Prime Minister Najib Abdul Razak has launched a broadside on PKR, saying the party failed to understand the Selangor state constitution when it disputed the power of the sultan over the appointment of the menteri besar.

He said the party was also willing to be in cahoots with DAP just to fulfil its aim of getting PKR president Dr Wan Azizah Wan Ismail appointed as the new Selangor menteri besar.

"Just look at the antics of PKR in Selangor... They don't understand the constitution and the position of the royal rulers.    

"The obvious is one thing, they don't understand the implicit too but I understand. That is why they are in cahoots with DAP, as though giving an ultimatum to the Sultan," he was quoted as saying by Bernama .

Najib said this in his winding-up speech of the debate at the Pekan Umno division delegates' meeting in Pahang.

Najib 'pantang' hearing about Dyana

In view of this, the prime minister said Umno members must explain to their children about the repercussions should Umno and BN be removed from power.

"Look at the situation now, if we have no power, what will happen to the institution of Malay rulers, what will happen to Islam, what will happen to the Malays.

"There must never be the children of Umno (members) not joining the party," he added.

Training his guns on DAP's Dyana Sofya Mohd Daud, Najib said he loathed (pantang) to hear about people like her.

"Mother and father are Umno people, but the daughter joins DAP. So we must 'Umnokan' our children," he added.

If this is not done, Najib, who is also Umno president, warned that the exceptional performance of Umno in defending the Malays, Islam and the rulers would not be guaranteed.

The prime minister also reprimanded civil servants whose children disliked the government but at the same time expected assistance.    

Dyana Sofya was the DAP candidate for the Teluk Intan by-election in May. She was defeated by Gerakan president Mah Siew Keong.
