How the British Line of Succession Works
The British line of succession is governed by a mix of common law, statutory rules, and recent changes, including the Succession to the Crown Act 2013. Under the current rules, the crown passes to the eldest child of the monarch, regardless of gender, removing the old male primogeniture rule for those born after 28 October 2011. The system also requires the monarch to be in communion with the Church of England, as set out in the Act of Settlement 1701 and the Bill of Rights 1689. The line is counted from the descendants of Sophia of Hanover, a granddaughter of King James I, as specified in the Act of Settlement 1701, which is why Roman Catholics and their descendants are excluded. The Succession to the Crown Act 2013 also ended the disqualification for marrying a Roman Catholic, though the monarch themselves must still be Protestant. These rules apply across the realms, with the British line serving as the core list for the United Kingdom and other Commonwealth realms that share the same sovereign.
The order is determined by birth order, legitimacy, and religion, with legitimate children taking precedence over illegitimate children under the current legal framework. The list is updated by the Privy Council and published officially by the Cabinet Office, with the most recent version reflecting births, deaths, marriages, and changes in religion. The first in line is always the eldest child of the sovereign, followed by that child's descendants in order of birth, then siblings and their descendants, and so on. The rules apply to those born after the relevant changes take effect, meaning older members of the family who married Catholics before the 2013 reform were not removed from the line. The official line is maintained by the government and can be consulted through official publications and trusted sources on constitutional law and monarchy succession.
Current Heirs in the Line of Succession
As of the latest official updates, the first in line is Prince William, Prince of Wales, the elder son of King Charles III. He is followed by his children in order of birth, starting with Prince George of Wales, then Princess Charlotte of Wales, and Prince Louis of Wales. Next in line after William is his younger brother, Prince Harry, Duke of Sussex, and then Harry's children, Prince Archie of Sussex and Princess Lilibet of Sussex. The list continues through the siblings and descendants of King Charles III, including the children of Princess Anne, the Princess Royal, and the descendants of the late Queen Elizabeth II's sister, Princess Margaret. The order reflects the shift to absolute primogeniture for those born after 28 October 2011, meaning gender no longer determines precedence among siblings.
The second generation of heirs now includes several young children whose positions are secure under the current rules, with Prince George first among them, followed by Princess Charlotte and Prince Louis. The line also includes the descendants of the Duke of York, the Duke of Edinburgh, and other members of the royal family who remain in the official order. Changes to the line occur mainly through births, marriages that meet the religious requirements, and deaths, with the government updating the list accordingly. The official line is a matter of public record and is used for ceremonial, constitutional, and protocol purposes across the United Kingdom and the Commonwealth realms.

Key Rules and Constitutional Context
The British line of succession is shaped by several key rules, including the requirement that the sovereign must be Protestant and in communion with the Church of England. The Act of Settlement 1701 and the Bill of Rights 1689 set the basic framework, while the Succession to the Crown Act 2013 modernized the rules by introducing absolute primogeniture for those born after 28 October
