Line of succession: Will Baby Sussex be a Prince? Where will the new royal baby be in line for the throne?

The Duke and Duchess of Sussex have announced the arrival of their baby son. Though they are yet to announce the name of their little boy (Prince Harry said they were still thinking about names) he said they were "absolutely thrilled" and thanked well wishers.

With Prince Harry sixth in line to the throne (after his nephew Prince Louis), here's how the new arrival will shake up the line of succession.

What is the royal line of succession now?

While previously male siblings in the royal family took precedence over their sisters, a 2013 law called The Succession to the Crown Act decreed that "it ends the system of male preference under which a younger son displaces an elder daughter in the line of succession". The law also allowed anyone who marries a Roman Catholic to keep their place in the line of succession, as well as repealing something called the Royal Marriages Act 1772.

The law only applied to those born after October 2011, but it’s already had an impact. If the act hadn’t come into place, Princess Charlotte would have had to forfeit her place in line to her younger brother Prince Louis when he was born last year.

Here is the line of succession:

1. Prince of Wales (Prince Charles)

2. Duke of Cambridge (Prince William)

3. Prince George of Cambridge

4. Princess Charlotte of Cambridge

5. Prince Louis of Cambridge

6. Duke of Sussex (Prince Harry)

7. Baby Sussex

8. Duke of York (Prince Andrew)

9. Princess Beatrice of York

10. Princess Eugenie of York

11. The Earl of Wessex (Prince Edward)

12. Viscount Severn (Philip Theo Mountbatten-Windsor)

13. The Lady Louise Mountbatten-Windsor

14. The Princess Royal (Princess Anne)

15. Mr. Peter Phillips

16. Miss Savannah Phillips

17. Miss Isla Phillips

18. Mrs. Michael Tindall​

Where will the royal baby be in line for the throne?

Princess Beatrice, Princess Eugenie and their father Prince Andrew, are now booted one rung down after the arrival of Meghan Markle and Prince Harry’s child. The new Baby Sussex falls seventh in the line of succession, after his father Prince Harry, a spot which Prince Andrew currently holds.

Prince Andrew will now fall into eighth place, with Princess Beatrice as ninth and Princess Eugenie tenth.

How will Meghan Markle’s baby related to the Queen?

Meghan Markle’s baby is the newest great-grandson of Queen Elizabeth and Prince Philip, through Meghan’s husband Prince Harry. Prince Harry’s father Prince Charles and stepmother Camilla Parker-Bowles are the baby's grandparents on the royal side, while Meghan Markle’s mother Doria Ragland and estranged father Thomas Markle Sr. are maternal grandparents.

Kate Middleton and Prince William are aunt and uncle to the child, meaning their children Prince George, Princess Charlotte and Prince Louis are all cousins.

Meghan Markle and Prince Harry’s child is the eighth of Queen Elizabeth and Prince Philip’s great grandchildren, who also include the Cambridges’ three children, Zara and Mike Tindall’s two daughters and Peter Philips’ two daughters Savannah and Isla.

Will Baby Sussex be a Prince?

Even though Prince William and Kate Middleton’s children all have a prince or princess title to their name, it doesn’t seem likely Prince Harry and Meghan Markle’s son will. This is because King George V introduced a stipulation that only children of the King or Queen, children of the King or Queen’s sons and only the eldest living son of the eldest living son of the Prince of Wales were eligible for titles.

King George V said, “the grandchildren of the sons of any such Sovereign in the direct male line (save only the eldest living son of the eldest son of the Prince of Wales) shall have and enjoy in all occasions the style and title enjoyed by the children of Dukes of these Our Realms”.

Instead, Prince Harry and Meghan Markle’s children will have different titles. Their new son could take over one of Prince Harry’s titles, the Earl of Dumbarton.
