Refuting accusations of double standards, Malaysian Anti-Corruption Commission (MACC) chief Dzulkifli Ahmad reiterated his promise to net corrupt politicians and urged critics to be patient.

"There is no issue of 'pilih kasih' (favouritism), it's about timing. If we take action straightaway, then that's favouritism," he told reporters in Kuala Lumpur today.

Dzulkifli was responding to criticism over his previous statement that MACC would act against corrupt politicians after the next general election to avoid the arrests being used as political fodder.
