TEHRAN (Press Shia) – Iranian Parliament Speaker Ali Larijani slammed US President Donald Trump’s recent comments of about the 2015 nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA), and said the Islamic Republic would never accept a change in the deal.

Speaking at an open session of the parliament on Sunday, Larijani referred to Trump’s calls for “fixing” the JCPOA and said, “Iran’s parliament will not accept a change in the structure of the nuclear deal.”

“If they (the US officials) are entertaining such thoughts, they won’t need to wait for a few more months to know (that Iran’s position is not going to change),” he said, adding that they will regret it sooner or later.

Larijani also pointed to recent sanctions imposed by Washington against some Iranian companies and individuals and described them as illegal.

On Friday Trump again waived sanctions against Iran that were lifted as part of the landmark 2015 nuclear deal, but threatened he would terminate the agreement if “significant flaws” in it are not fixed.

“Today, I am waiving the application of certain nuclear sanctions, but only in order to secure our European allies’ agreement to fix the terrible flaws of the Iran nuclear deal,” he said in a statement.

“This is a last chance. In the absence of such an agreement, the United States will not again waive sanctions in order to stay in the Iran nuclear deal. And if at any time I judge that such an agreement is not within reach, I will withdraw from the deal immediately. No one should doubt my word.”

In October, Trump said he would not certify Iran’s compliance with the nuclear agreement that was negotiated under the previous administration.

He said he wants Congress to fix “the deal’s many flaws” such as existing sunset provisions.
