MINING billionaire Gina Rinehart has accused her eldest daughter — who grew up in a Perth mansion, enjoyed ocean-cruise holidays and was educated at an exclusive American school — of leaking family company secrets.
The explosive claim against Bianca Rinehart, contained in a legal letter seen by The Daily Telegraph, comes as the Rinehart feud heads to court in Sydney today.
Lawyers for Ms Rinehart’s company accuse Bianca of “unlawful and dishonest conduct” in a letter handed to the Supreme Court judge presiding over the bitter family battle for control of a $5 billion family trust.
