A former aide to PKR president-designate Anwar Ibrahim has urged the latter to come down hard on those making accusations of a high-level plot.
Ezam Mohd Noor said there should be "no compromise" towards those who make such statements as it could be detrimental to both the government and nation.
He was referring to PKR Kapar MP Abdullah Sani Abdul Hamid's allegation that Prime Minister Dr Mahathir Mohamad and Daim Zainuddin are attempting to prevent Anwar from becoming the next prime minister.
Abdullah Sani, who is aligned to former Pandan MP Rafizi Ramli, claimed that the pair is colluding with PKR deputy president Azmin Ali to achieve this objective.
Rafizi is contesting against Azmin for the PKR number two post.
Ezam cautioned that negative comments against the government from an MP with the ruling coalition does not augur well in terms of image.
"However, several statements of late do not only affect the image but the stability and the economy of the country as they touch on several things which should have been avoided being spoken about so openly and casually, without any proof.
"The statement concerning Daim would definitely affect the nation as he is the chairperson of the Council of Eminent Persons (CEP) elected by the prime minister.
“No one can deny that the CEP, comprising influential figures such as Zeti (Akhtar Aziz), Hassan Merican, Robert Kuok and Jomo Kwame Sundaram, and Daim himself, has had a positive impact on the stability and economy of the country, especially in the early stages of the formation of the new government,” he added in a statement.
Furthermore, Ezam said the allegation concerned the post of the prime minister.
"The post of prime minister is not just any other (government) post. Any statement concerning it must be made carefully, what more when it (the statement) comes from an MP from the government side.
"If the allegation was made by an opposition MP, the implications would be different. But from a government-side MP, it has much larger implications to the nation.
"The excitement of campaigning for party posts should not be made a license to do things which can affect the country, so stop it," he added.
Therefore, Ezam said Anwar, who is also Harapan de facto leader, must be firm in "righting this situation".
"As the former number two in this country and finance minister, he would surely understand the question of the nation's stability and its economy.
"If we sincerely want to save the country, and place the interest of the nation over other interests, there should be no compromise on such destructive elements," he added.
Directing his focus towards Rafizi, he said the PKR deputy president candidate should take more responsibility in curbing this "as the head of the group that is campaigning".
Stating that he was the one who brought Rafizi into PKR after recognising his potential then, Ezam said he nonetheless "disagreed with several statements and actions made by him lately".
