OPS Manis, launched to ensure sufficient sugar supply, will be extended to June 30, says Datuk Seri Salahuddin Ayub.
The punishments on three serious offences have also been heightened, added the Domestic Trade and Cost of Living Minister.
He said those who were caught hoarding or marking up sugar prices would be blacklisted or have their licences revoked.
“We received complaints that some stores demanded consumers to also purchase premium sugar packets. This is an offence. We will take stern action against those who break the law,” he said.
He added that seven cases of manipulating sugar sales were uncovered, with five cases in Kedah, one in Kelantan and another in Terengganu.
