The line of succession to the British throne is decided by rules on descent, religion, and marriage, not by popularity or politics. As of 2026, the first in line is the King’s eldest son, followed by his siblings and their children, subject to specific historic restrictions. This guide explains how the succession works, who is currently next, and how changes in law and personal events affect the order over time.
How the Line of Succession Is Determined
The rules of succession are set by statute, common law, and tradition, and apply to all parts of the United Kingdom. The core principles include descent from a legitimate marriage, Protestant religion under the Act of Settlement 1701, and prioritisation of older children over younger ones. The Succession to the Crown Act 2013 modernised key parts of the system, removing male-preference primogeniture for those born after 28 October 2011 and removing disqualification for marrying a Catholic, while preserving the monarch’s role as head of the Church of England.
The Core Rules in Practice
- Legitimacy: Only children born to married parents are included unless later legitimised by marriage.
- Religion: Only Protestants in communion with the Church of England can succeed.
- Primogeniture: Among siblings, birth order determines rank; among descendants, the eldest child of the eldest child generally comes first.
These rules mean the line moves mainly through births, marriages, and deaths, with occasional adjustments from changes in law or family choices.
Current Order of the British Line of Succession (Top 10)
The following list reflects the main individuals in line as of 2026, based on publicly confirmed family relationships and the rules above. It covers the first generation likely to be affected in the foreseeable future.
| Position | Name | Relationship to Current King | Key Notes |
|---|---|---|---|
| 1 | Prince William, Prince of Wales | Eldest son | Heir apparent; includes his children in order of birth. |
| 2 | Prince George of Wales | Eldest grandson | Born 2013, first in line after his father. |
| 3 | Princess Charlotte of Wales | Second grandson | Born 2015, precedes her younger brother due to birth order. |
| 4 | Prince Louis of Wales | Third grandson | Born 2018, follows his older sister in line. |
| 5 | Prince Harry, Duke of Sussex | Younger brother | Lines of his children follow after his brother’s family. |
| 6 | Archie Harrison Mountbatten-Windsor | Nephew | Born 2019, ahead of his younger cousin due to birth date. |
| 7 | Lilibet Mountbatten-Windsor | Niece | Born 2021, follows Archie in line. |
| 8 | Prince Andrew, Duke of York | Younger brother | Reinstated in the line of succession after marital status changed. |
| 9 | Princess Beatrice, Mrs Edoardo Mapelli Mozzi | Niece | First daughter of the second son, ahead of her sister due to birth order. |
| 10 | Princess Eugenie, Mrs Jack Brooksbank | Niece | Second daughter of the second son. |
Key Branches of the Line
Beyond the first ten, the line extends through additional siblings, their children, and remarriages. Notable branches include the children of Prince Andrew, the children of the Earl and Countess of Wessex, and the children of the Princess Royal, all ordered by the same principles of descent and birth date.
Special Considerations and Future Changes
- Marriage: Marrying a Catholic no longer removes eligibility, but the monarch remains head of the Church of England.
- Divorce and Remarriage: Legitimacy is determined by whether parents were married at the time of birth; remarriage can create additional eligible branches.
- Waivers and Titles: Heirs may hold titles and undertake duties, and family members may adjust roles without affecting the legal line.
When marriages, births, or legal changes occur, the official list is updated by the Cabinet Office and published on the royal family’s website. Individuals who convert to a non-Protestant religion are disqualified from succession, but public updates are rare and occur only when necessary.
Common Misconceptions About the Line of Succession
Public understanding sometimes confuses ceremonial roles with legal rights, or assumes distant cousins are close in line. In reality, the rules are strict and technical: only descendants of Sophia of Hanover who meet the religion and legitimacy criteria remain eligible. Gender, popularity, or personal choices do not alter the order, though family decisions such as moving abroad or changing surnames may affect public roles.
How to Track Changes to the Line of Succession
The official source for any updates is the royal family’s website and the Cabinet Office registry. Changes are published only when they occur, and historical records remain useful for understanding how the present order emerged. For researchers, genealogists, or simply curious citizens, treating the succession as a legal framework rather than a gossip topic yields the most accurate picture.
Summary of the Current Top Line
In short, the British line of succession flows first to the King’s eldest son and his children, then to his younger brother and his family, followed by other branches descended from Queen Victoria and King George V. Birth order, Protestant faith, and legitimacy under English law remain the decisive factors. Staying informed through official channels ensures access to the most reliable and up-to-date information.
