What's the distinction between "resign" and "merely stepped aside for an unspecified amount of time and will continue to serve as the Chairman of the Progressive Party."
The last time an executive at my company took a "sabbatical" they never came back. It honestly sounds like your PM is trying to resign without using the word.
the main one: right before new disclosure, regulation, and taxation laws came into effect, he sold 50% ownership stake in his holdings of the shell corp to his wife for $1, so that he would not be subject to the new laws.
in general: one does not have to literally break the law to be asked to resign by your citizens. that is not, and should not be, the standards to which we hold our leaders.
