Rupert Murdoch files for divorce from Wendi Deng

News Corp boss Rupert Murdoch has filed for divorce from Wendi Deng because their marriage has "irretrievably broken down.''

The divorce papers were filed at the New York State Supreme Court.

The couple were married in 1999 aboard a private yacht in New York and have two daughters together, Grace and Chloe.

In 2011, Wendi Deng famously leapt to her husband's defence to slap a protester who threw a foam pie at him as British MPs quizzed him over phone-hacking.
