Secretary to the President, Nana Bediatuo Asante and Political Assistant to the President, Francis Asenso-Boakye, were part of the few people who attended the swearing in.
The President had on Friday sworn in 12 Ministers out of the 13 following what has been described as a torturous approval from Parliament.
Minority Members of Parliament (MPs) on the Appointments Committee had earlier torpedoed efforts to approve Senior Minister, Yaw Osafo Maafo and Energy Minister, Boakye Agyarko.
The Majority New Patriotic Party (NPP) MPs were unable to build consensus, but after bouts of allegations and counter allegations about an attempted bribery, the situation was resolved.
All 13 of them were approved by a unanimous consensus by the legislators and within minutes, President Akufo-Addo administered the Minister's Oath to them.
Shirley Botchway was out of the country when the ceremony was held. She went ahead of the President to Ethiopia to make preparation for his arrival for the African Union (AU) Summit.
The President disclosed at the Accra ceremony that he would swear her in when he arrives in Ethiopia.
Fulfilling his promise, the President charged the Minister to discharge her duties to the satisfaction of the country without fear or favour.
