Former Malaysian Prime Minister Najib Razak pleaded not guilty Wednesday to three new money-laundering charges related to the alleged multibillion-dollar looting of a state investment fund that led to his stunning electoral defeat three months ago.

Najib spoke softly as he entered his plea in the High Court. He has previously accused Malaysia's new government of seeking political vengeance and vowed to clear his name in his trial.

Najib, 65, had pleaded not guilty to abuse of power and three counts of criminal breach of trust last month.

All of the charges against him involve the transfer of 42 million ringgit ($10.3 million) into his bank accounts from SRC International, a former unit of the 1MDB fund that international investigators say was looted of billions by Najib's associates.

Abuse of power and breach of trust carry a maximum penalty of 20 years in prison for each charge. Each money-laundering count carries a penalty of up to 15 years in prison and a fine of not less than five times the sum laundered.

Najib set up 1MDB when he took power in 2009 for the stated purpose of promoting economic development, but the fund amassed billions in debts and is being investigated in the US and several other countries for alleged cross-border embezzlement and money laundering.

After leaked documents exposed the scandal, Najib sacked critics in his government, muzzled the media and quashed investigations. Public anger led to the defeat of Najib's long-ruling coalition in May 9 elections and ushered in the first change of power since Malaysia gained independence from Britain in 1957.

The new government reopened the investigations stifled under Najib's rule and barred him and his wife from leaving the country. Police also seized jewelry and valuables valued at more than 1.1 billion ringgit ($270.2 million) from properties linked to Najib.
