The siblings of Diana, Princess of Wales will look on as their beloved nephew Prince Harry marries Meghan Markle.

Taking their seats in St George’s Chapel, Earl Spencer, Lady Sarah McCorquodale and Lady Jane Fellowes will represent a link to Harry’s late mother.

Lady Jane will give a reading at the ceremony, Kensington Palace announced.

Both sisters read poems at Diana’s funeral, while Earl Spencer gave a controversial eulogy which was seen as an attack on the royal family.

He vowed to Diana in his speech that her ”blood family” would do all they could to protect the Duke of Cambridge and Harry ”so that their souls are not simply immersed by duty and tradition but can sing openly as you planned”.

Earl Spencer is the youngest of Diana’s siblings, with Lady Sarah being born nine months after their mother, Frances Roche, later Frances Shand Kydd, married Edward John “Johnnie” Spencer in 1954.

Three years later Jane was born. She would become Lady Jane Fellowes after marrying the Queen’s former assistant private secretary, Sir Robert Fellowes.

Diana was born in July 1961, followed three years later by brother Charles, who went on to become Earl Spencer.

Just 16 days after her death in 1997, Harry’s aunt Lady Sarah arrived at Ludgrove, Harry’s Berkshire prep school, and presented him with a computer play station, the gift Diana had planned to give him.

It was Lady Sarah who introduced Diana to the Prince of Wales, having briefly dated Charles in the late 1970s.

Footage of William, 15, and Harry, 12, walking behind their mother’s coffin was beamed to the world.

Last year Earl Spencer claimed he was “lied to” about the desire of the brothers to do so.

He said walking behind Diana’s coffin in the funeral cortege was the “most horrifying half hour of my life”, but that he believed the experience was a “million times worse” for Diana’s sons.

Announcing the attendance of his maternal aunts and uncle on the big day, Kensington Palace said Harry was “keen to involve his mother’s family in his wedding”.
