1845 GMT: We're going to catch our breath tonight after the excitement of today. We'll be back later for a wrap-up; in the meantime, keep sending in information and your analyses.
1820 GMT: Larijani's Opening? We'll need to get more on this statement by Ali Larijani, during Friday Prayers in Saveh, southwest of Tehran, but there is a hint in Mehr News that the Speaker of Parliament has extended a hand to different factions when it paraphrases, "Every effort should be made to foster unity in society, and everyone should refrain from divisive actions meant to drive individuals off the political stage."
The Persian-language report, significantly, devotes most of its attention not to the "unity" statement but to Larijani's critique of the Government's economic proposals.

The Latest from Iran (21 January): Speaking in Codes
1735 GMT: Press TV Censors Ahmad Khatami? Surely not, but the website curiously omits any mention of Khatami's warning to Iranian protesters and the call for all to choose the side of the Supreme Leader (see 1250 and 1645 GMT). Instead, the entire report is "Cleric Says Iran Nuclear Case Important 'Test'".
1730 GMT: Journalist Leili Farhadpour has been arrested.
1645 GMT: More on That Friday Prayer (see 1250 GMT). Persian2English translates passages of Ahmad Khatami's statement, which is his usual warning to deviant demonstrators:
To our brothers who call themselves protesters, we ask, how much longer are you going to continue with your protests? Are you still going to use your destructive statements which neglect the law? Are you going to water the roots of those who try to turn any cooperative situation into a conflict? They say it was not them who created the chaos; the question is who initiated this atmosphere? How long are you going to continue your protests and annoy the people?
This passage, however, does give pause for consideration: "The group who considers themselves critics should announce where they stand. Either they are on this side [with the Supreme Leader and velayat-e-faqih] or they are on the other side. There is no third way."
That seems to echo Ayatollah Khamenei's statement earlier this week on "make your decision", but to whom was Khatami pointing the statement? Those deviant demonstrators, or the "critics within" the establishment?
1530 GMT: The German magazine Der Spiegel reports that Abed Tavancheh has been sentenced to one year in an Iranian prison for giving an interview about student protests.
1525 GMT: Hassan Rohani, an ally of Hashemi Rafsanjani, has continued to clash with President Ahmadinejad over the "failed" 4th Development Plan. After the Government ridiculed his data, Rohani has responded in detail in Peyke Iran.
1515 GMT: Earlier today (0845 GMT), we noted the manifesto of 31 Iranian expatriate intellectuals and artists: "The way out of this darkness, and of poverty and oppression caused by it, is that people make clear their relationship with tyranny through free elections, monitored by competent international institutions." This will bring "a system separating government from religion institutions, on behalf of the Universal Declaration of Human Rights, separating legislative and executive powers, and [ensuring] judicial independence".
The statement has now been picked up by BBC Persian and by Radio Farda.
1309 GMT: The Purge at Allameh Tabatabei University. We've had reports this week of academic staff being terminated or relieved of duties. Putting them together:
Political philosopher Seyed Morteza Mardiha and women’s rights activist Saba Vasefi have been banned from teaching. According to Tabnak, eight faculty in the Economics Department have been expelled, and all but one stripped of the right to teach. The salaries of two faculty members of the Department of Agriculture have been cut.
The Development Program at Allameh Tabatabei has been completely terminated.
1250 GMT: Your Tehran Friday Prayers Summary. It's Ayatollah Ahmad Khatami setting out all that's significant in religion and politics today. Behold:
When you hold an election, that's the people's opportunity to put forth their views. Then someone wins and you stop for four years. Ahmadinejad won. So, protesters, be quiet.
And the US military is occupying Haiti, which proves they are very bad.
1240 GMT: Where's Mahmoud? President Ahmadinejad has opened a factory at Khorasan Steel and dealt with the current political crisis by calling on all Iranians to have a spiritual focus and obey Allah.
1235 GMT: Human Rights Activists News Agency reports that the files of 18 more Ashura protesters have been sent to the Revolutionary Court.
1015 GMT: We have posted comments from an EA correspondent on our featured analysis, "The Plot Against President Ahmadinejad".
0845 GMT: The Opposition Manifesto. More than 30 expatriate Iranian intellectuals and artists have issued a statement in support of Mir Hossein Mousavi.
0835 GMT: Slamming the Opposition. Last night's debate on Iranian state media was a non-debate, as MPs Ruhollah Hosseinian and Alaeddin Boroujerdi were generally in agreement. An EA correspondent describes it as a “Love-Making discussion in which both side were praising and appreciating each other".
There was some drama, however. In addition to his claim of "a plot within" to topple the Government, Hosseinian talked of the "Axis of Revolt" of Mir Hossein Mousavi and Mehdi Karroubi. He offered this advice: the Supreme Leader was too patient with the opposition --- "if we had the authority; we would have sorted it out straightaway".
0820 GMT: An Iranian activist has posted a list, with English translation, of the arrest and current state (if known) of 229 people arrested on 16 Azar (7 December) or in the Tasua-Ashura demonstrations (26-27 December).
0655 GMT: We are putting the last touches to what we believe is a significant story: a high-level plan to move against President Ahmadinejad and possibly remove him from office. As soon as that is completed, we will update on latest news. (We have now posted the story.)
