Dr Mahathir Mohamad admitted that Prime Minister Najib Abdul Razak has "at the moment", got the better of him, but if fair elections are carried out, the latter's administration can be overthrown.

In a recent exclusive interview with Australia's SBS World News, the former premier also said that at 91-years-old, he is too old to contest in the elections and to be opportunistic and have "ambitions" behind his move of criticising Najib and his former party Umno.

When journalist Jarni Blakkarly asked him whether he expected to return to active politics, 14 years after he stepped down as PM, Mahathir replied in the negative.

"At the time when I stepped down I thought I would be having my retirement, resting and enjoying life, but it seems that it is not going to be like that"...
