The New Reform Party (NRP), a broad coalition formed to challenge South Korea’s two dominant political parties in the upcoming April parliamentary elections, collapsed on Tuesday, 11 days after its creation. Disagreements over election strategy and policy direction between co-leaders Lee Nak-yon, a former prime minister and former leader of the main opposition Democratic Party (DP), and Lee Jun-seok, a former leader of the ruling People Power Party (PPP), led to the dissolution.

Lee Nak-yon has since announced his intent to revert to leading his newly established New Future Party. This development throws a wrench into the plans of South Korea’s minor third parties to present a united front against the entrenched ruling and main opposition parties. Before its dissolution, the NRP was the third most popular in the country less than a week after its establishment.
