Commonwealth leaders unanimously agreed that female heirs to the throne would be equal in the rules of succession. The ruling means that sons and daughters of British monarchs will have equal claim to the throne. The previous rules, that had been in place for over three hundred years, stated that first-born sons had the right to the throne and daughters would only inherit the monarchy had no sons been born or survived. They also agreed to lift the ban that stated British monarchs could not marry Roman Catholics.
