1Malaysia Development Bhd (1MDB) today rebutted claims by former prime minister Tun Dr Mahathir Mohamad saying that a cabinet paper was presented and approved for the issuance of a government guarantee RM5 billion sukuk by Terengganu Investment Authority (TIA). TIA was renamed 1MDB in 2009 after the federal government took over. In a statement today, 1MDB also said that the guarantee was not off-budget, and that Putrajaya was fully liable for the amount it had guaranteed. 1MDB also denied Dr Mahathir's claim that the RM2 billion loan it obtained from Ananda Krishnan was used to pay interest on its loans. It also questioned the "motivation" behind Dr Mahathir's allegations, which it said had numbers and figures changing every time.
