Tigran Khachatryan’s move comes as the government is under pressure to quit, after agreeing to end the Nagorno-Karabakh conflict.

Armenian economy minister Tigran Khachatryan has tendered his resignation, his spokeswoman said on Tuesday, following criticism of the government over a peace agreement that secured advances for Azerbaijan in Nagorno-Karabakh after six weeks of fighting.

The announcement, made on Facebook by Khachatryan’s spokeswoman Anna Ohanyan, follows the appointment of a new defence minister and minister of foreign affairs last week.

Under the Russia-brokered deal, Nagorno-Karabakh’s ethnic Armenian leaders are handing over swaths of territory they had controlled for decades but had been internationally recognised as part of Azerbaijan.

Pashinyan, who has rejected calls to resign, last week unveiled a six-month action plan that he said was designed to ensure Armenia’s stability.
