This Annual Review provides an overview of the activities and achievements carried out by REDRESS from April 2020 to March 2021, with coverage of developments up until the date of printing in select areas. Among our successes this year we continued our efforts to end state hostage-taking, particularly in relation to the case of British-Iranian Nazanin Zaghari-Ratcliffe. We also joined the successful campaign to amend the Overseas Operations Act, preventing an effective amnesty for UK service personnel who commit international crimes such as torture. Additionally, we started a new project to ensure the effective use of Magnitsky Sanctions in the UK, a new tool for those challenging torture around the world. Meanwhile Sudan took historic steps to eradicate torture within the country by ratifying two major international human rights treaties, something REDRESS has long advocated for. We have challenged the use of enforced disappearance as a form of torture, as well as challenged discriminatory torture through projects on reparation for sexual violence in conflict and research on LGBT+ torture in Africa.
