The Royal baby has been named Prince Louis Arthur Charles Cambridge in a nod to Prince Charles' beloved great uncle Lord Mountbatten - here's what you need to know
The Duchess of Cambridge gave birth to a son at 11.01am on Monday morning weighing 8lbs 7oz, inside the £5,900-a-stay The Lindo Wing at St Mary's Hospital in London.
After the Queen, other members of the Royal family and the Middleton family were told the good news, the royals' team emailed media organisations with the sex, weight and timing of the birth before tweeting the details.
Arthur, Albert, Philip or James...
As the Royal baby name wait goes on, observers will no doubt look into the history books in search for the couple's motivation.
When the Duke and Duchess of Cambridge pick a name for their newborn son, it is likely to be one that carries the weight of history with it; something meaningful; something with precedent.
So while Ethan, Logan and Jaxon were all popular last year, they are unlikely to be bestowed upon the younger brother of Prince George and Princess Charlotte.
