Likoni MP Mishi Mboko has called for unity among NASA principals Raila Odinga, Kalonzo Musyoka, Musalia Mudavadi and Moses Wetangula.
Speaking in Likoni Town on Saturday, Mboko said that the four NASA top leaders have no option but to remain united.
She said that it will be embarrassing to NASA supporters if the coalition breaks without fulfilling its core agenda.
Mboko said that the country's future is pegged on NASA leaders, stating that they must fulfill the promise of fighting for electoral reforms, justice, an end to police brutality and ensure adherence to rule of law.
The ODM MP said that Kenyans have hope in NASA, adding that any betrayal among the top leaders will be a big disappointment to the country.
"Our leaders in NASA have no option but to remain united and steer the electoral reforms and justice agenda forward," she said.
Mboko said that the country will remain in a delicate path if NASA abandons the reforms agenda.
She said that families that lost their loved ones in regards to last year's election are still crying for justice.
The MP called on NASA leaders to iron out any differences that could be threatening their unity.
She also urged NASA politicians to remain committed to the fight against electoral injustices.
Mboko said that credibility of future elections can only be guaranteed if institutional reforms and rule of law is upheld.
There have been claims of disunity among NASA top leaders that is threatening unity of the coalition.
NASA principals have, however, downplayed claims of cracks in the coalition assuring supporters that they are committed on their push for electoral reforms and justice
