Prime Minister Najib Abdul Razak, after being repeatedly accused by ex-prime minister Dr Mahathir Mohamad of deviating from Umno's struggle, admitted that his fight is no longer the same as the past.

However, Najib, referring to Mahathir as a "91-year-old man" without naming him, indicated that this was for good reasons.

"It is true that the struggle of the past and now are different.

"Last time, he, who is now 91 years old, struggled for independence.

"Now, I am struggling for the nation's development," Najib said in a blog posting today.
