Illegal bookmakers are partly to blame for the loss of more than $800 million in revenue by the Jockey Club, it was claimed yesterday. Club chief executive Lawrence Wong said illegal bookmakers had become increasingly high profile. 'If we do not strike at these activities now, everything the Government and the Jockey Club has achieved in the past decades in combating illegal bookmaking will be lost,' he said. 'It will be Hong Kong people who suffer in the end.' Police recently arrested 16 illegal bookies with an estimated combined turnover of $80 million per race meeting. 'This is equivalent to $5.7 billion per year, which is more than the annual Mark Six lottery turnover,' Mr Wong said. The amount, if placed in bets through the Jockey Club, would have meant $750 million betting duty paid to the Government, and about $60 million given to charities, he said. The club's turnover this year was $91.5 billion.
