Five of the assembly members were absent.
Madam Dora Tamea, the Jaman South District Chief Executive said she was disappointed with the assembly members, noting that, the house failure to elect a PM was a big blow to the assembly.
She said until the assembly members buried their personal interest, development would not progress in the district.
Madam Tamea emphasized that the assembly members had not only disappointed their constituents, but failed the entire district.
She advised the assembly members to unite and contribute meaningfully to the development of the district.
Mr Kwame Siegfried Addo, the Jaman South District Coordinating Director, explained a circular received from the Ministry of Local Government and Rural Development mandates the house to elect a PM by simple majority to preside at meetings upon the assembly’s failure to elect a substantive PM.
