Anchor: As the minor opposition People's Party elected Ahn Cheol-soo as its new leader Sunday, the nation's five major political parties have all established formal leadership 110 days after the May ninth presidential election. The five leaders are set to cooperate with and compete against one another ahead of the provincial elections next June.
Kim Soyon has more.
 
Report: With the exception of the ruling Democratic Party whose chairwoman Choo Mi-ae led the party from before the May presidential election, the other four major parties - the Liberty Korea Party(LKP), People's Party, Bareun Party and Justice Party - have all elected new leaders after the election.
 
The People's Party was the last to elect its leadership, including leader Ahn Cheol-soo, in a party convention held at the National Assembly on Sunday. 
 
The main opposition Liberty Korea Party's Hong Joon-pyo was elected party chief on July third.
 
His election marked the normalization of the LKP's leadership for the first time in half a year.
 
The minor conservative Bareun Party also elected three-term lawmaker Lee Hye-hoon as party chairwoman in late June, ending its leadership vacuum 48 days after the presidential election.
 
The progressive Justice Party also held a convention on July eleventh and elected Lee Jeong-mi as its new leader.
 
Unlike the four opposition parties, the ruling Democratic Party, which won the nation's top office seat, continued with Choo Mi-ae's leadership.
 
Choo on Sunday held a news conference to mark her one year in office.
 
Noting that all five major parties now have a newly elected leadership, she said that an era of truly cooperative politics has dawned. 
 
She promised to seek a path together with the opposition unless their direction and stances are sharply different.
 
However, People's Party Chairman Ahn Cheol-soo stressed in his acceptance speech that his party will serve to check the government's self-righteousness and pride.
 
The conservative camps including the LKP and Bareun Party have also vowed their intention to put a stop to the Moon Jae-in administration’s unilateral advance. 
 
Battles of wit and power struggle are expected on the road ahead as the five parties carry out state affairs.
