Iran’s Foreign Minister Mohammad Javad Zarif and the European Union’s Foreign Policy Chief Federica Mogherini are among top contenders for this year’s Nobel Peace Prize which will be announced later this week.

Zarif and Mogherini led the Iran nuclear deal negotiations that resulted in the signing of an agreement between Tehran and the P5+1 group of states – the US, Russia, France, the UK plus Germany.

Henrik Urdal, the head of the Peace Research Institute of Oslo (PRIO), which makes a shortlist each year with mixed results, has described the two as strong contenders this year.

According to Urdal, the two are the best candidates because of their significant role in the negotiation process that led to the deal, which has been praised worldwide as a victory for international teamwork and diplomacy.

This is while U.S. President Donald Trump has been constantly threatening to scrap the deal since he assumed office.

The agreement, officially known as the Joint Comprehensive Plan of Action (JCPOA), removed the nuclear-related sanctions against Tehran in return for some restrictions on Iranian nuclear activities.

Israel and the Trump administration are the only critics of the deal.

During his UN speech last month, Trump said the JCPOA was an “embarrassment” for the U.S. and threatened to withdraw from the accord.
