Movement of New Forces Party leader and ex-President of Georgia Mikheil Saakashvili has published an open letter to Ukrainian President Petro Poroshenko on his Facebook page. The letter calls on Poroshenko to resign and comments on Saakashvili's previous letter to Poroshenko, which was made public on December 19, 2017.

"Admit to yourself and to your people that you and your associates are not able to change Ukraine for the better. Your voluntary resignation is practically the last chance for Ukraine to overcome the political crisis, which will only get worse," the letter says.
