Prince William joins mourners at Thomas Kingston's funeral: Wife Lady Gabriella Windsor and her parents Prince and Princess Michael of Kent attend private service at the Chapel Royal in St James's Palace after his sudden death aged 45

Thomas Kingston was given a royal send-off today in a funeral attended by Prince William and other members of the Royal Family. 

The body of the financier, who was found dead last month aged 45, was carried in a procession that began at Kensington Palace, the family home of his widow, Lady Gabriella Windsor.

The procession ended at Ambassador's Court at St James's Palace. A private family funeral was then held at the Chapel Royal, where many royal weddings have taken place including that of Queen Victoria and Prince Albert in 1840. 

More recently, Prince George, the elder son of the Prince and Princess of Wales, was christened there in 2013. And while William was present, Kate remained at home, continuing to recover from abdominal surgery she underwent in January.

Lady Gabriella was joined at the funeral by her parents, Prince and Princess Michael of Kent, her brother, Lord Frederick Windsor and his wife, the actress Sophie Winkleman.

The Duke of Kent and Princess Alexandra were also present in the congregation of 140 people.

The King - Lady Gabriella's second cousin - and the Queen were not present.

Charles is not attending public-facing events while he undergoes treatment for cancer, and the Queen was hosting a WOW (Women of the World) reception at Buckingham Palace.

The body of Mr Kingston was later cremated.

Mr Kingston and Lady Gabriella, known as Ella, were married at St George's Chapel, Windsor, in a ceremony attended by Prince Michael's first cousin, Queen Elizabeth, and Prince Philip in 2019.

They lived in London but he had been visiting his parents at their home in the Cotswolds when he died.

A coroner's court was told: 'His father went out to walk the dogs. On his return Mr Kingston was not in the house. After approximately 30 minutes his mother went to look for him.'

Katy Skerrett, the senior coroner for Gloucestershire, added: 'His father forced entry into a locked outbuilding. Mr Kingston was found inside with a catastrophic head injury. A gun was present at the scene. Police are satisfied the death is not suspicious.'

The coroner said a post-mortem examination had been undertaken and a provisional cause of death had been determined as a traumatic wound to the head. She formally opened the inquest into the death and adjourned it.

Announcing his death last month, Buckingham Palace described Kingston, a financier, as a 'much-loved member of the family' who was being mourned by King Charles and Queen Camilla. A friend of the couple said: 'They remained childless but were happily married until the end.'

After studying economic history at the University of Bristol, Kingston joined the diplomatic missions unit of the Foreign Office in Iraq, working as a project officer for the Iraqi Institute of Peace from 2003 to 2006.

Last month, Lady Gabriella paid tribute to her husband in a joint statement with his family, describing him as an 'exceptional man who lit up the lives of all who knew him' - and called his death a 'great shock to the whole family'.

She released a personal photo she took of her husband, showing him smiling and dressed in a casual pink shirt as he stood near a stretch of water in the sunshine.

The couple married at St George's Chapel, Windsor Castle, in 2019 with Queen Elizabeth II and her husband, the late Duke of Edinburgh, among the guests.

Lady Gabriella is the King's second cousin. They are both great-grandchildren of King George V.

Mr Kingston was a director of Devonport Capital, which specialises in providing finance for companies in 'frontier economies'.

He was a close friend of Pippa Matthews - the Princess of Wales's sister - and the pair were said to have dated in 2011.

Lady Gabriella, who has worked as an arts and travel director for a brand company, is a writer and contributing editor.

She is also a singer-songwriter and released two bossa nova-inspired tracks in 2020 to raise money for charity.

Lady Gabrielle and her husband were last pictured in public together on Valentine's Day at an event to celebrate the works of William Shakespeare.
