Defence lawyers are sceptical of the prosecution's ability to nail Najib Abdul Razak on money laundering charges in his RM2.28 billion 1MDB trial.

Commenting on the prosecution's opening statement, lead defence counsel Muhammad Shafee Abdullah claimed that it does not matter where the money the former premier spent came from.

Instead, Shafee stressed, what matters in the case is whether Najib knew that the funds that ended up in his account originated from 1MDB.
