Pro-democracy campaigner Jimmy Lai has been found guilty of national security offences in Hong Kong.
The media tycoon and British citizen, 78, was arrested in August 2020 after China imposed a national security law following massive anti-government protests in Hong Kong.
Sky News' Asia correspondent Helen-Ann Smith, who is at West Kowloon Law Courts Building, said Mr Lai looked "drawn and thin" as he listened to the verdict being delivered.
He had previously been sentenced for several lesser offences during his five years in prison.
Mr Lai, who founded the now-defunct pro-democracy newspaper Apple Daily, was charged with two counts of conspiracy to commit collusion with foreign forces to endanger national security, as well as one count of conspiracy to distribute seditious publications.
He has been found guilty of all three charges.
His trial, heard by three judges approved by the government without a jury present, has been closely monitored by the UK, the US, the European Union and political observers as a barometer of media freedom and judicial independence in the former British colony, which returned to Chinese rule in 1997.
Mr Lai has spent more than 1,800 days in solitary confinement. His family say his health has worsened as a result and that he suffers from diabetes, high blood pressure and heart palpitations.
In August, Mr Lai's son, Sebastien, told Sky News that unless the British government (of which Mr Lai is a citizen) intervenes, his father "is most likely going to die in jail".
Sebastien said his father's death would not just be a personal tragedy, but a huge problem for both the Hong Kong authorities and Beijing's government.
"You can't tell the world you have the rule of law, the free press and all these values that are instrumental to a financial centre and still have my father in jail," he told Sky News.
"And if he dies, that's it, that's a comma on Hong Kong as a financial centre."
