Speculation has been rife that the RM2.6 billion deposited into Prime Minister Najib Abdul Razak’s personal bank accounts was used for campaign purposes in the last general election.

"How do you know RM2.6 billion was used for the general election? He (Najib) never said that,” Tajuddin Abdul Rahman told Malaysiakini yesterday.
