The opposition Pakatan Rakyat coalition is putting a brave face on a spate of defections and infighting that has hit just as its leader Anwar Ibrahim fights sodomy charges that could end his career.

Three parliamentarians and a top party official quit Anwar's PKR in recent weeks, in a boost for the long-serving BN government which was humbled by its worst ever performance in 2008 elections.

Senior figures in Pakatan say an exodus which has included many more lower-ranking members is a necessary "cleansing" after the polls, which saw some untested candidates sweep to surprise victories.

NONE"Before the 2008 general elections, Keadilan (PKR) faced difficulties in finding candidates and we took whoever we could get, with the consequence that some of them were not up to the mark," party vice-president Sivarasa Rasiah (left in photo) told AFP.

"It's better they leave now rather than weaken us later at a more critical time near or at the next general election."

But analysts say that party-hopping is nudging the government towards regaining the crucial two-thirds parliamentary majority which it lost in 2008, depriving it of the right to amend the constitution in its favour.

After stunning success in the 2008 polls, which also netted the opposition control of five states, Anwar plotted to seize power by securing mass defections from the BN government.

But it was the BN that ended up drawing defectors, wresting control of Perak when three state assemblymen jumped ship in early 2009.

Last month, Bayan Baru MP Zahrain Hashim left the party, followed last Sunday by former Penang deputy chief minister and senior PKR member Mohammad Fairus Khairuddin.

Prime Minister Najib Razak welcomed the defection of Mohammad Fairus, who stood down as deputy chief minister amid graft allegations, saying that PKR members have "lost confidence" in their leaders.

On Monday, another Penang lawmaker, Nibong Tebal MP Tan Tee Beng, announced his departure and declared himself an independent. Today, a third lawmaker, Bagan Serai MP Mohsin Fadzli Samsuri announced his resignation from the party.

Anwar has also struggled to quell ideological rows among his alliance partners over issues including a ban on alcohol for majority Muslims and non-Muslims being barred from using the word 'Allah' as a translation for God.

BN seeks to reclaim two-thirds majority

Veteran opposition lawmaker Lim Kit Siang said it was all part of "a long-needed self-cleansing process which, however painful and agonising, is necessary to restore public confidence".

That process is taking place against the backdrop of Anwar's trial, which began last month, on new sodomy charges that could see him jailed for up to 20 years, and which he says are a political conspiracy.

azlanThe BN only needs seven more seats to reclaim its two-thirds majority in the 222-seat parliament, and Mohammad Agus Yusoff from University Kebangsaan Malaysia said more defections were likely.

If Pakatan loses its one-third hold on parliament, it would have "a huge impact" because the government would once again be able to amend the constitution and change election rules to boost its own position, he said.

Political analyst Shahruddin Badarudin said the defectors were often disgruntled "because they are not getting any benefits, contracts or payoffs from the opposition state governments, who want to be transparent and clean."

"The opposition is already aware of which other lawmakers are expected to defect," he said.

"The issue is now how to get them out and consolidate the party so that a situation that can be managed does not get out of hand."
