Following up a series of letters exchanged between main SYRIZA opposition leader Alexis Tsipras and his Democratic Left (DIMAR) counterpart Fotis Kouvelis, representatives of the two parties are scheduled to meet for talks on Thursday.
Analysts say Thursday's meeting is one more step in SYRIZA's efforts to forge a broader political alliance ahead of Greece's Presidential election in March next year. SYRIZA's plan is to stop Parliament from electing a successor for President Karolos Papoulias and, as a result, trigger early elections.
The DIMAR leader has recently called for talks to forge a progressive alliance for Greece.
Dimitris Vitsas will on Thursday lead the SYRIZA delegation while DIMAR will be represented by Thanassis Theocharopoulos.
