Wallop Tangkananurak said some ten NLA members had separately telephone discussions with some cabinet members including Deputy Prime Minister Pridiyathorn Devakula who proposed the amendment.
Wallop, a child rights advocate, said that the group informed the government that the amendment has no measures to prevent young people from the two and three-digit lotteries.
He believed that the government decided to withdraw the bill because they shared the same concerns with the NLA.
Earlier Pridiyathorn said the government withdraw the bill for further reviewing. The withdrawal of the bill at the second day of the National Legislative Assembly indefinitely postponed issuing of two and three-digit lotteries.
Pridiyathorn told reporters briefly that he decided to withdraw the bill as it has not yet had measures to protect the young from buying the lotteries.
The deputy prime minister earlier in the day said that two and three-digit lotteries would be delayed indefinitely pending scrutinising in the National Legislative Assembly.
At first the government delayed the issuing of the lotteries to December 30, but the NLA has not yet decided on whether the lotteries should be legalised or not. "The pending discussion on the matters in the NLA automatically delayed the lotteries indefinitely or until the NLA can decide on the them," Pridiyathorn said earlier.
