The 2007 presidential election is expected to become a multi-person race as the pro-government and main opposition parties face internal discords that could lead to party breakup or desertion by major presidential hopefuls.
The two leading presidential contenders from the main opposition Grand National Party (GNP) are on a collision course over the rules to pick the party's standard-bearer in the Dec. 19 presidential election.
The pro-government Uri Party, which has already been torn up after mass defections by legislators, is facing a second-phase split due to feud between former party leaders and President Roh Moo-hyun.
