Stelios Kouloglou left the Eurogroup as the main opposition in Greece continued to deteriorate.

"At the same time that a violent overthrow of SYRIZA's politics is being attempted, the situation that has developed within the party lacks seriousness, adding more fuel to the fire. In these circumstances, the situation is intolerable for those who wanted to maintain an independent stance, he writes in his letter to Stefanos Kasselakis, among other things.

Mr. Kouloglou harshly criticizes the deletion of Stefanos Tzoumakas in his letter, as well as the lack of a serious opposition and the views Stefanos Kasselakis expressed at the Union of Greek Enterprises.

"Even before you were elected, the public conversation centered on your personal affairs rather than your political platforms. SYRIZA discovered that it was supplying morning shows with gossip while Mr. Mitsotakis was left alone and unmolested to discuss politics on the news.

In the international as well as Greek history of recognized opposition parties, this has never occurred. You are primarily responsible for this, and nothing has changed despite the pertinent points. It was only yesterday that you cited, among other things, "a relationship with a girl that I was not happy with," in an attempt to defend your earlier anti-SYRIZA, conservative writings, adds Mr. Kouloglu.
