I. Documented controversies

01

2017

De facto merger strategy with Party of Hope in 2017, electoral debacle and resignation

No legal proceedings

Shortly after becoming Democratic Party leader, Maehara encouraged the party's candidates to seek endorsement from Yuriko Koike's new Party of Hope, effectively suspending the fielding of candidates under the DP label. The exclusion of candidates considered too liberal and the Party of Hope's poor results fractured the opposition and sparked strong criticism of his strategy. Maehara resigned.
