The acting head of Samsung Group is facing trial in South Korea for his alleged role in a corruption scandal that led to the ousting of the president, BBC reported.
Lee Jae-yong denies charges of embezzlement and perjury.
Prosecutors highlighted that the accused gave 43bn Korean won ($38m; £30m) to President Park Guen-hye’s friend for political favours.
In this aspect, four Samsung executives have also appeared in court in connection with the scandal.
However, they also deny the accusations.
Mr Lee’s case is “one of the most deep-rooted and typical cases involving unhealthy relations between politicians and businessmen,” said Special Prosecutor Park Young-Soo in his opening statement in Seoul’s Central District Court.
The Samsung vice-chairman and de facto leader Lee Jae-Yong was arrested in February on charges of bribery.
He could face at least five years in prison if convicted.
