DAP secretary-general MP Lim Guan Eng has denounced the 15 sen increase in petrol prices, and the partial withdrawal of cooking oil subsidies.

Lim said this made a "mockery" of the RM200 increase in BR1M cash vouchers announced by Prime Minister Najib Razak during his Budget 2017 speech last week.

The hike was "unjustified and completely unsympathetic" to the economic hardships of ordinary Malaysians, said Lim, who is also Penang chief minister and Bagan MP.

"This is a classic case of giving with the right hand but taking back much more with the left hand," he said.
