Former Malaysian Prime Minister Najib Razak says he shouldn't be blamed for the multibillion-dollar 1MDB scandal, and declares he knows nothing about money from the state fund appearing in his personal account.

He does, though, have explanations for the vast sums of cash, luxury handbags and jewelry recently seized from his homes by the Malaysian authorities.

Speaking to Reuters in his first sit-down interview since his shock May 9 election defeat, Najib said his advisers and the management and board of 1Malaysia Development Berhad (1MDB), had wrongly kept the alleged embezzlement of funds a secret from him.
