Despite having an older sister in Princess Anne, Prince Andrew, Prince Charles’ younger brother, was second in line to the British throne until he had children.

Why is Princess Anne not in line for the throne?

Despite the fact that Anne is Queen Elizabeth’s and Prince Philip’s second child, her younger brothers, Prince Andrew and Prince Edward, surpassed her in the line of succession.

(This is something that The Crown mentions in the fourth season.) Despite having a younger brother in Prince Louis, Princess Charlotte kept her place behind big brother Prince George.

If their parents had a younger son, like Princess Anne’s parents did, older sisters in the royal family would be shifted down a slot in the order of succession until 2013.

The Succession to the Crown Act 2013, which was passed in 2013, specifies who will be the next king or queen of the United Kingdom, regardless of gender.

While Kate Middleton and Prince William were expecting their first child, the legislation was passed.

It applies to all royals born after October 28, 2011, and removes the disqualification imposed on those who married a Roman Catholic.
