Kate Middleton and Prince William have named their third child Louis Arthur Charles.
Prince Louis was born on April 23 at the Lindo Wing of St Mary’s Hospital in London, weighing 8lb 7oz.
According to a statement issued by Kensington Palace, Kate Middleton and Prince William’s second son would be known as His Royal Highness Prince Louis of Cambridge (pronounced Lou-ee, not Lou-iss).
Prince Louis is fifth in line to the throne.
Louis is also one of the middle names of Prince William and of the new prince’s older brother, George.
It was also the first name of Lord Mountbatten – his great-great-great uncle – who was killed by the IRA in 1979.
Lord Mountbatten had a strong influence in the upbringing of great-nephew Prince Charles and was described by the latter as “the grandfather I never had”.
Arthur is also one of Prince William’s middle names, and was a middle name of King George VI – Queen Elizabeth’s father.
