He made this known in a goodwill message at the Peoples Democratic Party (PDP) National Convention in Abuja on Saturday.
Aliyu, who spoke on behalf of former PDP governors, said come 2019, the party would ensure that agriculture was given the kind of subsidy required.
“We will ensure that agriculture becomes commercialised and mechanised. Naira has depreciated. Importing any food in Nigeria will be a waste because you will not make any profit.
“Our importers are not importing food and therefore we must understand that it was not a deliberate plan; it was a plan by devaluation.”
Aliyu commended the National Caretaker Committee Chairman Ahmed Makarfi for holding forth during the party’s trying moments.
“We will live more united, stronger and ready to take over in 2019, PDP governors have done beautifully well and there is no alternative to the PDP,” he said.
