1MDB TRIAL | An MACC officer has denied “improvising” his testimony backing Najib Abdul Razak's defence against the RM2.27 billion 1MDB abuse of power and money laundering trial.

However, defence witness Fikri Ab Rahim admitted that he did “add on” to his testimony today from the one he previously gave in a separate RM42 million graft case against the former prime minister.
