Charles III automatically became the new King of Britain following the death of his mother, Queen Elizabeth II, at the age of 96, on Thursday. So who is next after Charles? He waited 70 years to become king, making him the longest-serving heir in British history; he is the eldest of four children born to the Queen and her late husband, Prince Philip. When his mother ascended the throne at the age of 25, he became heir apparent at the age of 3. In the event of his death, the next in line is Charles's eldest son, William (40 years old), known as the Duke of Cambridge. With the death of the queen, a new title is added to William, which is Prince of Wales (previously held by Charles before ascending to the throne) / Duke of Cornwall.
Next in the line of succession is William's eldest child, Prince George, who is 9 years old. Then comes Princess Charlotte, the Princess of Cambridge, born on May 2, 2015, the second child of Prince William, Duke of Cambridge, and his wife Catherine. Following her is Prince Louis, the Prince of Cambridge, born on April 23, 2018, the third child of Prince William. It is expected that the names of the three princes will change after their father ascends the throne.
Fifth in the line of succession is Harry, despite his controversial decision to step back from royal duties and move to the United States with his wife Meghan, where they live with their children Archie and Lilibet. After him are his children, Archie, who is 3 years old, and Lilibet, who is one year old. Thus, half of the royal family members awaiting their turn for the throne are children. However, regulations state that anyone of any age can become king, but children are not allowed to perform royal duties until they reach the age of 18. Therefore, if it comes to George, he would serve as a "symbolic king" only, accompanied by a prince or princess as a regent over the throne who is over 18 years old.
