In the 2011 Perth Agreement, the heads of government of all 16 Commonwealth realms agreed to take the appropriate steps in their respective countries to adopt absolute primogeniture, end the exclusion of people married to Roman Catholics, and limit the requirement for those in line to seek the permission of the monarch to marry. The Succession to the Crown Act 2013 in Britain and other acts in some other Commonwealth realms have been passed, but the provisions for altering the succession have not yet come into force in any country.
The list below of persons in line of succession to the present Queen is limited to the Queen's descendants (numbered 1 to 16) and others in the nearest collateral lines, namely, the other eligible descendants of the sons of George V (numbered 17 to 51). Persons shown who are not in line to the throne are in italics.
No official, complete version of the line of succession is currently maintained. Any person's actual position in the line of succession may change as a result of events such as births and deaths.
MC These people were excluded through marriage to a Roman Catholic. This exclusion is repealed under s. 2(2) of the Succession to the Crown Act 2013, restoring them to the line of succession once it comes into effect.

1952 Succession as published on the accession of Queen Elizabeth II in 1952
The line of succession continues with the eligible descendants of Mary, Princess Royal and Countess of Harewood, only daughter of George V, followed by the other eligible descendants of Edward VII and earlier British monarchs, back to George I (the line is limited to Sophia of Hanover's descendants, of whom all alive today are also George I's descendants). The last person in line (which runs into thousands) was reported in 2011 to be Karin Vogel (born 1973) from Rostock, Germany.
^Governments of the Commonwealth realms have acknowledged that a change in the line of succession in respect of any one of the realms is made in accordance with the constitutional law of that realm.
^The Legitimacy Act 1926, 10 (1) says, "Nothing in this Act shall affect the Succession to any dignity or title of honour or render any person capable of succeeding to or transmitting a right to succeed to any such dignity or title." The Legitimacy Act 1959, 6 (4) says, "It is hereby declared that nothing in this Act affects the Succession to the Throne."
^ abcdThe governments of the Commonwealth realms have agreed to changes to the line of succession that would see Tane Lewis and Rufus Gilman switch places with their elder sisters Senna and Lyla respectively. Since Tane and Rufus were born after 28 October 2011 (the date of the agreement), they would lose their male preference under the changes.
^Albert and Leopold Windsor are listed on The Official Website of the British Monarchy and in the 2013 edition of Whitaker's Almanack as following Estella Taylor (b 2004), not following Lady Amelia Windsor. As they were baptised as Catholics, they are not listed in Debrett's or editions of Whitaker's earlier than 2012.
