Dr Dominic Akuritinga Ayine, former Deputy Attorney General and MP for Bolgatanga East constituency, made this announcement following a conditional boycott declared by the NPP, led by Alexander Afenyo-Markin.
The NPP's decision to boycott was triggered by Speaker Alban Bagbin's declaration of four vacant seats in Parliament, three of which belonged to the NPP and one to the NDC.
As a result, the NDC now asserts its position as the majority party in Parliament.
Dr Ayine remarked that a "new regime" would be established when sittings resume, asserting the NDC's commitment to acting on behalf of the electorate.
