Disheartened over the feud between Prime Minister Najib Abdul Razak and former premier Dr Mahathir Mohamad, Shahidan Kassim has urged the two to focus on the nation's development.

The minister in the Prime Minister's Department has also decided to broker peace between the two camps.

Shahidan said he would meet with both Mahathir and Najib to discuss this.

"I will meet up with Tun (Mahathir) in the soonest possible time and ask him for guidance most probably on Wednesday," he said.

"I feel absolutely sad if this drags on. The bigger agenda here is to develop the country and rectify what is wrong.

"I will try my best to calm the situation. To me, this is not right and should not have happened," he told reporters today.

Shahidan said the leaders should be seen as being more focused on addressing the problems the country is currently facing from the outside world.

Adding that there is no point in attacking each other, he warned that there would only be losers and no winners.

"There are teams (supporters) who want to beat the other (team), but then again how long can one keep doing that?

"If everyone starts fighting, who will benefit? No one wins. Things like this can be avoided if everyone stays calm," he stressed.

Shahidan also quipped that politicians should hit out at others during elections, as it would have greater impact.

Mahathir has been openly critical of the Najib administration and its policies as well as the prime minister's debt-ridden brainchild 1Malaysia Development Berhad (1MDB).

The former premier's close associates such as ex-finance minister Daim Zainuddin have also been firing salvos.

Though Najib has refrained from removing his gloves, eyebrows were raised when the Umno-linked media started to provide space for PKR and opposition leader Anwar Ibrahim to attack Daim.
