KUALA LUMPUR: Malaysia's extraordinary 1MDB corruption scandal allegedly saw top officials loot billions from a state fund and go on a worldwide spending spree - buying up super-yachts, paintings by Van Gogh and Monet, and financing a Hollywood blockbuster.
The controversy has had a huge impact in Malaysia, contributing to the downfall of a coalition that had ruled the country since its independence from Britain in 1957.
Malaysia's disgraced former leader Najib Razak goes on trial Wednesday (Apr 2) over the scandal, facing seven charges of corruption and money laundering over the alleged theft of some 42 million ringgit (US$10.3 million) from SRC International, a former 1MDB unit.
It is only a fraction of the money allegedly stolen from 1MDB - and only the first of several trials over Najib's alleged involvement in the looting of the fund. Hundreds of millions of dollars are believed to have ended up in Najib's accounts alone.
Here is a look back at the saga:
WHAT IS 1MDB?
1Malaysia Development Berhad (1MDB) is a state investment fund which Najib Razak launched in 2009 shortly after becoming Malaysia's prime minister.
Its portfolio has included power plants and other energy assets in Malaysia and the Middle East, and real estate in Kuala Lumpur.
The fund was closely overseen by Najib.
Whistle-blowers say Low Taek Jho - commonly known as Jho Low, a jet-setting Malaysian financier close to Najib but with no official positions - helped set up 1MDB and made key financial decisions.
Concerns escalated in 2014 as 1MDB slid into an US$11-billion debt hole, and intensifying public scrutiny led to a string of revelations concerning missing funds.
The issue exploded in July 2015 when The Wall Street Journal published documents showing Najib received at least US$681 million in payments to his personal bank accounts.
The US Department of Justice launched a probe due to claims that stolen Malaysian public money was laundered through the US financial system, and filed lawsuits seeking some US$1.7 billion in assets allegedly purchased with the cash.
In its civil suits, the department said more than US$$4.5 billion was stolen from 1MDB by high-level officials at the fund and their associates between 2009 and 2015.
Tens of millions of dollars in stolen money was used in 2012 by Najib's stepson Riza Aziz, an aspiring film producer, to fund the Hollywood film The Wolf of Wall Street, starring Leonardo DiCaprio.
Hundreds of millions were used, mainly by Riza and Low, to purchase high-end real estate in Beverly Hills, New York and London, a Monet painting for US $35 million, a Van Gogh for US$5.5 million, a US$35 million Bombardier jet, a US$100-million stake in EMI Music Publishing, and a US$250 million yacht.
The US Department of Justice believes US$4.5 billion in total was looted from 1MDB.
Najib desperately sought to contain the scandal, targeting critics and introducing repressive laws, but the allegations hit the popularity of his long-ruling coalition and contributed to its shock election loss in May.
A new government headed by veteran politician Mahathir Mohamad, who is 93 and in his second stint as premier, came to office on a wave of public anger, and has reopened investigations.
Najib has since been hit with dozens of charges. He denies any wrongdoing.
Malaysia has also charged Wall Street titan Goldman Sachs over the scandal, alleging the bank and its former employees stole billions of dollars from 1MDB.
Goldman units and two ex-bankers are accused of misappropriating US$2.7 billion, bribing officials and giving false statements in relation to bond issues they arranged for the fund.
They are accused - along with Low and a former 1MDB employee - of misappropriating US$2.7 billion from the bond issues, bribing officials to ensure they were selected to carry out the work and giving false statements to investors.
The two ex-bankers named in the charges are Tim Leissner, who worked as Southeast Asia chairman and managing director at Goldman, and Ng Chong Hwa, a managing director at the firm.
The bank has vowed to fight the charges.
