Tokyo | Japanese voters are set to deliver a blow to the long-ruling conservative party at national parliamentary elections on Sunday, following a wave of financial scandals, discontent over a stagnant economy and widespread disillusionment among young people.

Newly installed prime minister Shigeru Ishiba announced the election three days after he was sworn into the top job earlier this month. But the move may backfire, as opinion polls show the conservative Liberal Democratic Party heading for a drubbing with voters. The ruling coalition will possibly loses its majority, resulting in a weakened administration.
