The 36 States Governors of the federation on Tuesday agreed to fully implement the #18,000 minimum wage to their workers.
However, the governors also called on the President GEJ to immediately remove the subsidy on petroleum.

If they can think of removal of subsidy on petroleum.what about reduction of political office holders' salaries & allowances?

I agree with the poster, the states should fund the salary increase by substantially slashing the bogus allowance of the myriad of political office holders and the numerous assistants, and most especially the so called security votes kust like Rochas did to finance his free education programme.
The funds are there, the guys who are supposed to distribute it are busy "helping" themselves.
