Bersama co-leader Rafizi Ramli has cancelled his campaign engagements in Malacca tomorrow to return to Kuala Lumpur for police questioning over his allegations concerning the "corporate mafia" scandal and PKR vice-president R Ramanan.

The former Pandan MP said he had been summoned to Bukit Aman at 10am tomorrow (Nov 3) for questioning under Sections 500 and 505 of the Penal Code, which deal with criminal defamation and statements conducing to public mischief.

"I respect that the investigating officers are carrying out their duties as instructed.

"Therefore, I will return to Kuala Lumpur and cancel my campaign events in Malacca during the day on Tuesday to give my statement," said the former economy minister in a statement today.
