It is likely that the no-nonsense disciplinary committee will find him guilty of some charge like violating the party's code of conduct or behaving in a manner unbecoming of a deputy president or something like that and punish him.
His punishment will come in the form of either a dismissal or a suspension.
Chances are the leaders of the party will not take the risk of going all the way and sack him. Therefore the deputy president will most likely be suspended for a year or two.
That action will spark off Act One Scene Three or Act Two Scene One or whatever...
What will happen next? Will supporters of the deputy president make a move for an EGM? Will there be a motion of no confidence against the party president?
