Mr Apreku Agyepong is the second UG student to have won the category at the tournament after Jeremiah Sekyi in 2019.
Participants of the Public Speaking category of the tournament had to undergo two preliminary rounds and a semi-final round to reach the final.
The final challenge required participants to defend an imaginary juvenile who had committed a crime that could necessitate him or her being tried as an adult.
Kweku Agyepong was a member of the 10 member delegation UG presented for the tournament this year.
