On June 9, MPs Phakamon Nunanan (party-list), Rukchanok Srinork (Bangkok), and Phanida Mongkolsawat (Samut Prakan) from the People's Party submitted a letter to the Revenue Department requesting an investigation into the source and financial trail of 12 million baht in cash found in a condo—claimed by Taweewat Saengkaew, an advisor to an NBTC board member.

MP Phakamon stressed this wasn’t just about whose money it is, but where it came from. As an NBTC advisor serving on several powerful subcommittees, Mr. Taweewat had influence over matters involving massive national interests—such as the True-DTAC merger, funding for the World Cup broadcasting rights, and management of billion-baht telecom funds.

She said Mr. Taweewat had previously opposed NBTC authority over the True-DTAC merger, which raised concerns given the 12 million baht discovery, along with a letter from the NBTC bearing his name.

MP Rukchanok added that many viewed Mr. Taweewat's explanation—claiming he simply "forgot" the cash or blamed a plumbing leak—as laughable, but she argued the matter must be taken seriously. She noted that his wife hadn’t declared the money in any asset disclosure and Taweewat’s reported annual income was just one million baht—raising questions about the money’s origin.

MPs called for urgent involvement from the Revenue Department and NACC. They also criticized the NBTC's apparent inaction and hinted at deeper systemic rot, drawing comparisons to past corruption scandals.

MP Phanida pointed to a June 29 frequency auction, questioning if the cash could be linked to it. With only two major telecom players expected to participate, she challenged whether the low reserve price was just and truly competitive.

They also highlighted concerns over the lack of oversight in two key telecom funds—USO and BCP—worth billions annually. Evidence allegedly points to collusion in funding allocations, with further disclosures expected once documentation is complete.

The MPs warned that NBTC leadership—especially its chair, who also heads these funds—lacks transparency and accountability. They vowed to continue investigating and publicly exposing corruption tied to these institutions.
