Intense intra-party pressure on People Power Party leader Jang Dong-hyeok has driven trader consensus to an 87% implied probability of his ouster by June 30, amid the party's approval rating plunging to a record-low 15% ahead of June 3 local elections. Senior figures including Seoul Mayor Oh Se-hoon have publicly urged his resignation, citing internal divisions and criticism over his recent U.S. trip as distractions from domestic woes. Despite Jang rejecting calls to step down and vowing to face post-election evaluation, ongoing infighting and poor polling signal likely leadership change if results disappoint, reflecting historical patterns of South Korean opposition parties replacing chairs after electoral setbacks.
