The meeting is ostensibly to fashion out a common position as the legislators elect their leaders for the ninth assembly.
It was not clear whether the main opposition party will be presenting candidates within the party or would side with the candidates being floated by the ruling All Progressive Congress (APC).
The meeting is also being attended by immediate past Speaker of the House of Representatives, Yakubu Dogara, who has already denied interest in the speakership position.
The meeting was yet to start at the time of this report.
