HONG KONG, March 1 (Reuters) - Protest slogans rang out as about 1,000 people gathered outside a Hong Kong court on Monday for the hearing of 47 democracy activists charged with conspiracy to commit subversion, as authorities intensify a crackdown on the opposition.
Security was tight, with more than 100 police officers deployed outside the West Kowloon court, in the largest rally this year despite social-distancing rules to curb the spread of coronavirus.
The activists are accused of organising and participating in an unofficial primary poll last July aimed at selecting the strongest candidates for a legislative council election that the government later postponed, citing the coronavirus.
Authorities said the informal poll was part of a plan to "overthrow" the government, further raising alarm that Hong Kong has taken a swift authoritarian turn since Beijing imposed a national security law on its freest city last June.
"This is the most ridiculous arrest in the history of Hong Kong," said Herbert Chow, 57, who was queuing outside the court and wearing a black face mask. "But I have confidence in our judicial system to restore justice. It’s the last line of defence."
Many were dressed in black, the colour associated with the 2019 anti-government protests, while some chanted: "Liberate Hong Kong, revolution of our times" and "Fight for freedom, stand with Hong Kong," popular slogans during the unrest.
Others raised the three-finger salute that has become the symbol of protest against authoritarian rule in Myanmar.
The activists - 39 men and eight women, ages 23-64 - were charged on Sunday under the national security law, which punishes what China broadly defines as secession, subversion, terrorism and collusion with foreign forces with up to life in prison.
The queue to enter the court stretched several hundred metres, nearly reaching around the entire block.
'FULL FAITH'
Several foreign diplomats also queued.
Jonathan Williams, a British diplomat at the U.K. consulate in the city, said: "It’s clear that the use of the national security law is going much broader than the Chinese and Hong Kong authorities promised."
He added, however, that the UK government had "full faith in the independent judiciary," to deal with the defendants fairly and impartially without political pressure.
