Rights groups dismiss ‘sham conviction’ of media tycoon on national security offences in city’s most closely watched rulings in decades

• The rise and fall of Jimmy Lai, whose trajectory mirrored that of Hong Kong itself

Jimmy Lai, the Hong Kong pro-democracy media tycoon, is facing life in prison after being found guilty of national security and sedition offences, in one of the most closely watched rulings since the city’s return to Chinese rule in 1997.

Soon after the ruling was delivered, rights and press groups decried the verdict as a “sham conviction” and an attack on press freedom.

Progressing from child labourer to billionaire, Lai used his power and wealth to promote democracy, which ultimately pitted him against authorities in Beijing

On Monday, a Hong Kong court convicted Jimmy Lai of national security offences, the end to a landmark trial for the city and its hobbled protest movement.

The verdict was expected. Long a thorn in the side of Beijing, Lai, a 78-year-old media tycoon and activist, was a primary target of the most recent and definitive crackdown on Hong Kong’s pro-democracy movement. Authorities cast him as a traitor and a criminal.
