Kyrgyz lawmakers have approved plans to hold a national referendum on December 11 on controversial constitutional changes.
The law setting the referendum date passed the third and final reading by a majority of votes on November 2.
If passed, the constitutional changes would strengthen the powers of the prime minister, a move President Almazbek Atambaev's opponents say is aimed at extending his grip on power.
The constitution bars Atambaev from running for a second presidential term when his mandate ends next year, and critics say the proposed reform would enable him to become a powerful prime minister.
Last week, the government resigned after Atambaev's Social Democratic Party quit the ruling coalition because some partners refused to support the proposed constitutional changes.
