A massive crowd in Yerevan's central Republic Square sang the Armenian national anthem at a celebration rally following Nikol Pashinyan's election
Yerevan (AFP) - Tens of thousands of Armenians poured on to the streets of the capital Yerevan Tuesday to celebrate opposition leader Nikol Pashinyan's election as prime minister.
Armenia's parliament elected Pashinyan after he spearheaded weeks of mass protests against the ruling party, transforming the country's political landscape.
A massive crowd in Yerevan's central Republic Square sang the Armenian national anthem at a celebration rally following his election.
"From now on, nobody will violate the Armenian people's rights and freedom!" Pashinyan told the crowd, to shouts of "Nikol! Nikol!"
Groups of youths danced to folk music and drumrolls and many held Pashinyan portraits.
"I am so happy that what happened in Armenia in recent weeks was peaceful. It's a great historic day," Gohar Harutyunyan, a 39-year-old financier, told AFP.
"We understand that things can't change overnight. But the most important thing has already been done," said Ruzanna Sargsyan, a 42-year-old economist.
- Ruling party backs protest leader -
Lawmakers voted 59 to 42 to approve Pashinyan for the job, after the ruling Republican Party came round to backing his premiership bid on his second attempt.
The party had narrowly voted him down last week, plunging the Caucasus nation into its most serious political crisis in years.
The hugely popular Pashinyan had in recent weeks piled pressure on the Republican Party through an unprecedented campaign of civil disobedience, leading to the shock resignation of veteran leader Serzh Sarkisian, a week after he shifted to the newly-empowered role of prime minister after serving for 10 years as president.
"My first work after my election will be ensuring a normal life in the country," Pashinyan said ahead of the vote.
"There will be no corruption in Armenia. Armenia will once and for all turn the page of political persecutions."
The 42 year-old added that Armenia's relations with ally Russia will "remain a priority".
"Military cooperation with Russia is an important factor in ensuring our country's security," he said, referring to a two-decade long conflict his country is locked in with neighbouring Azerbaijan.
"We will (also) be developing relations with European countries and the United States, with Iran and Georgia, China and India," he added.
Russian president Vladimir Putin congratulated Pashinyan in a statement released by the Kremlin on Tuesday.
- 'Ensuring stability' -
The head of the ruling Republican Party's parliamentary faction, Vagram Bagdasaryan, said his party backed Pashinyan to "ensure stability" in the country.
"We did not change our position. We are against Nikol Pashinyan's candidacy, but the most important thing for us is to ensure stability in the country," Bagdasaryan said ahead of the vote.
Pashinyan called for an end to the protests after the Republicans -- who have 58 MPs in the 105-seat legislature -- promised to back him in the second attempt.
The former newspaper editor also secured the support of two other major political parties -- Prosperous Armenia and the Armenian Revolutionary Federation (Dashnaktsutyun) -- which nominated him for the post together with his opposition Elk coalition.
Pashinyan was the only candidate for the premiership.
Political analysts say Pashinyan's election is unlikely to put an end to the political crisis, as the ruling party retains a majority in parliament and could well block his initiatives.
Analyst Vigen Akopyan said snap elections looked certain.
Another analyst, Stepan Safaryan, said Armenia was now entering "an interesting period of disequilibrium".
Pending fresh elections "Pashinyan must manoeuvre between the will of the people and the parliamentary ruling party that he does not belong to and which cannot begin supporting him", he said.
Pashinyan's protest movement had accused Sarkisian of a blatant power grab.
In December 2015, controversial constitutional amendments initiated by Sarkisian were passed after a referendum that saw some 63 percent of the voters backing the country's transformation into a parliamentary republic with executive powers fully concentrated in the hands of a prime minister.
Council of Europe observers said the referendum was marred by allegations of large-scale vote-buying, multiple voting and other irregularities.
Critics accuse Sarkisian and his Republicans of corruption, being under the influence of powerful oligarchs, and of failing to tackle widespread poverty.
