Aug. 15 (UPI) -- The trial of Jimmy Lai, Hong Kong media mogul, was postponed for a few days due to issues with the 77-year-old's heart.

The three judges overseeing the trial said the proceedings will resume Monday with closing arguments. Lai was given medication and a Holter monitor, which tracks the heart's electrical activity. The trial had also been delayed Thursday because of torrential rain in the city.

Lai, a citizen of the United Kingdom, founded Apple Daily, a Chinese-language newspaper published in Hong Kong from 1995 to 2021. The tabloid has been described as anti-government, pro-democracy and anti-China. He is accused of collusion with foreign forces and sedition. He has been in solitary confinement since December 2020. He faces life in prison.

Prosecutors have accused the media tycoon of requesting foreign countries to engage in "hostile activities," such as imposing sanctions, against authorities in Hong Kong and mainland China.

He allegedly conspired with senior editorial staff of Apple Daily and was the "mastermind and financial supporter" of the Fight for Freedom; Stand with Hong Kong advocacy group, which lobbied for international sanctions against Hong Kong and China.
