Najib, he is allegedly involved in corruption vis a-vis the so-called RM2.6 bil donation and gross mismanagement of 1MDB that may have led to, amongst other things, money laundering.

In so far as TSMY is concerned, as mentioned by Mustapha Ong, he is one of the most senior leaders in UMNO. Many in UMNO now may not have been born yet, when he first assumed his govt post. He is an UMNO diehard. Not until the case of corruption and the 1MDB scandal surface, he has been fully supportive of Najib on all matters, issues and policies both that of the party and the govt.

So, the question of him quitting does not arise at all. The most honorable thing for him to do is to stay put and pursuenot crack our head to know the reasons why.

Another species worth highlighting is Teuku Adnan, UMNO Sec.Gen. He appears to have been given the carte blanche, to say anything and to do anything, the latest threatening to suspend 7 UMNO members/officials whom he could'nt tolerate anymore allegedly for bringing the party into disrepute. Perhaps one of the victims will be TDM.

As you may recall, at the time when he was in political wilderness, it was TDM who made him UMNO's Ex. Sec. It was TDM who recommended him for the senatorship. It was TDM who appointed him as Dep. Minister.
