Italian Prime Minister Silvio Berlusconi's daughter has said she was amazed by the attention her father lavished on a teenage model, in a rare criticism of the scandal-hit leader by one of his children. Barbara Berlusconi, 25, also told Vanity Fair that politicians ought to uphold the values they preach publicly in their private lives - in contrast to Berlusconi's allies who say his personal life has no bearing on his public role. When asked what she thought of the attentions her father had shown toward Letizia, Barbara said: “I was shocked. It's something that has never been part of my life.” “Political representatives that are called to govern well, make society prosper, are also held to safeguard the values they express, possibly raise them,” Barbara told the magazine. “So I don't believe a politician can allow a distinction between his public and private life.” Barbara is one of three children Berlusconi has with Veronica. His two children from his first marriage hold prominent positions in his business empire.
