The ruling bloc began deliberations in the Lower House on an anticorruption bill Thursday as opposition lawmakers continued their boycott.

During Thursday's plenary session, the ruling triumvirate -- the Liberal Democratic Party, New Komeito and New Conservative Party -- explained the contents of their jointly proposed bill to ban lawmakers from receiving money in return for political favors.

All the opposition parties -- including the Democratic Party of Japan, Japanese Communist Party, Social Democratic Party and Liberal Party -- have been boycotting Diet sessions to protest the ruling camp's move to revise the way in which Upper House members are elected.
