Dhaka, Dec. 27 -- Former Malaysian Prime Minister Najib Razak was sentenced Friday to 15 years in prison and ordered to pay 13.5 billion ringgit ($3.3 billion) in fines and asset recovery after being found guilty in his largest corruption trial linked to the 1MDB state investment fund.

The High Court convicted the 72-year-old Najib on four counts of abuse of power and 21 charges of money laundering involving over $700 million channeled into his personal accounts from 1MDB. Justice Collin Lawrence Sequerah ruled that the sentences would run concurrently, meaning Najib will face another 15 years after completing his current term for an earlier 1MDB conviction.

Najib's lawyer, Mohamed Shafee Abdullah, said the court "made so many blunders"...
