Nominated MP Godfrey Osotsi now says that Musalia Mudavadi's term as ANC party leader expires next Monday on June 15.
Osotsi has now demanded that the party conduct grassroots polls to elect new officials.
In a press conference on Tuesday, Osotsi who claims to be the founder of the Amani National Congress said the party's constitution provides that leaders hold office for five years after which an election should be done.
The lawmaker also distanced himself from claims to of removing Mudavadi from the party's leadership saying those behind the plot are looking for a scapegoat to take the party to Deputy President William Ruto.
"I do not need to plan to take over the party because I am the founder and I have all the documents," Osotsi said.
According to the nominated MP, the current ANC officials took over in June 2015 and the five years elapses on Monday.
"The best thing is to prepare an election timetable within the party's constitution," Osotsi said.
ODM later on Tuesday has rubbished claims it is plotting to cause leadership turmoil in Musalia Mudavadi's ANC party.
Secretary-General Edwin Sifuna said the Raila Odinga-led party has no reason to stage a coup against Mudavadi who he said is already on a mode of self-destruction.
"We reiterate that the stated policy of ODM party is that of non-interference in internal workings of other political parties," he said.
Sifuna was reacting to claims by Lugari MP Ayub Savula that he was approached by some ODM members to dislodge Mudavadi from the helm of ANC
