With so much money floating from corruption, Jubilee thieves headed to Tanzania. They "invested" in mining and many other businesses. They registered shell companies in Mauritius, etc which they used to rob Tanzania.
In the last elections, they wanted Lowassa to win so he could grant them more freedom. In fact they had three to four candidates they had bought. One refused but gathered enough informations about the specific interests he was supposed to "protect"
That is when CCM discovered the "Kenyan" plot and decided to act. Magufuli won the nominations and Lowassa stunned at his defeat went to the Opposition. Kenyan money poured in to his campaign to no avail. Magufuli won.
He then set about dismantling the activities of the Kenyan cartels in his country.
