The new Prince of Cambridge has been born fifth in line to the throne - bumping Prince Harry out of the top five.
Harry is unlikely to mind shifting down to sixth place.
When the Duchess of Cambridge was pregnant with Princess Charlotte in 2014, it was put to Harry that the new addition to the royal family would further reduce his own chances of being King.
The prince merely laughed and replied: "Great!"
The Duke of York, who was born second in line in 1960, has moved to seventh in the line of succession.
Andrew, who is divorced from but remains close to his ex-wife Sarah, Duchess of York, no longer needs to ask the Queen's permission should he wish to re-marry.
The Succession to the Crown Act 2013 requires only the first six people in the line of succession to ask for the monarch's consent.
The duke's daughters, Princesses Beatrice and Eugenie, are now eighth and ninth.
The Earl of Wessex, born third in line, is in 10th place, while his 10-year-old son, Viscount Severn, has dropped out of the top 10 into 11th place.
