2016 Parliamentary election Nitiwul won the 2016 Parliamentary elections for his constituency by defeating the
National Democratic Congress candidate
Dr Joseph Mamboah Rockson. Prior to the elections Nitiwul had announced that he would win due to the fact that his opponent was not a native of the constituency and was not abreast with what was happening in the constituency; he also cited the numerous developmental projects he had undertaken. His opponent opined that Nitiwul had served for far too long and believed the constituents needed a new face.
Developmental projects Nitiwul has embarked on developmental projects in Bimbilla to better the lot of his constituents. He had 69
boreholes drilled in various communities in his constituencies, and got the
Northern Electricity Distribution Company to extend electricity to 16 communities. He built two clinics, twelve roads projects, and classroom blocks. ==Minister of Defence==
