Frank Sinatra's daughters NANCY and TINA refuse to acknowledge allegations linking their father to the mob - insisting his fans are sick of reading about conspiracy theories.

Since his death in 1998 a number of books have been released suggesting Sinatra's connections to the American mafia.

But the pair - Sinatra's children with first wife NANCY BARBATO - have dedicated their lives to promoting positive aspects of their father's life.

Nancy says, "We don't read that stuff. It doesn't exist for us. We give people ammunition with which to fight the garbage that comes out.

Tina adds that Americans are sick of reading conspiracy theories about her father: "Whatever books in this country have come out have sold no copies. People don't care. They are fed up with it."
