More than half of the public opposes revising the government's interpretation of the Constitution just for the sake of engaging in collective self-defense, a survey says.

According to a weekend telephone survey on the issue of collective defense, or aiding an ally that comes under military attack, 53.1 percent of the respondents oppose the change sought by Prime Minister Shinzo Abe and 37.0 percent support it.

The survey, conducted Sunday and Monday by Kyodo News, also found the public approval rating for Abe's Cabinet has jumped to 54.2 percent, up 6.6 points from two weeks ago, when it plunged after the secrecy law was rammed through the Diet.
