The ruling Liberal Democratic Party promised Friday in its campaign platform for the July 10 Upper House election to push Abenomics to its "upper limit" to revive the nation's stagnant economy.

Opposition parties seeking to wrest power from the LDP and its coalition partner Komeito argue the announcement earlier this week that a consumption tax hike will be postponed for the second time signals the failure of Prime Minister Shinzo Abe's namesake monetary and fiscal policy mix.

LDP policy chief Tomomi Inada announced the campaign pledge at a news conference Friday afternoon after it was broadly accepted by the party's executive council earlier in the day.
