The family of a man killed in a horrific helicopter crash are suing the widow of the pilot at the controls.
Charles Stisted, a close friend of Prince Charles, William and Harry, died when the craft smashed into a mountain in Northern Ireland on the way back from a hunting trip.
The 47-year-old father-of-two was killed alongside pilot Anthony Smith and the aircraft's co-owner, construction tycoon Ian Wooldridge. Today Mr Stisted's grieving wife Melissa revealed she is suing Mr Smith's widow, Angela, as well as Mr Wooldridge's family, for [pounds sterling]300,000. They believe the pilot was negligent.
