Gatanga MP Joseph Nduati has asked the Opposition to permanently call off plans to swear in its leader Raila Odinga.
He said the issue has caused a lot of anxiety as Kenyans are worried that there will be more violent protests.
Raila was to be sworn in on Tuesday as the people's president but postponed the event.
Nduati said the government should take stern action against NASA if it insists on going ahead with the event.
He said the country has already election its president and there is no chance for Raila to be inaugurated.
The MP also said the Opposition should forget the possibility of holding talks with the Jubilee administration on election as "it is time to concentrate on development".
"Any dialogue that may be held between the government and the opposition should be on development and not on whether we should go back to the ballot. Elections are over and Kenyans want services,” he added.
The MP was speaking during Jamhuri day celebrations in Jogoo Kimakia grounds.
"As a member of the Jubilee party, I', asking President Uhuru Kenyatta to hit the ground running and embark on fulfilling the development agenda that he promised to Kenyans," he said.
On Sunday, NASA coprincipals Musalia Mudavadi and Moses Wetang'ula said they have moved the swearing in ceremony.
Musalia said although their supporters will be disappointed, the coalition will continue to push for change.
He noted that the Opposition is not interested in power-sharing as the Jubilee administration is "illegitimate and dictatorial".
Any dialogue, Musalia said, will have to be on electoral justice and not on power sharing.
Uhuru warned against using unconstitutional means while airing grievances.
He also said he is ready to work with leaders across the political divide, but said those subverting the constitution will be dealt with accordingly.
Attorney General Githu Muigai had warned Raila against being sworn in, saying it is an act of high treason.
