The closed session of the CPN-UML's 11th general convention is underway at Bhrikuti Mandap in Kathmandu.
The closed session, which began after 3 p.m. on Sunday, was first addressed by Chairman KP Sharma Oli.
He was followed by Senior Vice-chairman Ishwar Pokharel, who presented a separate concept paper.
A secretariat meeting held on Friday had agreed to allow Pokharel to present his concept paper during his turn.
A few days ago, Pokharel had submitted his concept paper to General Secretary Shankar Pokharel at the party's central office.
The senior vice-chairman had said that the issues raised by him should also be included in the document to be presented the party at the closed session.
