The outgoing Justice Secretary, Teresa Cheng, says she has served Hong Kong "without fear or favour" and has felt Beijng's care for her over the past four years.

In a blog post published on Saturday, Ms Cheng looked back on her four years in office. She said she was grateful to the central government for its trust and support, which have allowed the city to conclude a number of arrangements with the mainland and improve cooperation with other jurisdictions and international organisations.

"I was also deeply moved by the unfailing care from the central government after I was attacked in London," she wrote, referring to an incident in 2019 where the minister was surrounded by Hong Kong protesters angry at the government's handling of social unrest in the SAR. She suffered a broken and dislocated left wrist in the altercation.

The Chinese Embassy arranged for Ms Cheng to be transported to Beijing for check-ups and medical treatment.

The secretary also wished her successor the very best in the job of upholding the rule of law in Hong Kong.
