WAKAYAMA — Prefectural governors warned Friday that the ruling bloc's loss in Sunday's Upper House election means more political gridlock ahead, and unless local leaders work with the coalition and the opposition camp to pass legislation and secure more tax income, regional growth and quality of life will quickly deteriorate.

"The Upper House election have given birth to a 'twisted Diet.' If this stops policy from getting implemented, people's lives and the future of Japan will be deeply affected," the National Association of Governors said in a statement issued at the end of a two-day annual meeting in Wakayama.

The association specifically warned that the time for factional and party infighting is over.
