Prince George and Princess Charlotte to be separated by rules in 2025?

Prince William and Kate Middleton are often seen with their three children, Prince George, Princess Charlotte and Prince Louis.

But two of their kids are going to be separated by the rules that govern the royal family. 

When Prince George turns 12 he will no longer be allowed to travel with Charlotte due to the rules of the line of succession.

British royal protocol prevents the immediate heirs to the throne from flying together. This rule is in place to ensure the monarchy's future in the event of an accident

This would be enforced to make sure the next heir if something happens to George remains safe. The rule also applies to George and Prince William.

It may be upsetting for the siblings but such measures are important to secure the future of the monarchy and the royal family.

In the royal family it's prohibited for two individuals who are high in the line of succession to travel in the same vehicle.

This rule aims to minimize the risk of losing two heirs at once in the event of an accident or emergency.

William and Kate Middleton are allowed to travel with their children while they are young, however, as heirs like Prince George grow older they will need to travel separately.

Under the British constitution, a sovereign succeeds to the throne the moment his or her predecessor dies, before being proclaimed to the people, so there is no interregnum.

The rules, most of which date back hundreds of years, mean the crown passes to the monarch's eldest child, and the line is then dictated by birth order and closeness to the existing sovereign.

So, Charles' eldest son Prince William is the heir to the throne, followed by William's eldest son Prince George, 11, and then his younger children Charlotte, 9, and Louis, 6.

Prince Harry, Charles' younger son and William's brother, is then next in line.
