The Duke and Duchess of Sussex are celebrating with their families today following the birth of their newborn son.

The new arrival was welcomed into the world shortly before 5.30am on Monday, May 6 by proud parents Harry and Meghan, and grandmother Doria Ragland, who is said to be staying with the couple at their home in Windsor.

Talk has already turned to what name will be given to the new baby boy - and whether or not the royal couple will stay traditional or sway in favour of something more modern.

Odds from online gambling company Betfair seem to point towards the former.

Katie Baylis, spokeswoman for Betfair, said: “It’s the news the world has been waiting for for days and now that the royal couple have announced they have had a little baby boy, attention now turns to what the little prince’s name will be.

"James and Alexander are the joint favourites at 7/2, both slashed from 12/1 after a flurry of bets on both names in the last few hours.
