The incumbent MP for Kwesimintsim in Western region Joe Baidoe-Ansah has lost the NPP’s parliamentary primaries in the constituency.
He lost to his only contender Joe Mensah in the keenly contested polls held on Tuesday.
The MP who was seeking a fifth term in parliament garnered 122 votes as against the victor's 187.
The primary in the constituency was delayed after the executives in the constituency initially disqualified Joe Mensah from contesting.
A High court subsequently ruled that Mr. Mensah was qualified to contest the race.
