Princess Charlotte could receive a new title when her father, Prince William, becomes king.

The Duke of Cambridge, 40, is currently second in line to the throne, meaning it is very likely he will become the reigning king during his lifetime.

As a new monarch ascends the throne and the line of succession changes, some members of the royal family may receive a new title.

As for 7-year-old Princess Charlotte, the young royal could be given the title of The Princess Royal, which is traditionally bestowed upon the eldest daughter of the sovereign.

It would make Princess Charlotte the eighth Princess Royal in British royal history.

The title is currently held by Anne, the Queen’s eldest daughter, who received it in 1987.

According to stringent royal protocol, the title is held for life, even if the holder outlives the monarch, meaning only one person can hold the title at any one time.

Under these rules, Princess Charlotte will only be eligible for the title if Princess Anne passes away and Prince William becomes king.

As Princess Charlotte and her siblings George, 8, and Louis, 4, have gotten older, they have been taking part in more royal public engagements, most recently stealing the show at the Queen’s platinum jubilee celebrations.
