The Earl and Countess of Dumbarton have announced they are expecting their second child.

Harry and Meghan are preparing to welcome a brother or sister for their son, Archie Mountbatten-Windsor, who will be turning two on May 6.

A Buckingham Palace spokesman said that Queen Elizabeth, the Duke of Edinburgh, Prince of Wales and the rest of the Royal Family "are delighted and wish them well".

The couple - who were given the titles of Earl and Countess of Dumbarton by the Queen on the day of their wedding in May 2018 - shared the news on Sunday evening with a black and white picture of themselves under a tree, with Harry resting his hand on Meghan's head as she cradles her prominent bump.

The due date has not yet been revealed, but their child will be eighth in line to the throne.

This news comes after the Duchess revealed in November last year that she has suffered a miscarriage last July, writing in an article of feeling "an almost unbearable grief".

In a nod to Harry's mother, the couple shared their pregnancy news exactly 37 years to the date when Princess Diana announced she was expecting her second child.

Misan Harriman, a friend of the Duke and Duchess of Sussex and the photographer who took the photo that accompanied their pregnancy announcement, tweeted: "Meg, I was there at your wedding to witness this love story begin, and my friend, I am honoured to capture it grow.

"Congratulations to The Duke and Duchess of Sussex on this joyous news!"
