KUALA LUMPUR - Tun Dr Mahathir Mohamad will not work with the opposition, despite his recent attacks against Prime Minister Datuk Seri Najib Tun Razak.
"No, I'm not working with anyone to bring down Najib, certainly not the opposition.
"The problem is within Umno itself," the former premier told reporters at the Putra World Trade Centre on Sunday.
Dr Mahathir, however, said that Naib should understand the sentiments of the people and it was best for him to resign as Prime Minister.
"One has to remember the results of the 13th general election. Najib's performance was worse than Pak Lah's (Tun Abdullah Ahmad Badawi).
He added that Najib was not receiving support, despite the number of people who have pledged their support.
"Believe me, he is not getting the support that he needs," Dr Mahathir said.
On Saturday, DAP adviser Lim Kit Siang had said that he was ready to put aside past problems and work with Dr Mahathir if that is what it takes to save the country.
"For this formidable task, we must be prepared to put our differences in the past to one side and concentrate all our energies on one common agenda, to save Malaysia from all centrifugal forces to tear the country asunder.
"On this agenda, I am prepared even to work with Tun Mahathir to 'Save Malaysia'," Lim had said in a transcript of a speech to Malaysian students in Egypt published on his blog.
Lim was referring to the "Save Malaysia" coalition, which he had first spoken about last month.
