Those who obtained membership with the Sri Lanka Podujana Party can witness the SLFP convention from the giant screen outside the Sugathadasa Indoor Stadium, UPFA General Secretary Mahinda Amaraweera said.
Speaking to the media, Amaraweera said no invitations would be sent to the MPs who joined other parties requesting them to attend the 69th anniversary celebration of the SLFP.
"However, they still have time to re-join the SLFP and attend the convention," he added.
Former SLFP Treasurer S.B. Dissanayake and Dilan Perera are the latest to join the SLPP relinquishing their SLFP membership.
SLFP convention will take place today under the auspices of President Maithripala Sirisena.
