On Saturday, Mwingi West MP Charles Nguna vowed to resign if it is proved that he holds dual citizenship.
The Wiper Democratic Movement politician was responding to allegations made by activist Okiya Omtatah, who had asked the Ethics and Anti-Corruption Commission (EACC) to investigate nine other MPs over dual nationality.
Mr Nguna denied being a Greek citizen, stating that his parents being Greek citizens does not necessarily qualify him as one too.
"This is baseless propaganda engineered by my political opponents after I defended diplomatic nominee Ms Mwende Mwinzi, both on the floor of the House and outside," he said.
Mr Nguna clarified that he has worked with international companies and lived outside Kenya, but never sought dual citizenship.
"I've lived outside Kenya, but I never sought dual citizenship. The fact that I visit my parents in Greece quiet often doesn't mean I am a citizen. I want EACC to hasten their investigations into the matter," he said.
Mr Nguna's statement comes after the issue of dual citizenship was raised during the vetting of Ms Mwinzi as the envoy to Seoul, South Korea.
Ms Mwinzi had moved to the High Court last month seeking to have the National Assembly stopped from forcing her to renounce her US citizenship before taking up the role.
On Thursday, EACC Chief Executive Officer Twalib Mbarak said investigations into the matter are ongoing.
