[1] In January 2017, reformists started working with moderates and supporters of Hassan Rouhani to compile a shared electoral list of candidates for City Council of Tehran.

[2] In April 2017, the Moderation and Development Party joined the Reformists' Supreme Council for Policymaking,[3] the body responsible for picking the candidates included in the list.

Some reform-minded non-partisans were also expected to feature in the list, including whistleblower Yashar Soltani, social activists Leila Arshad and Ameneh Shirafkan, and Taraneh Yalda, a cityplanner.
