The bills, the result of several weeks of wrangling between ruling and opposition groups, are expected to clear the full lower house later in the evening.

Still unresolved are measures to handle weak banks before they fail. The ruling Liberal Democratic Party (LDP) and opposition groups remained apart on such issues as allowing the injection of public funds into such troubled banks.

The government, however, wants these measures to be enacted by the end of the current session of parliament on October 7. Several lawmakers have said for that to happen the session needs to be extended by a week or 10 days.

Miyazawa is to leave for Washington at 8 pm (1100 GMT) after the lower house passage of the bills to meet his counterparts from Group of Seven (G7) -- Britain, France, theUnited States, Germany, Italy, Canada and Japan -- tomorrow.

The bills include several options to deal with failed bank and the establishment of a new independent committee which will share financial planning power with the finance ministry.

After the expected passage, the bills will need to be approved by the upper house before they become law.
