Within the same period, Duke also paid tax to the tune of N400,000.
The former governor of Cross River State claimed to have made the money from business.
Duke stated in his form that he had never been indicted for fraud by a judicial panel even as he said he had never been involved in certificate forgery.
The former governor attached his school certificate from the West African Examination Council indicating that he passed all subjects in 1977. However, mathematics was not listed among the subjects he sat for.
Duke graduated from Ahmadu Bello University with a Second Class (lower division) in law.
Meanwhile, the United Nations Special Representative of the Secretary-General for West Africa and the Sahel, and Head of UNOWAS, Mohamed Ibn Chambas, says a UN delegation has visited President Muhammadu Buhari and security agencies.

Chambas said this when he paid a courtesy visit to INEC in Abuja on Tuesday.
He said they would be visiting opposition candidates in the coming days.
The UN official said that the rest of the world was looking forward towards peaceful elections in Nigeria.
“We are looking forward towards a peaceful election in Nigeria. All the member states are looking towards Nigeria,” he said.
