Coalition party leader vs component party

It has been reported today, that a show caused letter might be issued to a coalition party componant (SAPP) due to the motion "Vote no confidence" on the coalition leader.

"Barisan is like a family. They (SAPP) are like a son who wants to remain in the family but cannot get along with the father,"

by Tengku Adnan Yaakob (Barisan secretary-general).

Can we really make comparison or assume the relationship between parties in a coallition as a father-son relationship? Although a son could not betray his father, but a son could definitely speak or make a point that the father is making mistake.

Why SAPP take such brave decision is because they are representing the people (rakyat). Rakyat had clearly make a point that the leader should be changed, but it seems that the leader is refusing go.

In fact I think what SAPP is doing is right on time that may save future havoc in the country. With the bad decisions made by the current administrations, its more likely the rakyat will strikes back sooner or later.
