BORIS JOHNSON and Donald Trump were accused today of “shirking responsibility” by hiding behind a “sham proposed nuclear agreement” with Iran. 

International secretary of the Tudeh Party of Iran Navid Shomali said Iran would be unlikely to accept the new “one-sided deal” proposed by the two leaders.

Mr Johnson said today that the Iran nuclear deal should be replaced by a “Trump deal” after the US President walked away from the Joint Comprehensive Plan of Action (JCPOA) in 2018.

The PM said he recognised Mr Trump’s concerns that the JCPOA was “flawed,” partly because it was negotiated by former US president Barack Obama.

Mr Shomali, said: “We do not share Johnson’s description of Trump as ‘a great dealmaker.’

“In fact, all evidence points to the contrary — with Trump having wrought havoc on the Middle East through his undermining of internationally recognised agreements on the status of East Jerusalem, the Golan Heights, the occupied territories, as well as his unilateral torpedoing of the JCPOA.”

He said this “does not inspire any confidence in a deal being reached,” especially after Mr Trump threatened just over a week ago to bomb cultural sites in Iran  — knowing “full well” that this would constitute a war crime.

Mr Shomali added: “We believe that if the US has any real interest in reaching a deal and workable solution with Iran, it should refer back to the JCPOA — a deal painstakingly reached after more than three years of negotiations between the countries involved.

“We are totally against any one-sided deals that would serve only to humiliate Iran and which are propped up by the threat of yet more crippling sanctions on an already screaming country.”

In the Commons today, shadow foreign secretary Emily Thornberry accused Mr Trump of acting like a “toddler” for having rejected the JCPOA because it was negotiated by his predecessor.

Ms Thornberry asked whether it was the government’s official policy to replace the JCPOA with a “mythical Trump deal.”

Foreign Secretary Dominic Raab said that the PM supported it and said that French President Emmanuel Macron has also argued for a new deal.

Britain, France and Germany triggered a dispute-resolution mechanism (DRM) today, insisting that they were doing it in “good faith” because Iran was not “meeting its commitments” under the JCPOA.

Iran has suspended all limits on its production of enriched uranium, and has said it is responding to sanctions reinstated by the US.
