times.

The latest "development" will further fuel Berlusconi's second wife Veronica Lario's anger who has requested a divorce after he attended the 18th birthday party of Letizia last month and gave her a 5,200-pound diamond pendant.

Lario asked for a divorce, saying that Berlusconi had not attended the 18th birthday party of any of their three children, and adding: "I cannot stay with a man who frequents minors".

In his defence, Berlusconi claims that he knows Letizia and her mother through Benedetto Letizia, Palumbo's husband and Letizia's father, who is a Naples council employee, describing him as "an old friend". (ANI)
