Kyrgyzstan's three-party ruling coalition broke up Friday, one day after President-elect Almazbek Atambayev's inauguration.

Social Democratic Party (SDPK) leader Chynybay Tursunbekov said his party decided to pull out of the coalition because of disagreements among the trio coalition, adding his party hoped the president would give the SDPK a mandate to form a new coalition.

Launched about a year ago, the ruling coalition solved many significant problems.

However, it collapsed because of "the lack of effective mechanisms to implement a cohesive reform policy within the alliance," Tursunbekov said.

The ruling coalition consisted of 77 deputies from three parties -- the Social Democratic Party, the Republic, the Ata Zhurt (Fatherland).

It is unknown which party President Atambayev would instruct to form a new majority coalition, but local experts believed the mission probably will go to the SDPK.

On Thursday, Atambayev officially took office as president of Kyrgyzstan. At the same time, he quit the post of prime minister, which led to the resignation of the government.
