The trial of Jimmy Lai, Hong Kong media mogul, are postponed for a few days due to issues with the 77-year-old's heart. Closing arguments are set for Monday.

A court in Hong Kong adjourned a national security trial hearing of media mogul Jimmy Lai on Friday, due to concerns about his health, after his defense said he had been experiencing heart palpitations.

Hailed by some as a hero and scorned by others as a traitor, Hong Kong's pro-democracy media tycoon Jimmy Lai is in the final stage of his national security trial. Closing arguments were scheduled to start on Thursday for Lai, who is accused of colluding with foreign forces under a Beijing-imposed national security law.
