Prime Minister Najib Abdul Razak has been urged to lead by example on his reminder to civil servants this morning not to take what rightfully belongs to the people.

"Our message to Najib is practise what you preach. The best way to stem graft in the public sector is leadership by example," said Center to Combat Corruption & Cronyism (C4) founder Cynthia Gabriel.

She said Najib could return the RM42 million that went into his personal bank account, allegedly from SRC International Sdn Bhd, the former subsidiary of 1MDB.
