TEHRAN — Five days after national elections in Iran, the Interior Ministry has yet to release official detailed results, and some analysts are beginning to doubt that it ever will.

While the government and its supporters clearly won a sweeping victory in the capital, the picture in the rest of the country is much more diffuse and may remain that way for some time, if not permanently.

The Interior Ministry, which is overseeing the voting for the 290-seat Parliament and the clerical Assembly of Experts, announced on Tuesday the names of 222 parliamentary candidates who won nationwide. It also announced that there would be a second round of voting for 68 seats in several constituencies in April.

But there has been no official comment on the affiliation of the winning candidates, and there may never be, making it difficult to determine how many seats the various factions have won.
