Tsarukyan’s promise to make his announcement from 1-5 December was never carried out because it was clear he will be in Brussels from 4-6 of December. “Zhoghovurd” reports Tsaukyan’s speaker stated the leader of the PAP will not make an announcement from Brussels.
Thus the statement will be late for some 2-3 days.
As “Zhoghovurd” states, Tsarukyan gave different promises to Sargsyan, Kocharyan and Ter-Petrosyan and they do not know which of them was closer to fulfillment, that is why they keep silent and wait for him to make his announcement.
