Baby Archie makes first official public appearance

The world has received its first official glimpse of the newest addition to the royal family.

Archie Harrison Mountbatton-Windsor, the two-month-old son of Prince Harry and Meghan Markle, was christened at Windsor Castle on Sunday (NZ time) in a private ceremony.

The Duke and Duchess of Sussex released two official photographs from the day that include Archie - the first of their kind since he was born.

In one group shot, Archie is photographed in his mother's arms alongside the Duchess of Cornwall, the Duke of Sussex, the Duchess of Cambridge, the Prince of Wales, Doria Ragland, Lady Jane Fellowes, Lady Sarah McCorquodale and the Duke of Cambridge.

In a second black-and-white image just the young family are pictured, with Markle holding Archie while Prince Harry leans over him.

The christening itself was understood to be a "very small gathering", according to AAP, and details of Archie's new godparents have been kept secret.

One of the images was shared to the Duke and Duchess of Sussex's Instagram account along with a message saying how much they enjoyed the day.

"The Duke and Duchess of Sussex are so happy to share the joy of this day with members of the public who have been incredibly supportive since the birth of their son. 

"They thank you for your kindness in welcoming their first born and celebrating this special moment."

The post went on to describe how Archie was baptised wearing a handmade replica of the royal christening gown which was commissioned by Queen Victoria in 1841.
