Prime Minister Shinzo Abe plans to create a new Cabinet minister post in charge of reworking Japan's legal framework to remove the self-imposed ban on using collective self-defense, government sources said Wednesday.

The specially assigned minister may be named in late August, and will be tasked mainly with explaining the government's stance on the controversial issue to the Diet.

Abe aims to secure Cabinet approval for lifting the ban and revising a number of laws during an extraordinary Diet session in the fall, in line with a major security policy change he is pushing, the sources said.
