In 2009 the society became the secretariat of two all-party parliamentary groups (APPGs), for Transatlantic and International Security, chaired by Gisela Stuart, and for Homeland Security, chaired by Bernard Jenkin. A transparency requirement upon non-profit organisations acting as secretariat at that time was that they must reveal any corporate donors who gave £5,000 or more to the organisation. In 2014, following a query, the society refused to disclose this information and resigned its position, so as to comply with the Rules. The Parliamentary Commissioner for Standards, Kathryn Hudson, upheld a complaint against these APPGs, but noted the society had already resigned, and its non-provision of secretariat services therefore "appears to have taken effect" as the Rules intended. The case was closed with no further action taken and the APPGs themselves dissolved with the dissolution of Parliament in March 2015. The APPG Rules were subsequently changed so only non-profit organisations providing services to APPGs of more than £12,500 in value need to declare corporate donors.
