No, Keter has been at the "trough" longer... na ndiye ameiba zaidi. Remember he was Ass. Minister appointed by Raila and cried when he was sacked! You are obviously aware that Keter back home in Kericho bought huge tracts of land, built a huge mansion which you can see from the highway and is trying to compete with Chirchir to also set up a Tea factory.
Njoroge was long time at KPLC as Regional Chief Engineer to MD; kula'ed a couple here and there but stole big (in spades) when he became PS.
The PS especially has been on this for ages. He is another Samwel Gicheru.
Both Minister and PS moved.... very corrupt fellows. Should have been summarily fired!
