Armenia's prime minister steps down

YEREVAN, Armenia (AP) — Armenia's prime minister says he has submitted his resignation, a move that comes in the wake of a court ruling against a pension reform he has championed.

Tigran Sargsyan announced his move on Facebook on Thursday, but didn't give his motives.

Edward Sharmazanov, a deputy speaker of parliament and member of the ruling Republican Party, said Armenian President Serge Sarkisian accepted the prime minister's resignation. The new prime minister will be nominated by the ruling party. He's to be named within 10 days, according to the Armenian law.

The resignation of Sargsyan, who served as prime minister since 2008, is widely believed to be linked to a pension reform that has drawn public criticism. Armenia's Constitutional Court ruled Wednesday that the pension legislation violated the law.
