In Conakry, he drafted, jointly with Félix-Roland Moumié and Ernest Ouandié, a political minimum platform for Cameroon. Mbida came back to Cameroon in 1960 and he regained in a very short time period a national political audience that thirteen months of exile in Conakry (Guinea) had somewhat withered. On 10 April 1960, he was elected as deputy in his district. He obtained 23,770 votes against 0. Following these elections, the audience and even the popularity of Mbida were well established in Cameroon with a predominance in the region of Nyong and Sanaga. Nevertheless, the final battle that he would deliver against the Ahidjo's Government, the battle against the single-party state, the one-party system, would sound the knell of his political life.
