A panel of experts endorsed by Prime Minister Shinzo Abe will postpone until May its submission of a report proposing that Japan lift its ban on exercising the right to collective self-defense, a government source said Wednesday.

The decision to postpone the report for about a month will give the administration more time to gain support from New Komeito, the junior coalition partner of the ruling Liberal Democratic Party, the source said.

New Komeito has been notified of the delay, the source said.
