Article 86 provides that, in the event that there are no descendants of King Leopold I, the King can name a successor with the consent of both Chambers of the Federal Parliament. This consent cannot be given unless a quorum of at least two-thirds of its members is present and at least two-thirds of the votes cast are in the affirmative. In case no successor has been appointed in this manner, the throne is vacant. Article 95 stipulates that, in the event that the throne is vacant, the United Chambers meet to provisionally provide for the regency. Subsequently, a federal election must take place and the newly elected Federal Parliament must meet within two months to permanently fill the vacancy.
