The Arab Spring, which was initiated by the events taking place at the end of 2010 in Tunisia, gripped much of the Middle East, including Iran. However, demonstration of support for revolutionaries in Tunisia and Egypt, which began in Iran in February 2011 were doomed from the start to failure. On the one hand, the regime had taken all possible measures to prevent development of similar scenario, as in Tunisia and Egypt. On the other hand, the conflict in the conservative camp, between the supreme leader, Ali Khamenei and the president Mahmoud Ahmadinejad attracted growing attention of the Iranian public. The article aims to analyze the causes of the conflict in the conservative camp, to characterize the rival political groups and will attempt to answer the question about possible consequences of this conflict, not only for the reformists, but for the Iranian political system, as a whole. As the results of elections to the 9th Majles show, Ali Khamenei continues to have the greatest impact on the balance of power in the Islamic Republic, but taking into account the growing influence of the Revolutionary Guard Corps, they may become much greater threat for Supreme Leader than the reformists.
