Nibong Tebal MP Tan Tee Beng today formally announced his resignation from PKR and is now an independent.

However, he refused to confirm if he would be an ally to Barisan Nasional.

The announcement was made during a press conference in Ampang, Selangor, accompanied former PKR secretary-general Salehudin Hashim who has also recently resigned from the party.

In a related development, Kulim Bandar Bharu MP Zulkifli Noordin, when contacted, denied news reports that he would announce his resignation today.

Both Tan and Zulkifli were scheduled to be hauled up by the PKR disciplinary board this month, among others, for attacking Pakatan Rakyat leaders.

Zulkifli told Malaysiakini that he will not attend the scheduled hearing this afternoon because the party has yet to reply his Feb 16 letter, which made several complaints about the proceedings.

"Until today, they have yet to reply. So how can I attend the hearing?" he asked.

Previously, the Tan and Zulkifli were rumoured to be among several disgruntled PKR MPs who are keen on following the footsteps of Bayan Baru MP Zahrain Hashim.

Zahrain left the party after citing a loss of confidence in Penang chief minister Lim Guan Eng. He also claims that the DAP-led government was sidelining PKR.

Incidently, Zahrain was also accompanied by Salehudin during his press conference to announce his resignation from the PKR on February 12.
