He admitted his kids went to private schools while he try to make others go through the public system hoping that his clans can rule forever.
When his son failed to make into the inner circle, he started to attack the very system he created.
When he failed to get his son one of the 3 VP post last year, it just showed that his once powerful influence had diminished.
Holding a VP post is like getting an onward passport to the premier route, but unfortunately his son may miss this chance while his is still alive.
He thought he can still weld the power to displace the PM as he wishes like he what did to the former one but this one has a much stronger power base than he thought.
So, now all these caustic remarks aiming at the PM all you see now prelude to perhaps some showdown very soon.
