Succession
The queen has given her approval for Parliament to consider a law that would give royal daughters the right to inherit the throne before their younger brothers. Under current law, Prince Andrew and Prince Edward rank ahead of their older sister, Princess Anne, in the line of sucession. If the law changes, Anne will be fourth in line to the throne. Prince Charles, as the queen's eldest child, will remain heir to the throne.
