Hong Kong’s leader, Carrie Lam, is the person responsible for mobilising the biggest protests in the city’s history, the freed student activist Joshua Wong has said. The 22-year-old, who was the face of the last major demonstrations in Hong Kong in 2014, was released from jail on Monday following a two-month term for contempt of court. He said that despite Lam’s “sincere and solemn” apology at a press conference, and her hint that the extradition law that sparked this month’s mass protests had been effectively retracted, the chief executive had not met any of her critics’ demands.
