Yuichiro Tamaki, leader of Japan's Democratic Party for the People (DPP), has admitted to an extramarital affair following a report by tabloid SmartFlash, stating that the claims are 'basically true.' This revelation comes just hours before a crucial vote to determine the next prime minister, which positions Tamaki as a significant player in the political landscape. He expressed regret for any trouble caused by the affair during a press conference. The DPP holds considerable influence in the vote as the ruling Liberal Democratic Party (LDP) seeks to maintain power after losing its parliamentary majority. Despite the DPP's potential to support some LDP policies, Tamaki has stated that party members will not vote for Prime Minister Shigeru Ishiba, complicating the latter’s legislative agenda. This situation highlights Tamaki's dual role as a key political figure and a subject of personal controversy during a pivotal moment in Japan's politics.
