Japan's internal affairs minister resigned on Sunday in connection with a funding scandal, becoming the third cabinet member to leave in less than a month in a severe blow to Prime Minister Fumio Kishida's already shaky support.
Kishida's approval ratings have sunk after the July assassination of former Prime Minister Shinzo Abe revealed deep and longstanding ties between ruling Liberal Democratic Party politicians and the Unification Church, a group that critics say is a cult.
Internal affairs minister Minoru Terada tendered his resignation to Kishida after media reports the premier was preparing to sack him. Kishida on Monday appointed Takeaki Matsumoto, a former foreign minister, to succeed Terada.
"The foundation of political commitment is the trust of the public," Kishida told reporters after appointing Matsumoto. "As a politician, I must secure the public trust by bracing up and inspecting my surroundings".
A poll conducted over the weekend, before Terada's resignation, found that only 30.5% of respondents approved of Kishida, down 2.6 points from a survey in October, Asahi TV said on Monday.
Just over half, 51%, disapproved of how he had handled the resignation of two previous ministers, Economic Revitalisation Minister Daishiro Yamagiwa and Justice Minister Yasuhiro Hanashi.
Terada, under fire for several funding scandals, has acknowledged that one of his support groups had submitted funding documentation ostensibly signed by a dead person.
Kishida said he had accepted Terada's resignation in order to prioritise parliamentary debate, including discussions on a second extra budget for the fiscal year ending in March.
Asked about the fact that three ministers have resigned since Oct 24, Kishida said he would like to apologise.
"I feel a heavy responsibility," he told reporters on Sunday.
Terada's departure could further weaken the embattled premier, whose support ratings have remained below 30% in several recent opinion polls, a level that may make it difficult for him to carry out his political agenda.
After leading the LDP to an election victory days after Abe was gunned down on the campaign trail, Kishida had been widely expected to enjoy a "golden three years" with no national elections required until 2025.
Abe's suspected killer said his mother was bankrupted by the Unification Church and blamed Abe for promoting it. The LDP has acknowledged many lawmakers have ties to the church but that there is no organisational link to the party.
A vast majority of voters also disapproved of Kishida's decision to hold a state funeral for Abe, which took place at the end of September.
Yamagiwa resigned on Oct. 24 due to his ties to the religious group, and Kishida came under fire for what voters saw as his delayed and clumsy handling of the situation.
Further damage came from the resignation of justice minister YasuhiroHanashi in mid-November for comments seen as making light of his work responsibilities, specifically signing off on executions.
Hanashi and Terada's resignations are likely to be especially painful because they were members of Kishida's faction in the LDP.
