The Mossack Fonseca files show Khashoggi appeared as early as 1978, when he became president of the Panamanian company ISIS Overseas S.A. The documents reveal that Fonseca's clients included Sheikh Kamal Adham, Saudi Arabia's first intelligence chief (1963–79), brother-in-law of King Faisal, who was named by a US Senate committee as the CIA's “principal liaison for the entire the Middle East from the mid-1960s through 1979”. Adham controlled offshore companies involved in the B.C.C.I. banking scandal.
Former French budget minister Jérôme Cahuzac, who spearheaded a crackdown on tax fraud while in office, was a client of Mossack Fonseca and through them owned a Seychelles company named Cerman Group Limited, incorporated in 2009. When France investigated 2013 allegations by Mediapart that in 2000 Cahuzac had held undeclared assets in an account first in Switzerland, then Singapore, he resigned his cabinet post, protesting his innocence, but admitted a few months later that he indeed had hidden €600,000 in a UBS account and then moved it to keep it hidden, "while continuing to lead France's clampdown on tax evasion". The French Socialist Party unanimously voted to expel him a week later. On the heels of the April 2013 "Cahuzac affair", President Hollande created the parquet national financier (PNF), a judiciary investigation unit specializing in large-scale fraud and corruption investigations.

They became angry and did not believe the reporters when they said the president's family had a stake in the mine.

Businesswoman Ingibjörg Pálmadóttir and her husband Jón Ásgeir Jóhannesson have for several years financed their business dealings through a Panamanian company, Guru Invest, which owns shares in retailer Sports Direct through Rhapsody Investments (Europe), based in Luxembourg. Guru Invest paid around US$16 million to Glitnir bank after it crashed to cover the debt of Gaumur, one of Jón Ásgeir's companies, and loaned ISK 100 million to Jón Ásgeir's company Þú Blásól through an offshore company he owns named Jovita. Asked by journalists at Kjarninn where that money came from, Ingibjörg did not reply. Ingibjörg is the primary owner of the 365 media group, which owns the Icelandic news outlets Vísir.is, television channel Stöð 2 and radio stations Bylgjan, X-ið [is] and FM 957, none of which seem to be reporting this disclosure.
