Former Livedoor Co. President Takafumi Horie denied in court Tuesday that he had control over accounting at Livedoor Co., saying he had no knowledge of day-to-day transactions that allegedly violated securities laws.

Horie, 34, testifying for the first time in his highly publicized trial, painted former Livedoor Chief Financial Officer Ryoji Miyauchi, who has pleaded guilty in a separate trial, as having direct responsibility for running the company.

"The basic leader was Mr. Miyauchi in accounting," Horie said during questioning by his defense team. Miyauchi has testified that Horie, while not directly in charge, shared responsibility for the wrongdoing.
