United Cabinet of Kilmark–Killarney

The United Cabinet is the common executive government of Kilmark–Killarney, a dual monarchy in maritime Western Europe which occupies the island of Atlantica Alba and its associated islands, consisting of the Kingdom of Kilmark and Kingdom of Killarney. Formed as a personal union in 1447 when King Andrew of Killarney inherited the throne of Kilmark through his paternal great-uncle following the death of the childless Queen of Kilmark Mary II, in 1880 the dual monarchy was transformed into a real union when King Andrew IX directed the Parliament of Kilmark and Parliament of Killarney to simultaneously pass the Realms Defence Act, which unified the armies and navies of the two kingdoms into a single army and navy, abolishing the two respective war and naval ministries and replacing them with a new single defence ministry, also establishing a new cabinet directly answerable to the monarch which would oversee the new united defence ministry. The act also abolished the two kingdoms' respective foreign ministries, which were replaced with a new common foreign ministry also answerable to the new cabinet.

As of 2020, the United Cabinet oversees only five distinct ministries, none of which have counterparts answerable to the cabinets of the two kingdoms, which continue to handle the great majority of national government responsibilities. These five ministries are: the Ministry of Defence, Ministry of Foreign Affairs, Ministry of Finance, Ministry of Customs and Immigration and Ministry of Air Transport.

While the cabinets of the two kingdoms are each chaired by a prime minister (head of government), who is appointed by the respective kingdom's democratically elected parliament, the United Cabinet is chaired by the Governor-General, who is directly appointed by the monarch of Kilmark–Killarney and who in turn nominates cabinet ministers to be formally appointed by the monarch. As such, while the national governments of the two kingdoms are democratically chosen, the United Cabinet is not, essentially rendering the monarch a de facto absolutist ruler as far as concerns the responsibilities of the United Cabinet, especially considering the absence of a united parliament or constitution. Nevertheless, according to custom, the Governor-General, while officially appointed by the monarch, is always nominated by both the Prime Minister of Kilmark and the Prime Minister of Killarney, meaning the United Cabinet is somewhat democratically formed, though there is no process by which the Governor-General may be removed from office other than by royal decree.
