Umno supreme council member Tajuddin Abdul Rahman has discovered the reason behind Dr Mahathir Mohamad purportedly losing his “adab orang Melayu” (Malay etiquette).

He attributed the condition to the former premier having been “injected with DAP's blood.”

“Tun (Mahathir's) attitude does not reflect 'adab orang Melayu'. In fact, many Malays no longer possess this etiquette due to being influenced by DAP which is crude and rude.

“... They have been given DAP blood and that is the reason for their improper conduct,” he told Umno Online.

As for Mahathir's allegations against Prime Minister Najib Abdul Razak, the Umno leader warned the former premier that what goes around, comes around.

“Mahathir will receive his balasan (retribution) for all the slander he has hurled against Najib,” he added.

Tajuddin was responding to Mahathir claiming that the present Umno cannot be equated with the party which struggled for independence in the past.

Commenting on Mahathir praising Tunku Abdul Rahman, Tajuddin described this as nothing more than a political gimmick.

He said history would show that Mahathir was never fond of the first prime minister.

“Nobody can deny the enmity between Mahathir and Tunku... The one who kutip (picked) Mahathir was the late Tun Abdul Razak, the father of Najib.

“Mahathir should be grateful instead of deriding and embarrassing Najib around the world.

“Even if there are weaknesses in Najib's leadership, Mahathir should just reprimand (him). Mahathir's actions today have gone overboard,” he added.

Meanwhile, Tajuddin also reminded other races not to feel alarmed or challenged when issues concerning Malays are discussed.

He said non-Malays should not be fearful as Umno's 60-year rule proved that it is fair and does not oppress other races.
