When Jimmy takes up his post as the new Consul at the start of the year he will have to give up his current role of Minister of the Interior. Ronald has indicated he wants to take over this role (and thus it will happen). MBH may have thought about taking on that role himself when he stands down as Consul.
Ronald's current job of Minister of Culture will be available though it is possible GBH takes the role over. Officially GBH is Minister of DDS Affairs but he doesn't really have anything to do. Pircasa, as liaison officer, takes one for the team.
