Buckingham Palace has confirmed that the Duchess of Cambridge has been admitted to St. Mary’s Hospital, Paddington, London in the early stages of labour.
The Duchess travelled by car from Kensington Palace to the Lindo Wing at St. Mary’s Hospital with The Duke of Cambridge.
The same hospital is where Prince William and his brother Prince Harry were born.
It could be 10 days before the baby's name is announced. British people favour the names Alexandra, Charlotte, Elizabeth, Victoria, Grace, James and George. The field is open for both boys' and girls' names because the parents did not want to know their child's sex in advance.
The child's title will be His or Her Royal Highness Prince or Princess (the baby's name) of Cambridge.
Protocol dictates that the first to know about the arrival of the baby will be Queen Elizabeth II, Prime Minister David Cameron and the governors general of each of the Commonwealth Nations -along with the rest of the Royal Family and the Middleton Family.
The baby will be third in line to the throne after Prince Charles and Prince William, regardless of gender. A rule change in 2011 (More Queens in the future?) ended centuries of male primogeniture, which decreed that the crown passed to the eldest son and was bestowed on a daughter only when there were no sons. It means that if the next royal baby is a girl, she will eventually become queen; previously, a younger male sibling would have taken precedence.
