over throw

Let's consider if the people struggle and the demonstrations are by a fraction of the population, then there is no reason for the past president to step-down or the prime Minister to step-down at the first place. Which indicates there is a considerable population behind the entire demonstration and it created sufficient enough pressure among the ruling party and the parliament to act on the necessary reforms. 

As far as the development on the people demonstrations it's not complete yet 

So the key things the political setup need to address is the fulfillment of the basic demands and requirements by the demonstration as well as to facilitate the long pending reforms for the entire political setup to stabilize the political situation. Most of the age old grandfather's of the parliament may have to retire from politics and open the door to young blood, having said that this would need an immediate election 

Next is main issue with present administration and the parliament setup is such that people have no confidence and distrust on any of the steps taken. This visious chain has to be broken, one is by being open and taking necessary actions against all forms of corruption as well as taking action at correct the issues facing by the public 

Finally the public shall be relived from the burden and shall not insert further more stress 

These are not my own personal views but what I summarized based on the some discussions and lectures
