Iran
After the Supreme Leader, the Constitution defines the President of Iran as the highest state authority. The President is elected by universal suffrage for a term of four years, however, the president is still required to gain the Leader's official approval before being sworn in before the Parliament (Majlis). The Leader also has the power to dismiss the elected president anytime. The President can only be re-elected for one term.
The President is responsible for the implementation of the constitution, and for the exercise of executive powers in implementing the decrees and general policies as outlined by the Supreme Leader, except for matters directly related to the Supreme Leader, who has the final say in all matters. Unlike the executive in other countries, the President of Iran does not have full control over anything, as these are ultimately under the control of the Supreme Leader. Chapter IX of the Constitution of the Islamic Republic of Iran sets forth the qualifications for presidential candidates. The procedures for presidential election and all other elections in Iran are outlined by the Supreme Leader. The President functions as the executive of affairs such as signing treaties and other international agreements, and administering national planning, budget, and state employment affairs, all as approved by the Supreme Leader.

On 2 February 2013, speaking at the Munich Security Conference, U.S. Vice President Joseph Biden said that the Obama Administration "would be prepared to meet bilaterally with the Iranian leadership. We would not make it a secret that we were doing that. We would let our partners know if that occasion presented itself. That offer stands, but it must be real and tangible, and there has to be an agenda that they’re prepared to speak to. We are not just prepared to do it for the exercise." A few days later Iranian supreme leader Ayatollah Ali Khamenei rejected the offer and added ambiguously: "The U.S. policies in the Middle East have failed and the Americans are in need of a winning hand. That is bringing Iran to the negotiating table." On 4 February the Italian news-wire "Agenzia Nova", citing "sources in Teheran," reported that "from the beginning of the year Ali Larijani, Speaker of the (Iranian) Parliament, secretly traveled twice to the United States" to launch direct negotiations with the Obama Administration. The Italian Agency explained that U.S. diplomacy was waiting for the Presidential election in Iran, that most probably will see a dramatic change in Iranian approach. It was reported on 17 June Iran’s newly elected president Hassan Rohani had expressed readiness for bilateral talks with Washington, with conditions.
