Well, the wait is finally over. The royals have revealed to the world the name of the newest addition to the royal household just four days after his birth.

It's—drumroll, please—Louis Arthur Charles.

The Duchess of Cambridge gave birth to him shortly after 11 a.m. BST on Monday, 23 April. Weighing 8lb 70z, little Louis is fifth in line to the throne.

The name Arthur was bookmakers' first choice with odds of 5/1. Philip and Thomas were also among the top picks. The odds for the name Louis were 18/1.

The Duke and Duchess of Cambridge are yet to reveal the reasons behind the choice of name, but it could well be a tribute to Lord Louis Mountbatten, a well-loved relative of the royal family who became a close friend and mentor to Prince Philip and Prince Charles. Mountbatten died in an IRA attack in 1979.

Kate and William took two days to announce the names of both Charlotte and George, and the Queen was also informed of their choice prior to the announcement.

Thanks to a law that was passed in 2013, Princess Charlotte's position in the line of succession is unchanged following the birth of her younger brother Louis. Prior to the passing of this law, the birth of a younger male heir would affect an older female heir's position in line to the throne.

Welcome to the world, prince Louis!
