Pakatan Rakyat parties are practicing double standard by attacking PAS president Abdul Hadi Awang for acting unilaterally on hudud when PKR did the same in the "Kajang Move", said a PAS leader.

DAP on Tuesday said it is cutting ties with Abdul Hadi for betraying Pakatan partners, but would maintain its relationship with PAS.

"Strangely, PKR turned its back on Pakatan on the 'Kajang Move'. Abdul Khalid Ibrahim was sacked as menteri besar (MB) without PAS' agreement, but this was not seen as treachery.

"And now, (DAP supremo) Lim Kit Siang is proposing collaborating with BN in the name of ' saving Malaysia '"?

"Isn't this a betrayal to the Pakatan common policy framework?" asked PAS ulama wing information chief Khairuddin Aman Razali in a statement.

The "Kajang Move" last February was a highly-cloaked plan by some PKR leaders to trigger a by-election in Kajang in order to pave the way for their de facto leader Anwar Ibrahim to replace Khalid as MB.

However, a spanner was thrown into the works when Anwar was convicted of sodomy days before the by-election, leaving PKR president and Anwar's wife Dr Wan Azizah Wan Ismail to contest the seat.

The "Kajang Move" widened cracks within Pakatan when Abdul Hadi was accused of rejecting Wan Azizah - PKR's sole candidate for the Selangor MB post to replace Khalid.

PKR deputy president Azmin Ali was eventually appointed MB by the palace.

DAP may lose votes from PAS members

Khairuddin is among PAS leaders who have retaliated against DAP's scathing attacks on Abdul Hadi.

The PAS president himself hit back today through an open letter to Muslims warning against those parroting Islamic terms just to counter hudud.

DAP secretary-general Lim Guan Eng had among others called Abdul Hadi  "dishonest", "dishonourable" and a " trojan horse for Umno ".

Although DAP stated that it would remain as PAS' ally, Khairuddin said this may not be enough to keep Pakatan intact.

"I worry that DAP's continued attacks, slander and derision of the PAS president and their strong opposition to the Kelantan Syariah Criminal Code would negate religious justifications for PAS members to work with and vote DAP in the election.

"I advise DAP to be more tactful and stop provoking PAS and its president, with hopes that Pakatan can still be a means to attack leakages, abuse of power, corruption and the BN administration’s failings," he said.

PAS had earlier justified working with DAP by saying that Islam allows tahaluf siyasi (political cooperation) with those with differing ideologies for the greater goal of upholding justice.

PAS has about a million members nationwide. In elections, PAS and DAP mutually use their cooperation to dispel perceptions of religious extremism and racial chauvinism.
