Malaysian opposition leader and former deputy prime minister Ahmad Zahid Hamidi has pleaded not guilty to 45 charges of abuse of power, corruption and money laundering.
He was charged on Friday with eight counts of abuse of power, 10 counts of criminal breach of trust and 27 counts of money laundering.
The opposition leader was released on a two-million-ringgit ($A676,000) bail and instructed to surrender his passport by Judge Azura Alwi.
Hundreds of Zahid supporters were seen outside Kuala Lumpur court as he arrived surrounded by family on Friday morning.
Ex-premier Najib Razak, who is facing similar charges, was seen leaving the court earlier on Friday and told reporters "I am here to give support to an old friend."

Zahid's arrest by Malaysia's anti-graft agency on Thursday came following investigations into allegations of abuse of power, criminal breach of trust and money-laundering involving funds from a family-linked foundation.
He is accused of using 800,000 ringgit ($A$270,500) of the foundation's funds to pay off credit card bills.
Zahid, who heads the opposition party United Malays National Organisation (UNMO), is the latest prominent figure in Malaysian politics to be arrested following Najib and his wife Rosmah Mansor.
Zahid was deputy prime minister under Najib, whose government was ousted in elections in May amid widespread anger over a corruption scandal that engulfed the state fund 1MDB.
The state fund is the subject of a sweeping international investigation by at least six countries - including the US, Singapore and Switzerland - over alleged money laundering and graft by high-level officials.
The scandal became public in 2015, when the Wall Street Journal reported that Malaysian investigators had traced almost $US700 million that had been deposited into Najib's personal bank account via banks, companies and agencies linked to 1MDB.
Zahid's hearing has been set for December 14, when his case will be transferred to the high court.
