The main opposition Syriza party is facing continued internal turmoil as party rivals demand another internal election to challenge the leadership of Stefanos Kasselakis.
The calls for a new vote come amid concerns over Mr. Kasselakis' leadership style and the party's direction.
Mr. Kasselakis, a newcomer to Greek politics, won a surprise victory in the party's leadership election last September, succeeding Alexis Tsipras. However, his leadership has been met with criticism from some within the party, leading to the departure of several prominent members who formed a new party, New Left.
During a recent political secretariat meeting, several party members, including former minister Olga Gerovassili, called for another internal election to confirm Kasselakis' mandate or choose a new leader. The ultimatum to Mr. Kasselakis is to either validate his leadership through a vote or step aside.
Mr. Kasselakis responded to the criticism by warning that another election would destabilize the party and harm its supporters. He also called on his critics to pledge their loyalty to the party regardless of the outcome of any future election.
The internal strife within Syriza highlights the challenges the party faces as it seeks to rebuild and regain its footing in Greek politics.
The calls for a new leadership election could lead to further divisions within the party, potentially weakening its ability to challenge the ruling government.
