Malaysian Prime Minister Mahathir Mohamad has accepted the resignation of the central bank governor, the latest in a string of departures as the 92-year-old leader purges top officials seen as close to the scandal-plagued previous government. The move comes after finance minister, Lim Guan Eng, raised questions about the central bank’s purchase of land from Najib Razak’s government. Lim said Najib had used money raised from a land sale to pay off some of the debts of 1MDB, the state investment fund that’s been mired in a corruption scandal. Malaysia’s newly appointed attorney general Tommy Thomas said on Wednesday there would be “no cover ups” as he promised to institute criminal and civil action over a graft scandal at 1MDB.
