Princes William and Harry attended their uncle's funeral but did not communicate with each other

Princes William and Harry attended the funeral of Lord Robert Fellowes, 82, the brother-in-law of their mother Princess Diana, but kept their distance from each other, The Sun reports. Harry, 39, flew to the UK for the funeral but sat apart from his brother William, 42, at the funeral at a church in Snettisham.

A close family friend confirmed that both princes were at the service, but were only spotted at the end of the ceremony. The brothers were seated in the back rows, far apart. "I didn't know they were there. They arrived very quietly."

A local told the publication that Harry and William, who have long been at odds with each other, had failed to speak to each other again. "William and Harry were both there, but we didn't see them talking - they were keeping their distance."

The late Lord Robert Fellowes was a member of the royal family on his mother's side. He was married to Princess Diana's sister, Lady Jane Spencer, from 1978. Robert served as Queen Elizabeth's private secretary from 1990 to 1999, becoming one of her closest advisers during the difficult period that included Princess Diana's death.

The relationship between the brothers deteriorated a couple of years ago. After moving to the United States with his wife Meghan Markle, Harry released a memoir, "The Spare," and gave several high-profile interviews, revealing unpleasant details about life in the royal family. Later, Harry tried several times to improve relations with William and his father, but so far this has not happened.

This spring, it became known that Prince William's wife, 42-year-old Kate Middleton, had been diagnosed with cancer. Earlier, King Charles III of Great Britain also reported an oncological disease.
