Princess Charlene, consort of Prince Albert II of Monaco is expecting twins by the end of the year. I discussed the succession in Monaco with Eun Kim at today.com. In contrast to most other European ruling houses, Monaco has not introduced gender neutral succession policies. If the twins are a boy and girl, the boy will be heir regardless of which twin is born first. The most recent succession reforms in Monaco, passed in 2002, allowed Albert’s siblings and their children to succeed in the event that Albert remained childless. Albert’s sister. Princess Caroline, is the current heir until the arrival of the twins.
