Last month would have marked her fifth wedding anniversary with financier Thomas, who was found dead at the age of 45 at his parents' home in the Cotswolds on 25 February.

An inquest at Gloucestershire Coroner's Court on 1 March found that Thomas died from a "catastrophic head injury" and a gun was found near his body. His death was not treated as suspicious, and no one else was involved.

He and Gabriella told the knot on 18 May 2019 at St George's Chapel in Windsor, with the late Queen Elizabeth II, the late Duke of Edinburgh and Prince Harry among the guests.

The funeral took place on 12 March at the Chapel Royal in St James's Palace with Lady Gabriella, her parents Prince Michael and Princess Michael of Kent and the Prince of Wales in attendance.
