On 20 November, Armenia’s Defence Minister Davit Tonoyan submitted his resignation following Armenia's losses in the Karabakh war. 

The Adviser to Armenian Prime Minister Nikol Pashinyan Vagharshak Harutyunyan, who was the Armenian Minister of Defence in the period 1999-2000, was named as Tonoyan’s successor. 

In a statement issued right after his resignation, Tonoyan said: “Am I satisfied with my performance during the war and the run-up to it? I think that some conceptual directions, which I did not have enough time to complete, need a revision. In this sense, I am ready to bear my share of responsibility.” He also indicated at the same time that he believes now is not the right time to evaluate his track record. “The existing situation needs to be defused,” he said. 

Besides Tonoyan, Armenia’s Minister of Emergency Situations Felix Tsolakyan and Minister of Labour and Social Affairs Zaruhi Batoyan also resigned. Andranik Piloyan was named as Tsalokyan’s successor, while Mesrop Arakelyan was named as Batoyan’s successor. The Armenian information portal analitik.am reported that the country’s Minister of Education, Science, Culture and Sports Arayik Harutunyan also submitted his resignation and would be replaced by his Deputy Zhanna Andreasyan.

Armenia’s Ministry of Defence (MOD) responded to the statements made by its former Chief Inspector Movses Hakobyan regarding the reasons why Armenia lost the war (Caucasus Watch reported). The MOD stated that Hakobyan made extremely dangerous statements, revealing the structure of the Armed Forces and the features of military units.  It further underscored that Hakobyan’s statements were not accurate especially those statements on the acquisition of weapons, uselessness of the SU-30SM fighter jets, non-use of air defence systems OSA, termination of the replenishment of troops on the third day of the war, disclosure of unacceptable topics of international military cooperation, and that the MOD made 100% false information regarding the dynamics of the war.

Meanwhile, the citizens of Armenia’s capital of Yerevan have shut down streets in the city, demanding the country’s Prime Minister Nikol Pashinyan’s resignation. It was reported that the police apprehended demonstrators who shut down the Baghramyan Avenue-Demirtchyan Street intersection and amongst them were Head of Henaket Analytical Center Tigran Abrahamyan, former chief of staff of the National Assembly of Armenia Ara Saghatelyan and Head of Green Future environmental movement Vahagn Varagyan. The leader of the Armenian far-right political party “Adekvad” Artur Danielyan wrote on Facebook that virtually all the members of his party were taken to the police station while blocking the intersections.

It was also reported that the country’s Constitutional Court (CC) suspended the provision of the Armenian government's legal regime of emergency situation, with which physical entities and mass media were prohibited from expressing different opinions from the official one, and recognised such provisions as unconstitutional, following the calls of the country’s Human Rights Ombudsman. The country’s National Assembly decided to convene a special session on 26 November, in which the issue on lifting martial law in the country will be discussed. The US ambassador to Armenia Lynne Tracy condemned the political violence in the country and encouraged all stakeholders to abide by the rule of law.
