Bangkok: Ms. Kusumalawatee Sirikomut, Chairperson of the Advisory Board of the Thai Progressive Party and former Senate candidate, has taken a decisive step by submitting a letter to Pol. Col. Yutthana Praedam, Director-General of the Department of Special Investigation (DSI), urging a strict investigation into the alleged collusion in the Senate election of 67 members. The letter was received by Pol. Col. Woranan Srilam, Director of the Consumer Protection Division and spokesperson for the DSI.

According to Thai News Agency, Ms. Kusumalawatee emphasized the need for the DSI to perform its duties without succumbing to external pressures, particularly concerning the Khao Kradong land issue in Buriram Province. She highlighted the necessity to revoke the Supreme Court's ruling, which had previously determined that the statute of limitations could not be applied to the rights concerning the State Railway of Thailand's (SRT) land. The 1921 land title explicitly prohibits private ownership of SRT land without a royal decree, indicating that the land is state property. Ms. Kusumalawatee argued that any titles issued by individuals in power must be revoked and called for charges against Prime Minister Anutin Charnvirakul and the Minister of Interior under Section 157 for neglect and misconduct. She stressed the importance of reclaiming the land to prevent future legal violations and requested this case be treated with special attention. Furthermore, she has petitioned the National Anti-Corruption Commission (NACC) to remove Anutin Charnvirakul from his position over his alleged involvement with land in Khao Kradong and approving a substantial budget for the 2026 MotoGP event despite unresolved ownership issues.

Ms. Kusumalawatee also addressed concerns regarding Mr. Nattawut Saikua, a campaign assistant for the Pheu Thai Party. He had claimed that the Special Prosecutor's Office returned the case file on senator-related sedition and money laundering to the DSI due to insufficient evidence against the eight suspects. She indicated that all 1,200 witnesses need to be thoroughly questioned to solidify the case, with a particular focus on financial trails and money laundering activities. She regretted that the Election Commission's three-quarters majority dismissed the financial evidence from the DSI, questioning if this was a coordinated action.

Ms. Kusumalawatee expressed continued faith in the DSI's investigation, believing the Senate collusion and money laundering case might involve more than the eight individuals initially suspected. While the central investigation and inquiry subcommittee, committee number 26, concluded the Senate collusion case under election law involving 229 cases, it remains pending with committee number 36 for issue resolution, within an extendable 90-day period. This delay has prevented the case from reaching the Election Commission board, leading her to suspect possible interference or assistance to certain individuals within the Election Commission.
