The Iranian presidential election debates of 2013 was held from 31 May to 7 June. For the 2013 election, the IRIB has approved three televised debates with all candidates, different from last election's format which was person-by-person. For each question, one candidate was chosen randomly to give his response. Then, other candidates shared their ideas. The eight candidates have explained their cultural and political plans during debates. The debates were focused on such issues as the economy, foreign policy, and Iran’s comprehensive talks with the P5+1 group (United Kingdom, China, France, Russia and the United States, plus Germany) over the country’s nuclear energy program. More than 45,000,000 people world-wide watched the debates according to IRIB.
