According to Kensington Palace, the name of the baby would be announced in due course while a formal notice of the birth had been posted on the forecourt of Buckingham Palace.

Favorite names at the bookmakers include Arthur, Albert, Frederick, James and Philip.

PM Theresa May tweeted her “warmest congratulations” to Prince William and his wife.

Following a change in the law in 2013, Princess Charlotte keeps her place as fourth in line to the throne.

Previously, younger royal males would have taken precedence over older female siblings.
