Prince William and the Duchess of Cambridge have announced that they are expecting their third child.
Buckingham Palace told everyone the news on Monday morning, adding that the Queen is “delighted”.
William and Kate’s third child will become the fifth person in line to the throne. The new child will be behind their granddad, Prince Charles, dad, Prince William, and siblings Prince George and Princess Charlotte.
If it is a boy, Charlotte will be the first girl to be ahead of their brother in the line to the throne. This is because of new rules that started in 2015.
The news marks a big week for Kensington Palace. Four-year-old Prince George is due to start school on Thursday.
