An aide-turned-critic of former President Park Geun-hye on Tuesday won the nomination of a splinter conservative party for the presidential election in May.
Rep. Yoo Seong-min received 62.9 percent of the vote in the primary of the Bareun Party, officials said, making him the first official party nominee ahead of the May 9 vote.
Bareun, which means "righteous" in Korean, split from Park's then ruling party in the wake of her impeachment over a corruption scandal.
Yoo's victory was widely expected after he won 59.8 percent of the votes in an early part of the primary against Gyeonggi Province Gov. Nam Kyung-pil.
The nominee was announced during a convention at Olympic Park in eastern Seoul.
Yoo is a four-term lawmaker who served as chief aide to Park when she was head of the then-Grand National Party in 2005. The two fell out in recent years after Yoo openly expressed opposition to Park's policies.
The minor party will likely face an uphill battle as the election landscape is heavily tilted toward the liberal camp, according to observers.
In the latest presidential poll by Realmeter, Yoo and Nam garnered 2.2 percent and 1 percent, respectively. (Yonhap)
