Public Accounts Committee chief Hasan Arifin has denied that he is facing a boycott by opposition and BN committee members.

"There is no boycott," Hasan told reporters when met after the PAC meeting today.

Today's meeting was not attended by four out of five opposition lawmakers, and two from BN.

The missing opposition MPs are Petaling Jaya Utara MP Tony Pua, Teluk Kemang MP Kamarul Baharin Abbas, Selayang MP William Leong, and Kota Bharu MP Takiyuddin Hassan.

Takiyuddin did not attend as he was in the House to listen to Health Minister Dr S Subramaniam speak about yesterday's tragic hospital fire in Johor Bahru.

The missing BN MPs meanwhile were Kulim Bandar Baru MP Aziz Sheikh Fadzir, and Tanjung Piai MP Wee Jeck Seng.

Sources told Malaysiakini that Aziz had not been attending the PAC meetings since after its 1MDB report was tabled in April.

Similarly, Pua, Leong and Kamarul have also been skipping meetings since then.

Those familiar with the matter said Aziz was opposed to Hasan unilaterally editing the 1MDB report, after it had been agreed on collectively.

This is in reference to Hasan deleting a sentence which stated that Bank Negara had informed the PAC that Good Star Ltd was owned by an individual not linked to the PetroSaudi group.

It has since been established Good Star is owned by Penang-born tycoon Jho Low, whom US authorities claim misappropriated 1MDB monies.

The company had received US$1.03 billion of 1MDB funds meant for a joint venture with PetroSaudi International.

Malaysiakini has contacted Aziz for a response to this allegation.

When asked about Aziz's absence, Hasan did not appear to know how to respond.

"We will have to check how many times he did not come," he said.

Hasan also asked reporters if Aziz had said that he was boycotting the PAC before saying he would issue a press statement.

As for Pua's absence, Hasan said: "Biasa la dia (that is normal of him)."

In his statement later, Hasan reiterated that there was no boycott.

"The boycott issue does not arise as opposition members attended, and those who did not attend informed that there were unavoidable reasons."

He also said that PAC meetings since April had met the minimum quorum of three members including the chairperson.
