Dubbed the Pandora Papers, the landmark probe, published on Sunday, was conducted by the International Consortium of Investigative Journalists (ICIJ) – an ensemble of 600 journalists from 150 media outlets in 117 countries.
In addition to the politicians and heads of states, singer Shakira and former Indian cricket captain Sachin Tendulkar are among celebrities and sport stars named in the investigation.
Here is a look at some of those names:
Jordan’s King Abdullah II amassed about $100m worth of property in the United States and United Kingdom through secret companies. They were purchased between 2003 and 2017 via firms registered in tax havens and include properties in Malibu, southern California, and Washington and London.
DLA Piper, a London law office representing Abdullah, told the ICIJ that he had “not at any point misused public monies or made any use whatsoever of the proceeds of aid or assistance intended for public use”.
The royal palace said in a statement on Monday that the king’s ownership of private properties in the UK and the US was not a secret, adding that privacy and security reasons were behind not disclosing it.
The leaked files also showed that in neighbouring Lebanon, top political and financial figures have embraced offshore havens.
These include Prime Minister Najib Mikati, his predecessor Hassan Diab, Riad Salameh, the governor of Lebanon’s central bank – currently under investigation in France for alleged money laundering – and former minister of state and the chairman of Al Mawarid Bank Marwan Kheireddine.
The consortium said Kheireddine and Diab did not respond to requests for comment while Salameh said he declares his assets.
Mikati’s son, Maher, told the ICIJ that owning real estate through offshore entities offers more “flexibility” when it comes to renting, inheritance planning, and “potential tax advantages”.
He told Al Jazeera that: “Using offshore entities could be considered as forms of tax evasion for US and EU nationals but this is not the case for Lebanese nationals.”
The Pandora Papers show that prominent members of Pakistani Prime Minister Imran Khan’s government, donors to his party and family members of the country’s powerful military generals moved millions of dollars of wealth through offshore companies.
Two members of Khan’s cabinet – Water Resources Minister Moonis Elahi and Finance Minister Shaukat Tarin – were prominent in the leaks, alongside more than 700 other Pakistani citizens.
The consortium said the documents contained no suggestion that Khan himself – who rose to power in 2018 on the back of promises to arrest Pakistan’s “corrupt” political elites – owns offshore companies.
The report said Czech PM Andrej Babis moved $22m through offshore companies to buy an estate on the French Riviera in 2009 while keeping his ownership secret.
Babis, speaking on Sunday in a TV debate ahead of October 8-9 elections, denied wrongdoing and said “the money left a Czech bank, was taxed, it was my money, and returned to a Czech bank”.
The investigation found Azerbaijani President Ilham Aliyev and his family have secretly been involved in British property deals worth more than 400 million pounds ($542m), according to the BBC.
The files show how the family bought 17 properties, including a 33-million pound ($44.8m) office block in London for the president’s 11-year-old son.
The Guardian newspaper said the files provided evidence that the US state of South Dakota rivalled opaque jurisdictions in Europe and the Caribbean for financial secrecy.
The documents reveal almost $360bn in customer assets are sitting in trusts in South Dakota, some of it tied to foreign individuals and companies accused of human rights abuses and other wrongdoing, it said.
Kenya’s President Uhuru Kenyatta and six members of his family have been linked to 13 offshore companies, according to the documents.
The Kenyattas’ offshore investments included a company with stocks and bonds worth $30m, the BBC reported.
Tony Blair, the UK prime minister from 1997 to 2007, became the owner of an $8.8m Victorian building in 2017 by buying a British Virgin Islands company that held the property, and the building now hosts the law firm of his wife, Cherie Blair, according to the investigation.
The two bought the company from the family of Bahrain’s industry and tourism minister, Zayed bin Rashid al-Zayani.
Buying the company shares instead of the London building saved the Blairs more than $400,000 in property taxes, the investigation found.
The Blairs and the al-Zayanis both said they did not initially know the other party was involved in the deal, the probe found. A lawyer for the al-Zayanis said they complied with UK laws.
The Washington Post said Russian woman Svetlana Krivonogikh became the owner of a Monaco apartment via an offshore company incorporated on the Caribbean island of Tortola in April 2003, just weeks after she gave birth to a girl.
At the time, she was in a secret, years-long relationship with Russian President Vladimir Putin, the Post said, citing Russian investigative outlet Proekt.
The report also revealed Putin’s image-maker and chief executive of Russia’s leading TV station, Konstantin Ernst, got a discount to buy and develop Soviet-era cinemas and surrounding property in Moscow after he directed the 2014 Winter Olympics in Sochi.
Ernst told the organisation the deal was not secret and denied suggestions he was given special treatment.
