#29 Leaks
In December 2019, Distributed Denial of Secrets (DDoSecrets) published "#29 Leaks" in partnership with the Organized Crime and Corruption Reporting Project and more than 20 outlets in 18 countries.

The 450 gigabyte leak included emails, documents, faxes, and recordings of phone calls. Investigations revealed the firm ran a web of companies registered in Hong Kong, Cyprus, the British Virgin Islands and Pakistan, helped clients avoid anti-money laundering rules and had created banks in The Gambia in an attempt to create a tax haven. According to The Times, there was no evidence that Formations House did anything illegal but their investigation highlighted worrying vulnerabilities in the UK's defences against money laundering".

The release was compared to both the Panama Papers and the Paradise Papers. Belgian tax authorities initiated an investigation based on data from this leak and from the Cayman National Bank and Trust leak published by DDoSecrets the prior month. Politicians in Sweden and the UK, including anti-corruption chief John Penrose said the leak showed the need for reforms on company creation and registration.
