Will countries step up to agree ambitious new global standards on beneficial ownership? The United Nations Special session of the General Assembly against corruption (UNGASS), on 2–4 June 2021, is an opportunity to do just that. To inform the ongoing negotiations around a political declaration on corruption, Transparency International launched a petition in December 2020. The petition, submitted to UNGASS on 24 February 2021, called for “an end to the abuse of anonymous companies and other legal vehicles that facilitate cross-border corruption and other crimes.”
