Speaker of the house of representatives, Yakubu Dogara, has reportedly picked the Peoples Democratic Party (PDP) nomination form to return to the lower legislative chamber.
TheCable reported that Dogara was said to have picked the form, and that of expression of interest, on Wednesday.
The speaker is expected to formally announce his defection when the lawmakers return from recess later this month.
Dogara was among those rumoured to have been plotting his defection when about 37 members of the house of representatives left the ruling party.
The speaker has not been seen in recent meetings of the party.
