Prominent political and legal figures around the world have condemned the “outrageously unjust” imprisonment of three of Hong Kong’s best-known pro-democracy activists, calling on China to immediately free the “political prisoners”. Joshua Wong, Nathan Law and Alex Chow – three leaders of 2014’s umbrella movement demonstrations – were jailed for between six and eight months on Thursday for their involvement in an “unlawful assembly” at the start of that historic 79-day civil disobedience campaign.
