Plans to proceed with an anti-Icerd rally is a "mischievous political gimmick", says PKR president Anwar Ibrahim.

"We have held rallies to reject the Internal Security Act, to ask for clean and fair elections, and to reject cruelty.

"So if you want to rally, let it be for a reasonable purpose... Because this (anti-Icerd rally) is a mischievous political gimmick as the government has rejected the matter," Anwar was quoted as saying by Bernama.

Icerd is short for the International Convention on the Elimination of Racial Discrimination.

A group known as Ummah, backed by Umno and PAS, originally planned to hold a rally to protest ratification of the convention on Dec 8.

However, after Putrajaya pulled the plug on Icerd yesterday, the group has said it would proceed with the rally as a way to celebrate.

Ratifying Icerd has been a heated issue in Malaysia, with bumiputera groups opposing it as being against the Federal Constitution, which has special provisions for bumiputeras.
