Trump to pull out of Iran nuclear deal, US media reports suggest

Trump, who has previously described the deal as an “embarrassment” to the US, has repeatedly said the agreement is not beneficial to the country.

If Trump were to decertify the agreement, the decision would be left to Congress as to whether economic sanctions would be returned to Iran.

According to CNN, Trump will reveal the decision this week after he launched another attack on the country’s behaviour on Thursday.

"The Iranian regime supports terrorism and exports violence, bloodshed, and chaos across the Middle East," Trump said. "That is why we must put an end to Iran's continued aggression and nuclear ambitions. They have not lived up to the spirit of their agreement."

According to the administration, Iran has complied with the 2015 accord which saw it scaling back its nuclear programme in exchange for the lifting of economic sanctions.

UK Prime Minister Theresa May and her French counterpart Emmanuel Macron have both affirmed their support for the agreement, which must be certified every 90 days by all sides involved.
