What is exactly the beef between a Luo Nyanza MP and a Principal Secretary in a key ministry?

The first time MP was on Tuesday overheard telling a colleague how he confronted the PS, whose name was adversely mentioned in a major scandal that was subject of investigations by Parliament and other investigative agencies – over an alleged tribalism in discharging his duties.

The MP said he told the man that he would not survive “the handshake” if he did not change his way of operations.
