Regarding the issue of illicit monetary exchanges surrounding the position of Speaker of the Fukuoka Prefectural Assembly, voiceprint analysis commissioned by FNN has revealed that the audio data released by whistleblower Assembly Member Genaki Yoshimatsu is, with a 99.99% probability, the voice of Assembly Member Masayuki Nakao. Assembly Member Yoshimatsu has testified that he paid over 20 million yen to executives of the LDP prefectural assembly group regarding the speakership, and he recorded audio in which Nakao allegedly instructed the handover of cash. However, Assembly Member Nakao has consistently denied these allegations.
