"During the last visit by (IAEA director general) Mohammad ElBaradei (in early April), it was agreed that Iran would present a series of declarations to the IAEA, focussing in particular on the contamination of nuclear equipment and the P2 centrifuges," the paper said, citing a "well informed source".

"This well informed source added that by handing over these declarations today, Iran believed it would have cleared up all misunderstandings with Mr ElBaradei," the paper added.

At its last board of governors' meeting in March, the IAEA chastised Iran for not coming clean about its manufacture of P2 centrifuges used in uranium ennrichment.

The watchdog also demanded more evidence from Iran to back up its insistence that traces of highly enriched uranium found by IAEA inspectors on nuclear equipment was the result of contamination prior to its importation.

Under the additional protocol of the nuclear Non-Proliferation Treaty, which Iran signed amid great fanfare last December, the government is required to provide a full report on it nuclear programme by mid-May.

It was unclear whether the "declarations" referred to by the Iran newspaper were that report or a separate document addressing the specific issues raised by the IAEA in March.

The watchdog's board of governors meets again in June amid mounting demands from Iran's archfoe the United States for tougher action against what it charges is a covert weapons programme.
