A bill for a new system blocking convicted sex offenders from jobs involving children will not be submitted in an extraordinary parliamentary session expected next month, a government source said Saturday.

The decision to drop the plan comes after a slew of criticism from within the ruling Liberal Democratic Party of the bill's contents, including that more professions should be subject to the system.

The government now aims to present the bill at an ordinary Diet session next year, with the intervening period to be used to review expanding the scope of jobs affected. Ayuko Kato, minister in charge of child policies, is expected to announce the delay soon, the source said.
