Prince George to be separated from Princess Charlotte when royal rule comes into force

This is because Prince William and Princess Kate’s eldest child, 10-year-old George is second in line to the throne after his father.
A royal rule that limits which royals can travel together to the same place will come into effect when the young Prince turns 12 in July 2025.
According to King Charles’s former pilot, Graham Laurie, the same rule applied to William once he turned that age in 1994.
“We flew all four: the Prince, the Princess, Prince William and Prince Harry, up until Prince William was 12 years old”, Laurie told OK!.
“After that, he had to have a separate aircraft and we could only fly all four together when they were young with the written permission of Her Majesty.
“When William became 12, he would fly normally in a 125 from Northolt and we would fly the 146 out with the other three on.”
The rule, which is meant to secure the heirs to the trone, will come into effect for the young prince next year.
