I was running a check on when this subsidy that has become a curse was introduced but stumbled on what appears like Buhari is contradicting himself.

When we came into power in December 1983, we were approached by the world power at some stage to devalue the naira, remove petroleum subsidy and remove subsidy on flour, but we refused," he said.
He explained that "the issue was that if we get plenty of naira, what are we going to do with it? We even stopped farming and the only thing we get money from them was oil and that was being paid in dollars."

He said "if you have excess of groundnut, cocoa, cotton or palm oil, you sell it in foreign exchange. If you devalue the currency, the naira will be affected and Nigerians will not get value for their goods and services."

With the above quote why is Buhari now telling us that he doesn't know what subsidy means as reported on Sunday? Is he double speaking?
