[8] This confirmed Papandreou's split from the Panhellenic Socialist Movement (PASOK),[9] which he had led until being replaced as leader by Evangelos Venizelos in March 2012.

[1] Other well known PASOK politicians who joined KIDISO include former parliamentary speaker Filippos Petsalnikos and former minister Dimitris Reppas.

[citation needed] On 27 August 2015, PASOK officially ruled out a proposed electoral pact with KIDISO for the upcoming September 2015 snap election.

Two party members, leader George Papandreou and former PASOK minister Haris Kastanidis, were among the 22 KINAL MPs elected in 2019.

As a result of the decision by Nikos Androulakis to exercise his prerogative as party leader to retain the single Thessaloniki A seat won by PASOK–KINAL in the May 2023 and June 2023 elections, Haris Kastanidis is no longer a member of parliament.
