Effie Achtsioglou on Wednesday announced her decision to run as a candidate for the leadership of main opposition SYRIZA-Progressive Alliance, ahead of the party's Central Committee meeting at the weekend.

Achtsioglou made her announcement in the Colonnade of the Athens Conservatoire on Rigillis Street.

"We are faced with a time of critical decisions," Achtsioglou said, and added: "We must work effectively, with persistence, to once again create the prospect of a strong SYRIZA-Progressive-Alliance."

She underlined that "in order to realise our vision of a society of high expectations, we need a new SYRIZA-Progressive Alliance, an effective, modern, methodical SYRIZA, able to respond to new challenges, which will highlight the collective effort and utilise our collective intelligence."

Achtsioglou noted that her candidacy for the position of SYRIZA-Progressive Alliance leader and leader of the main opposition, "inevitably concerns not just SYRIZA, it concerns Greece, it concerns society."
