KUALA LUMPUR: Malaysian Prime Minister Mahathir vowed on Monday to investigate faults that may have been committed by the government toppled in last week’s general election, and said all ministries had been instructed not to destroy any documents. Mahathir announced that he would appoint a new anti-corruption commission chief and replace the attorney-general who had cleared former Prime Minister Najib Razak of wrongdoing in a multi-billion-dollar scandal linked to the 1MDB state fund. He also told a news conference that his government had a rough idea of the whereabouts of Malaysian financier Low Taek Jho, who is accused of links to a plot to siphon billions of dollars from the fund, 1Malaysia Development Berhad (1MDB). Najib set up 1MDB in 2009 and previously served as chairman of its advisory board. He and the fund have denied wrongdoing. Asked about other possible crimes, Mahathir said: “We cannot do everything at the same time at one go.”
