He said the move to write and spread the letter proved that certain quarters, especially Umno haters, were worried about the strong solidarity among Umno leaders and members.

“Umno has grown stronger and more solid now because those who were not loyal to the party quit and formed another party. When they quit, there were no more wolves in sheep’s clothing in Umno. Now Umno is left only with members who are 100% loyal to Datuk Seri Najib, strongly united because we now only have one team.”

He said this after presenting school aid to 6,500 students in the Bera constituency, as well as excellence awards to those who excelled in their Ujian Pencapaian Sekolah Rendah (UPSR) 2016, here today.

Ismail Sabri also expressed confidence that Umno members would not fall for the allegations in the poison-pen letter as they were wise enough to reject information detrimental to Umno’s solidarity.

In Sintok, another Umno Supreme Council member Shahidan Kassim said the poison-pen letter, which was clearly aimed at creating tension between Zahid and Najib would not be able to shake, let alone destabilise the party.

He said this was because it was not the first time Umno faced this kind of challenge.

“I hope those responsible for writing the poison-pen letter will repent immediately. May Allah forgive their sins,” he said after opening the seminar to discuss the National Security Council Act for universal harmony here today.

The poison-pen letter with the falsified signature of Zahid went viral over social media recently.

The letter contained, among others, a demand for Najib’s immediate resignation from the government.

However, too many errors were found in the letter, including in the format, letter head and the positions of the leaders mentioned.
