Lady Gabriella Kingston has warned about the effects of drugs used to treat mental health problems, as a coroner concluded that her husband took his own life.
Thomas Kingston, the husband of Prince and Princess Michael of Kent’s daughter Lady Gabriella, died from a head injury, and a gun was found near his body on February 25, at his parents’ home in the Cotswolds.
Mr Kingston, a 45-year-old financier, married Lady Gabriella at Windsor Castle in 2019, with Queen Elizabeth II and the late Duke of Edinburgh among the guests.
The inquest into his death at Gloucestershire Coroner’s Court on Tuesday was told he had initially been given sertraline, a drug used to treat depression, and zopiclone, a sleeping tablet, by a GP at the Royal Mews Surgery, a practice at Buckingham Palace used by royal household staff, after complaining of trouble sleeping following stress at work.
Mr Kingston returned to the surgery saying they were not making him feel better, and his doctor moved him from sertraline to citalopram, a similar drug.
In the days leading up to his death, Mr Kingston had stopped taking medication, and toxicology tests showed caffeine and small amounts of zopiclone in his system.
In a statement read out by Katy Skerrett, senior coroner for Gloucestershire, Lady Gabriella, 43, said: “(Work) was certainly a challenge for him over the years but I highly doubt it would have led him to take his own life, and it seemed much improved.
“If anything had been troubling him, I’m positive that he would have shared that he was struggling severely.
“The fact that he took his life at the home of his beloved parents suggests the decision was the result of a sudden impulse.”
She said she believed his death was “likely provoked” by an adverse reaction to the medication he had begun, and subsequently stopped, taking, in the weeks leading up to his death.
“The lack of any evidence of inclination, it seems highly likely to me that he had an adverse reaction to the pills that led him to take his life,” Lady Gabriella said.
“I believe anyone taking pills such as these need to be made more aware of the side effects to prevent any future deaths.
“If this could happen to Tom, this could happen to anyone.”
In his final weeks, Lady Gabriella said, her husband had “seemed normal”, apart from early in the day after previously taking zopiclone, which she said made him seem “almost hungover”.
In her statement, she described their marriage as “deeply loving and trusting” and said he had never expressed any suicidal thoughts to her or others.
She added that he had been deeply affected by the suicide of a friend and the “devastating impact it had on other people’s loved ones”.
Lady Gabriella cried while she sat in the coroner’s court as her statement was read out.
Recording a narrative conclusion, Ms Skerrett said: “Mr Kingston took his own life using a shotgun which caused a severe traumatic wound to the head.
“The evidence of his wife, family and business partner all supports his lack of suicidal intent.
“He was suffering adverse effects of medication he had recently been prescribed.”
She said she intended to draft a prevention of future deaths report, which would be sent to medical bodies.
Mr Kingston’s father, William Martin Kingston, broke down in tears as he described finding his son in the locked bathroom of a detached annexe, having used a crowbar to break down the door.
He told the court his son had always had a strong, resilient character, having previously suffered from a pain condition which left him needing help to get up the stairs.
He told the coroner that leading up to his son’s death there did not appear to have been any searches for suicide, and no will or note was left, describing the method as “very ragged” which was simply “out of character”.
