Mongolian Prime Minister Gombojav Zandanshatar has stepped down after losing support of the country's parliament, vacating the pivotal role after taking office just four months ago.
It wasn't immediately clear who might succeed Zandanshatar, who is acting prime minister until a successor is named, or whether he would challenge his dismissal.
He was named prime minister in June.
The political upheaval comes at a critical time because the budget for next year has yet to be passed.
Teachers, who are demanding salary hikes in the budget, went on strike this week, and medical doctors are threatening to do so too.
Mongolian politics has been rocked by waves of volatility in recent years amid public anger over corruption and a weak domestic economy.
The dismissal of two prime ministers within months will also cast uncertainty over policy continuity and will also erode investor sentiment for the resources-rich country.
