Thomas Kingston, the husband of Prince and Princess Michael of Kent’s daughter Lady Gabriella Kingston, died from a gunshot wound to the head.
A public hearing at Gloucestershire Coroner’s Court revealed that the 45-year-old died last month from a “traumatic head wound”.
A gun was found near to his body in an outbuilding at his parent’s home in the Cotswolds.
The court hearing has been adjourned for the Coroner to collect further evidence ahead of an inquest later in the year.
It is understood that there are no suspicious circumstances or third party involvement in his death.
Mr Kingston, who has died at the age of 45, married Lady Gabriella Windsor, daughter of Prince & Princess Michael of Kent, in May 2019.
A statement from Mr Kingston’s immediate family on Tuesday reads: “Tom was an exceptional man who lit up the lives of all who knew him. His death has come as a great shock to the whole family and we ask you to respect our privacy as we mourn his passing.”
A Buckingham Palace spokesperson said: “The King and the Queen have been informed of Thomas’s death and join Prince and Princess Michael of Kent and all those who knew him in grieving a much-loved member of the family.
“In particular, Their Majesties send their most heartfelt thoughts and prayers to Gabriella and to all the Kingston family.”
