Admitting that the quota system for diesel supply is imperfect, Domestic Trade and Consumer Affairs Minister Mohd Shafie Apdal said hopefully a decision will be reached on the shortage next week.

"I know the quota system has its defects," he said during a press conference at the Parliament lobby today after attending a meeting, chaired by Deputy Prime Minister Najib Abdul Razak, on the issue.

"Hopefully, a decision will be reached next week," he added, in reference to the cabinet discussing the issue during its weekly meet on Wednesday.

Shafie blamed the lack of enforcement and smuggling as the reasons behind the shortage but repeatedly assured that the public will receive sufficient supply.

Working with ACA, police

According to him, the police and the Anti-Corruption Agency (ACA) will cooperate with his ministry to clamp down on smuggling activities.

He also denied allegations that his ministry had a hand in the illegal siphoning of diesel.

As for the quota system and subsidy, Shafie said it will continue to be implemented and that the authorities will 'ensure that supply is sufficient according to needs'.

Yesterday, the minister came under fire from opposition parliamentarians, who called for his resignation in the wake of the diesel crisis.

The shortage has affected lorry and bus companies nationwide.
