“However, Prince Edward and Miss Rhys-Jones hope that it might be possible to use St George’s Chapel, Windsor in the late spring or summer.”

After the announcement was made, the couple posed for an official photocall at St James’s Palace.

During the appearance, Sophie showed off her engagement ring for the first time.

The Countess will still regularly wear her ring when attending royal engagements.

DON’T MISS

What is her engagement ring like?

The stunning ring has a two-carat central oval diamond.

The diamond is flanked between two small heart-shaped jewels and set on an 18-carat white gold band.

The eye-catching piece is reportedly worth £110,000 and was bought from Asprey Garrard, now Garrard & Co.

Before Sophie’s engagement ring was bought, the jewel made Princess Diana’s famous sapphire and diamond ring.

This ring was given to Kate Middleton by Prince William when he proposed in 2011, as she still regularly wears it.

Garrad also notably created the Girls of Great Britain and Ireland tiara often worn by Queen Elizabeth II.

When Sophie married, she was given a wedding band made from Welsh gold, in line with royal tradition.

The royal line of succession – who outranks who?

The line of succession to the British throne dictates the order in which each member of the Royal Family would ascend to the throne.

It is also seen as a ranking of importance with the head of the line, the Queen, taking the place of ruler.

Older children come before younger children. Traditionally boys came before girls, but this law was changed on 26 March 2015 before the birth of Prince William’s first child.

Incredibly, Catholics are still excluded from the line of succession, as are children born outside of wedlock.

The royals, who usually stick to a strict protocol when appearing in public, often arrive at events in ascending order of importance, with the most important royal arriving last.

Prince Charles, 72, is currently first-in-line to the British throne, followed by Prince William, 38, his oldest son.

Then comes Prince William’s children, George, seven, Charlotte, five, and Louis, two, and they are followed by Prince Harry, 36. Prince Harry is succeeded by his son Archie Harrison, born in May 2019.
