Malaysian Prime Minister Mahathir Mohamad said on Tuesday he is confident that prosecutors will soon have a strong case to charge former prime minister Najib Razak over graft claims at state fund 1MDB. The Malaysian Anti-Corruption Commission (MACC) found evidence in late 2015 that RM$42 million (S$14.2 million) was transferred from a former subsidiary of state fund 1MDB into an account of then Prime Minister Najib, but its recommendation for further investigation was rejected by the attorney-general, a member of a panel that reviewed the commission’s case files told Reuters. The former director of MACC, Abdul Razak Idris, has lodged a complaint against Najib, alleging he personally blocked an investigation into the $3.2bn 1MDB scandal.
