Thousands of demonstrators led by Armenian opposition leader Nikol Pashinyan held a mass rally at the Republic Square, in Yerevan on Monday. Earlier Pashinyan, as the head of the opposition 'Way Out' (Yelk) Faction, has been nominated for the post of Prime Minister, becoming the sole candidate. With reference to the Armenian Constitution, «In case the Prime Minister submits a resignation or... Еще in other cases of the office of the Prime Minister becoming vacant, the factions of the National Assembly shall be entitled to nominate candidates for Prime Minister within a period of seven days after accepting the resignation of the Government. The National Assembly shall elect the Prime Minister by majority of votes of the total number of Deputies.» Armenians have been on the streets since April 13, after the ruling RPA nominated former President Serzh Sargsyan for the prime minister's post. On April 23, Sargsyan stepped down after a few days in his new post amid massive actions against his premiership.
