Narc Kenya leader Martha Karua now says that their being in the Opposition is not based on Azimio leader Raila Odinga's presence or absence.
Speaking on Thursday, Karua said whether Raila gets the African Union Commission chairmanship or not, her party will remain the voice of the people.
She insisted that the opposition role is a job they take seriously.
"Whether or not our brother Raila goes to AU, and we wish him well, the position doesn't change. He remains here we still remain a voice, he goes we still play our role. Our being in the opposition is not predicated in the presence or absence of our brother, it is a duty we take up seriously," Karua said.
She added that they take their civil responsibility seriously because they are good citizens.
The Narc Kenya leader said her Party will always stand up for what is right and will work with like-minded parties in playing the opposition role.
"We do not need any title and we have always tried to be good citizens who take up their civil responsibility in this country. This party will continue to stand up for what is right. We are not a party in government, we are the Opposition and we are used to being in the opposition trenches for the longest.
"You can expect that we'll continue to do so and our colleagues who wish to do so will collaborate with them but I speak for Narc Kenya and this is our promise to Kenyans," Karua insisted.
Her remarks come even as the Opposition stands divided over the move by President William Ruto to work with ODM leaders in his Cabinet.
The move prompted Karua's party to announce that it was exiting the Azimio coalition.
