Earlier on Wednesday, Serzh Sarkisyan was sworn in as Armenian president as the former Soviet republic looked to put recent electoral violence behind it.
At a meeting on Tuesday, the Council of Armenia's ruling Republican Party voted unanimously in favor of Tigran Sarkisyan as premier. He is not related to the new president.
In line with Armenia's constitution, the new government should be formed within 20 days once a premier has been appointed. The government then should within 20 days present its program to the National Assembly - Armenia's parliament.
Tigran Sarkisyan is an economist by education. He was appointed head of Armenia's Central Bank in 1998, and reappointed to the post for 7 years in 2005.
