The prime minister's top panel on security issues has drafted a report to propose that Japan exercise its right to collective self-defense, requiring the government to change its interpretation of the pacifist Constitution, a source said Friday.

The advisory panel is expected to work out the details and submit a final report to Prime Minister Shinzo Abe next year. The draft was revealed on Wednesday, the government source said.

Abe wants to bolster the nation's defensive capabilities and get Japan more proactively involved in global peace and security, but the shift will require legislative revisions and a revamp of the war-renouncing Constitution.
