What would you call an absolute monarchy (or, even better, a Consitutional Monarchy, since it doesn't have to worry about militancy hits a lot for changing parties) who decided to appoint the Communist Party into office in order to take advantage of the Communist's Planned Economy?
If they go whole hog with the Communist economic model, I'd just call it a Communist state.
Or would you call Cambodia a monarchy for the few months that Sihanouk was in power in the middle 1970's in alliance with Red Khmers? :rofl:
In the end, it's meaningless semantics.
EDIT: I have to say that Cambodia is a supremely useful examples in these Vicky II discussions about how weird things can really get in the real world...not the first time I'm using it.
