MCA, which described Nazri Abdul Aziz as someone with an "inclination towards the opposition", has asked the tourism and culture minister to "control his mouth".
"As an Umno veteran, Nazri does not seem to know how to respect the BN coalition but instead, has repeatedly joined forces with DAP to slam MCA.
"Nazri should learn to control his mouth," said MCA publicity bureau deputy chairperson Lau Chin Kok in a statement today.
Lau was responding to Nazri who said MCA cannot oppose PAS' planned Act 355 rally as freedom of assembly was a fundamental right and suggested the Chinese party to organise its own counter-rally.
The rally on Feb 18 was meant to support an amendment to the Syariah Courts (Criminal Jurisdiction) Act 1965, or Act 355, which would increase the punishment limit that could be meted out under syariah law.
Lau reiterated that MCA was opposed to the rally as it could potentially undermine the harmony between Muslims and non-Muslims.
"Nazri should always remember that he is a member of BN which upholds moderation.
"If Nazri cannot accept this moderation and inclusiveness, he should leave BN or Umno.
Lau also questioned if Nazri's refusal to oppose the rally was due to a desire to maintain his good relationship with the opposition.
Meanwhile, Perkasa demanded that MCA president Liow Tiong Lai apologise for opposing the Act 355 rally, threatening to undermine his electoral campaign if he didn't do so.
"If Liow fails to apologise, Wira Perkasa Kelantan and Wira Perkasa Malaysia will declare Liow and his voters as enemies of Islam.
"We will campaign to ensure no Muslim voter in the 14th general election will vote for someone who opposes Islam," said the group's youth exco Burhanuddin Ruslan.
Burhanuddin, who also leads Perkasa's youth wing in Kelantan, said the movement might field its own independent candidate in Bentong. Liow is the MP for Bentong.- Mkini
