Ko Wen-je, the leader of Taiwan's third-largest political party, the Taiwan People's Party (TPP), has been arrested amid a corruption investigation linked to a property development project from his time as mayor of Taipei. His arrest follows nearly 19 hours of questioning and a raid on his home and party headquarters, raising concerns of possible collusion. Ko, who has denied any wrongdoing, has agreed to temporarily step down as party chairman while the investigation proceeds, and he expressed remorse to his supporters. Notably, the TPP also acknowledged misreporting campaign funds during Ko's presidential run earlier this year. The scandal highlights growing scrutiny of political figures in Taiwan, especially concerning real estate dealings and campaign finance issues.
