Justice Minister Pol Lt Gen Rutthapon Naowarat denied claims that the government had used a Department of Special Investigation (DSI) probe to pressure People's Party MP Pawoot Pongvitayapanu into softening his stance on the TH-AI Passport project.
Speaking at Government House on Tuesday, Pol Lt Gen Rutthapon said the DSI had issued summonses to more than 20 people last week, including Mr Pawoot, a People's Party list MP, in connection with an investigation into an alleged illegal forex investment scheme. Those summoned are expected to meet investigators next week to give statements.
The controversy arose after Mr Pawoot, who had previously been one of the project's most vocal critics, expressed support for its revised implementation.
In a recent social media post, Mr Pawoot argued that, since the project had already been approved, the focus should shift to ensuring taxpayers received maximum value for money. He said the opposition should continue monitoring potential risks while acknowledging improvements made to the project.
His remarks drew criticism from some supporters and fellow party members, including People's Party list MP Rukchanok Srinork, who questioned his apparent change in tone and said politicians should remain consistent in scrutinising government projects.
The minister was responding to speculation that Mr Pawoot's softened stance on the project was linked to the ongoing DSI investigation.
"There has been no discussion and no action whatsoever," Pol Lt Gen Rutthapon said when asked whether the government had exerted pressure on the opposition MP.
Asked when the DSI might file charges, he said the timing would depend on the evidence gathered by investigators, as well as testimony from witnesses and those summoned for questioning.
People's Party leader Natthaphong Ruengpanyawut later rejected suggestions that Mr Pawoot's stance was linked to the forex case. He said the party's concerns over the TH-AI Passport project remained focused on alleged procurement irregularities, including claims that specifications had been downgraded and that conflicts of interest may exist.
Mr Natthaphong also confirmed that the party was drafting a petition seeking a National Anti-Corruption Commission investigation into the project. He said details would be announced once the petition had been finalised.
He described differences of opinion within the party as normal and stressed that the debate should remain focused on procurement and transparency rather than individual politicians.
