Midland Holdings' former deputy chairman has denied market speculation that he orchestrated a protest in February by hundreds of property agents who demanded full payment of their commissions.
Albert Wong Kam-hong says he was then taking care of his dying son at a hospital.
'The accusation is unfounded and defamatory,' Wong said.
'The protest was simply a labour dispute, and the issue has been submitted to the Labour Department.'
Wong yesterday broke his silence on the matter and resigned with immediate effect, three weeks before he was due to step down.
In February, more than 200 Midland agents gathered outside World-Wide House in Central, while dozens of its directors and some managers stormed the offices on the 25th floor.
They were demanding to meet chairman Freddie Wong Kin-yip, and pressed for 'the same rate of commission that other property agencies provide'.
