KUALA LUMPUR — A Malaysian opposition party on Wednesday filed a civil suit against Prime Minister Najib Razak and indebted state fund 1Malaysia Development Berhad (1MDB), saying they had violated electoral rules and a new election should be held. 1MDB, whose advisory board is chaired by Najib, and which has debts of more than $11 billion, is under investigation for graft and financial mismanagement. The affair has triggered a political crisis for Najib. The Wall Street Journal reported in July that investigators looking into 1MDB found that nearly $700 million was deposited into Najib's accounts. Reuters has not verified the report. Najib has denied taking any money for personal gain, saying the allegations are part of a malicious campaign to force him from office. 1MDB has denied transferring funds to Najib and an interim government report found nothing suspicious. Last week, the national anti-graft agency said the funds in Najib's account were donations from the Middle East, and not from 1MDB. — Reuters
