At one minute past 11 (BST) on the morning of 23 April 2018, The Duke and Duchess of Cambridge welcomed their third child into the world. Weighing 8lb 7oz, the new prince was born at the Lindo Wing of St Mary’s Hospital, in London, where his two siblings were also born. Following the announcement of the birth, a framed notice was placed on an ornate easel on the forecourt of Buckingham Palace, as is tradition. Flags were also raised at Buckingham Palace and Windsor Castle to mark the birth of the new prince.

The name of His Royal Highness Prince Louis Arthur Charles has strong and varied connections through the royal family. The new prince’s great-great-great uncle was Lord Louis Mountbatten, who was influential in the life of HRH Prince Charles Philip Arthur Louis, the young prince’s paternal grandfather. The prince’s full name resonates further through those of his father, HRH Prince William Arthur Philip Louis; his uncle, HRH Henry Charles Albert David; and his brother HRH George Alexander Louis. Under the letters patent issued by Queen Elizabeth II in December 2012, all children of Prince William are styled “Royal Highness”, thus the new prince is known as HRH Prince Louis of Cambridge.

Prince Louis is fifth in line to the British throne, after his grandfather, Prince Charles; his father, Prince William; and his two siblings Prince George and Princess Charlotte.

$1 The Duke and Duchess of Cambridge, with Prince Louis

The stamp design takes a simple and restrained approach, with the use of gold-coloured ink through the typography and frame to emphasise the royal theme. As in the stamps that marked the births of the new prince’s two siblings, the photograph shows the royal couple with Prince Louis outside St Mary’s Hospital.
