Prince George and Princess Charlotte about to be deprived of a precious gift

Members of the British royal family are often criticized by  anti-monarchy groups for leading a lavish lifestyle on taxpayers money and living in palatial mansions and castles. 

But their lives are not as easy as many people like to believe.

Some times even the youngest of royals have to abide by harsh rules and etiquettes which common people may found quite upsetting and hard to follow. 

Having brothers and sisters are one of the most precious gifts we have in our lives but Prince William and Kate Middleton's children Prince George and Princess Charlotte are going to be deprived of each other's company on certain occasions. 

Soon, they will no longer be able to travel together for vacations or any other purpose together.

They 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.

Currently the line of succession is:1) Prince William, 2) Prince George, 3) Princess Charlotte, 4) Prince Louis, 5) Prince Harry, 6) Prince Archie (Harry's son), 7) Princess Lilibet (Harry's daughter, 8) Prince Andrew (Charles' younger brother), 9) Princess Beatrice (Andrew's eldest daughter), 10) Sienna Mapelli Mozzi (Beatrice's daughter).
