Nathan Law on the future for pro-democracy activists in Hong Kong

In the past 25 years since Hong Kong was handed over to China from British rule, the self-government and freedoms it was originally promised have gradually been eroded. After the Umbrella Movement in 2014, Beijing's controversial extradition law in 2019 and its equally controversial national security law a year later, there's little space left for civil liberties in Hong Kong. Nathan Law, who became its youngest legislator in 2016, is now an exiled activist whose recently published book gives an account of China's growing authoritarianism and what activists can do to confront it. He joined us for Perspective from London.
