Former prime minister Silvio Berlusconi has blamed "feminist, communist" judges for a $258,000-a-day divorce settlement following the breakup of his second marriage.

Berlusconi told the private La7 television network on Tuesday that he was appealing the settlement with ex-wife Veronica Lario.

Italian media initially reported the settlement amounted to $129,000 a day.

But Berlusconi said the figure, with arrears, was double that.

 "These are three women judges, feminists and communists, OK? These are the Milan judges who have persecuted me since 1994," he said.

Lario filed for divorce in 2009, citing Berlusconi's fondness for younger women.

Last month, the 76-year-old media baron announced his engagement to 28-year-old Francesca Pascale.

The billionaire is currently on trial, accused of paying for sex with an underage Moroccan teen and using his office to cover it up. He and the girl deny the charges.
