Camilla ranks higher than Kate.
But do Camilla and Kate rank higher than Anne as things stand?

The order of precedence accorded to women of the royal family differs depending on whether or not they are accompanied by a husband who is of higher precedence by birthright. Thus two tables are given below: the first outlines the order of precedence for women of the royal family when unaccompanied by a more senior ranking spouse. The second shows the order of precedence when female members of the royal family are joined by their spouses of the blood Royal. This is done because when unaccompanied, blood relations of the sovereign are always accorded higher precedence than those who are married in. For example, when not accompanied by the Prince of Wales, Camilla, Duchess of Cornwall, ranks after Princess Alexandra, The Honorable Lady Ogilvy; when with him, she ranks above all women other than the reigning sovereign and any queens dowager. The same goes for spouses of the Queen’s grandsons and their positioning with the Queen’s granddaughters. For example, as a Princess of the blood Royal, Princess Beatrice of York outranks Catherine, Duchess of Cambridge if Catherine is unaccompanied by Prince William, Duke of Cambridge.
