Today, MPs have the opportunity to vote on whether to effectively end the use of anonymous companies in the UK’s overseas tax havens. Almost a year ago the Panama Papers demonstrated their importance, with more than half of the companies involved registered in the UK’s Overseas Territories. The proposed measure would give the UK-linked Overseas Territories, such as British Virgin Islands and Bermuda, until 2020 to introduce public registers of the true beneficial owners of companies, as the UK did last year.

Global Witness has spent many years exposing the dangers posed by the use of anonymous companies registered in the UK’s Overseas Territories by corrupt or criminal individuals, and has campaigned for transparency to bring this abuse to an end. In almost all of the major corruption cases we’ve investigated, anonymous companies have been at their heart.

So, on the eve of tomorrow’s vote, we’ve produced a run-down of our top 10 corruption cases run through anonymous companies in the Overseas Territories:

As all of these cases show, there is overwhelming evidence that anonymous companies in the Overseas Territories help fuel a staggering amount of corruption around the world, and this list is by no means comprehensive. In all of these cases, the secrecy provided by the anonymous companies was vital to the operation of these schemes.

Making the identities of the true, beneficial owners of companies public also helps businesses know who they’re doing business with, helps detect crime, saves money and helps prevent insecurity.

Tomorrow, all MPs should shine a long overdue light on these shady companies and vote to end anonymous companies in the UK’s overseas tax havens.
