An inquest into the death of India-born UK nurse Jacintha Saldanha, found hanged after she took a hoax call at a hospital in London about Kate Middleton's first pregnancy, opened here today.

The 46-year-old was found in the nurses' quarters of the King Edward VII hospital in London days after the prank phone call from two Australian radio presenters posing as Queen Elizabeth II and Prince Charles.

Saldanha had put the call through to the ward where Kate, Duchess of Cambridge, pregnant with Prince George, was staying and another nurse there had revealed confidential medical details.

Westminster Coroners' Court is sitting at the Royal Courtsof Justice in London for the inquest, which is expected to last two days.

"It has been a long road for the family and I deeply admire the patience, humility and dignity they have shown throughout this traumatic time. It is right that they finally gain closure," said senior Indian-origin Labour MP Keith Vaz, who is acting as the family's spokesperson.

The inquest, which has been delayed by almost a year,comes soon after the announcement that Kate is pregnant again and suffering acute morning sickness just as on December 4, 2012, when Saldanha took the prank call.
