Kyrgyzstan's Social Democratic party, led by close allies of President Almazbek Atambayev, has quit the parliamentary coalition because of disagreements with its partners, parliament deputy Azamat Arapbayev said on Monday.

Arapbayev, a member of the Social Democratic party, said the move, which will trigger the creation of a new coalition and may lead to the resignation of the cabinet, was a result of other coalition members' refusal to support constitutional reforms proposed by Atambayev.
