The founder of grocery chain AbouThai, who pleaded guilty to subversion in Hong Kong’s largest national security trial, has severed ties with the “yellow economic circle”, a loose business coalition that had backed the city’s 2019 anti-government protests.

Mike Lam King-nam on Wednesday said the business was no longer linked to the “yellow economic circle”, describing the movement as “wrong” without elaborating in a Facebook post titled: “Hong Kong cannot fall into chaos, nor can it afford chaos.”

Lam is among 47 opposition bloc members who were charged with subversion for their alleged role in an unofficial Legislative Council primary poll in 2020. He earlier said he would contest the charge, but later pleaded guilty in January and agreed to testify for the prosecution.
