The Duke and Duchess of Sussex announce royal baby name and title

The Duke and Duchess of Sussex have named their baby Archie Harrison Mountbatten-Windsor, it has been announced.

The couple posted the news on their Instagram page, along with a black and white photograph of the newborn baby being introduced to the Queen and Duke of Edinburgh.

With the Duchess' mother Doria Ragland by their sides, the duchess held the baby in her arms as the Queen beamed.

The announcement appears to confirm that the baby will not take a title.

While the bookies had safely predicted the names of Prince George and Princess Charlotte, they were left confounded by the Sussex's selection.

In the days after the baby boy's birth, they had settled on Alexander, Arthur, James, Philip and Spencer as the most likely options, with their punters preoccupied with how the couple would honour the late Diana, Princess of Wales.

By Wednesday, when the baby was two days old, senior members of the Royal Family including his Uncle William and Auntie Catherine had not yet been made aware of the name.

Bookies, who until Monday had overwhelmingly predicted the baby would be a girl, have tipped Alexander and Arthur as the front-runners for a boy’s name, with a longlist imbued with tradition.

Spencer was yesterday inching into the lead at William Hill, after fans adopted it as a favoured choice on social media in honour of Diana, Princess of Wales.

The Duke has previously spoken of how important it is to him to include his late mother in the big moments of his life, saying during his engagement interview that incorporating her diamond in to the Duchess’ ring would “make sure that she's with us on this crazy journey together”.
