UMNO members should uphold the party's principles and abide by all its decisions.

In making the call, Perak Menteri Besar Datuk Seri Dr Zambry Abd Kadir said he was disappointed with the outburst by former Kuala Kangsar UMNO division head Datuk Ramly Zahari against Barisan Nasional (BN) candidate Datin Mastura Mohd Yazid in a local daily yesterday.

Zambry said the UMNO veteran should be aware of party principles which should be obeyed by every member.

"When the party makes a decision, it is incumbent on us to abide by it and I believe Datuk Ramly, a long-time politician should be better informed on party principles which should be upheld by members.

"I believe on that principle, he will hold unwavering loyalty on the party's decision and will assist the candidate and ensure the BN candidate won the Kuala Kangsar parliamentary by-election," he said.

He was speaking to reporters after handing over Hari Raya cakes to members of Perak security forces and uniformed personnel, in conjunction with Hari Raya Aidilfitri here today.

Zambry also advised party members to put aside whatever unhappiness and ensure BN retained the parliamentary seat.

In an interview, Ramly who was a former state exco member for 18 years, admitted being disappointed by Mastura who was cold to him.

Quoting a press report, Ramly claimed he was asked by Mastura's family to leave while attending a prayer session for Mastura's husband, Datuk Wan Mohammad Khail-il Wan Ahmad.

The Kuala Kangsar by-election was called following the death of Mastura's husband, Datuk Wan Mohammad Khairil Anuar Wan Ahmad in a helicopter crash in Sebuyau, Sarawak on May 5.

Polling for the four-cornered contest involving Mastura, Dr Najihatussalehah Ahmad (PAS), Prof Dr Ahmad Termizi (Parti Amanah Negara) and Independent candidate, Izat Bukhary Ismail Bukhary will be held on June 18.
