Hong Kong pro-democracy tycoon Jimmy Lai will take the witness stand for the first time in November in a high-profile national security trial where he is accused of sedition and colluding with foreign forces, a court said Thursday.

The charges against Lai -- founder of the now-shuttered popular Chinese-language tabloid Apple Daily -- revolve around the newspaper's publications, which supported the pro-democracy protests in Hong Kong in 2019 and criticised Beijing's leadership.

Besides sedition, the 76-year-old is also accused of two counts of colluding with foreign forces -- which carries a maximum sentence of life imprisonment -- by calling for international sanctions against Chinese and Hong Kong officials.

Lai, who pleaded not guilty to the charges in a trial that started in January, "elects to give evidence in this case", said his lawyer Robert Pang.

His testimony will start on November 20 and could run for weeks, said Esther Toh, one of the three senior judges handpicked by the Hong Kong government to try security cases.

Lai has been in custody for more than 1,300 days.

Following massive pro-democracy protests in 2019, Beijing imposed a sweeping security law to quell dissent.

The prosecution has so far called eight witnesses and played over 40 hours of Lai's talk shows and video interviews since January to mount a case against him and eight others.

Dozens of Hong Kong and foreign politicians and scholars -- including former U.S. Secretary of State Mike Pompeo -- were named as his foreign contacts and "agents".

But Lai's lawyer argued Wednesday that the prosecution failed to prove he had continued to call for sanctions after Beijing criminalised such advocacy with the security law.

Judges on Thursday ruled against Lai's defence team, calling on him to answer to all charges.

The other defendants in the case are six former executives of the newspaper and two activists, as well as three Apple Daily companies that have been taken over by the Hong Kong government.
