Prince Harry and Meghan Markle are honouring “mums all over the world” in celebration of Mother’s Day.

On Sunday, the Duke and Duchess of Sussex shared an Instagram post to their official account that reads: “Mummy. Mum. Mom. Mama. Granny. Nan. Thank you.”

The couple captioned the picture: “No matter what you call your mum, this Mother’s Day in the UK, we honour the mums all over the world who do so much every single day, and now more than ever.

“Thank you.”

In response to the post, many wished Meghan, who gave birth to the couple’s first child, Archie Harrison, on 6 May 2019, a happy first UK Mother’s Day.

“Happy First official Mother’s Day to you Meghan. I hope you are happy and thriving!” one person wrote.

Another commented: “Happy first Mother’s Day Meghan!”

While this is the duchess’s first UK Mother’s Day, it is not the first time she and Prince Harry have celebrated her first Mother’s Day as a mother - as the couple celebrated the American version of the holiday last year on 12 May, just days after Archie’s birth.

At the time, the couple shared a photo of Meghan holding the newborn’s feet.

“Paying tribute to all mothers today - past, present, mothers-to-be, and those lost but forever remembered,” the duke and duchess captioned the picture. “We honor and celebrate each and every one of you.

“Today is Mother’s Day in the United States, Canada, Australia, New Zealand, South Africa, Kenya, Japan, and several countries across Europe. This is the first Mother’s Day for the Duchess of Sussex.”

It is likely that the couple, who are currently residing in Canada after formally stepping down from their senior roles in the royal family, will celebrate a second Mother’s Day this year, on Sunday 10 May.

Earlier in the day, the Duke and Duchess of Cambridge also shared a Mother’s Day post on Instagram, where they shared a photo of Prince William and Prince Harry with their late mother Princess Diana and a photo of Kate Middleton and her mother Carole.
