Mostafa Tajzadeh is a leading Iranian reformist politician and a member of the Islamic Participation Front. He has been in prison since the June 2009 presidential election. He served as a deputy in the interior ministry under the Khatami administration.
Here you can see a video of him making a speech before the election. I’ve translated his speech below.
[clip 1] Those who are my age know this, in the days of the Shah [prior to the 1979 revolution], the people of Iran had every kind of freedom, except for political freedom. That is, when one of the slogans of the revolution became esteghlal, azadi, jomhooriyeh eslami [independence, freedom, the Islamic Republic of Iran] by “freedom” they only meant political freedom. Which other kind of freedom was it that we didn’t have? [Religious wise], you could freely practice your religion. If you were the type who wanted to go to the mosque, you could, if you wanted to go to a bar, you also could. The path was open. The freedom we did not have was political freedom. We did not have a free press, we did not have free political parties, we did not have free elections, we did not have free unions … This is where the problem was. [In the days of the revolution], this is the tyranny which the people of Iran stood against. Thus, political freedom was one of the main demands of this nation. Just like the days of the Constitutional Revolution .
With what rationality did the Imam [Khomeini] put aside the constitution [the one during the Shah]? His most important reason, the brightest, most historic [reason] he put forth, was when he said: “our fathers, our mothers, in another time, thought that this constitution [the one under the shah] was the best. Today, their children are mature and wise, they recognize that they want a new constitution.” He thus acknowledged the right of every generation to govern its nation on its own.
[clip 2] It is imperative that the election be free, and if for any reason, anyone undermines this freedom, they are acting against the law. They tell us: “don’t worry” [about fraud in the election]. Well, we are worried. I personally am very distraught over what Mr. Mahsouli [Ahmadinejad's interior minister in the ninth cabinet] is doing over at the interior ministry. They are shuffling around and changing everybody these days, even the secretaries. I don’t know what they are doing in there that has become so secretive and confidential.
