The King and Queen are “delighted” with the engagement of Charles’ nephew in what will be the first royal wedding in years.

Peter Phillips, the son of Princess Anne, announced his engagement to NHS nurse Harriet Sperling on Saturday (AEST).

The 47-year-old  — whose parents are Captain Mark Phillips and Charles’s younger sister — and his fiancé had been dating for a year.

Both have previously been married.

“Both families were informed jointly of the announcement and were delighted with the wonderful news of their engagement,” read a statement issued on the couple’s behalf.

“Their Majesties The King and Queen, The Prince and Princess of Wales have been informed of the announcement.”

At the moment there is no official date for the wedding.

Peter — who was the eldest grandchild of the late queen — was fifth in line to the throne at birth and remained so until the birth of his cousin William, Prince of Wales, in 1982.

Peter has two daughters, Savannah and Isla, from his relationship with his ex-wife Autumn Kelly.

The pair, who wed in 2008, announced their separation in February 2020 and their divorce was finalised in June 2021.

A statement released at the time read: “Whilst this is a sad day for Peter and Autumn, they continue to put the well-being and upbringing of their wonderful daughters Savannah and Isla first and foremost.

“Both Peter and Autumn are pleased to have resolved matters amicably with the children firmly at the forefront of those thoughts and decisions.

“Peter and Autumn have requested privacy and consideration for their children as the family adapts to a new chapter in their lives.”

After his separation from Autumn, Peter was in a relationship with Lindsay Wallace for three years.

While dating, they attended several royal family events together, including King Charles’ Coronation Concert at Windsor Castle.

Peter and Harriet — who has a daughter, Georgia — first went public as a couple in May 2024 when they were seen at the Badminton Horse Trials in Gloucestershire, England.

Later that same summer they were seen enjoying Wimbledon sat in the royal box.

Harriet has accompanied Peter to numerous events with other members of the royal family such as the Royal Ascot race meet.

Peter and Harriet’s engagement announcement comes just one day after Princess Diana’s niece Lady Eliza Spencer took to Instagram to reveal she had got engaged to her long-time boyfriend Channing Millerd in Santorini, Greece.
