According to ‘Anidda’, they want the implementation of the recommendations by the Ruwan Wijewardena-led committee.
They want the matter to be settled amicably, but warned they had no other option but to sit in the opposition if the leader did not listen to the majority voice in the party.
Around 30 MPs are involved in discussions, and at least 20 will resort to the extreme measure, according to the newspaper.
Problems have worsened for the UNP due to the cold war now brewing between the party leadership and the faction led by deputy leader Ravi Karunanayake.
The Karunanayake faction is opposed to the appointment of Mangala Samaraweera as a deputy leader.
Karunanayake told Sri Lanka Mirror that he was not concerned by trivialities, but was keeping a watch on what the leadership would do with regard rebellious factions.
