LONDON — Boris Johnson called Tuesday for the current nuclear deal to prevent Iran acquiring nuclear weapons to be replaced with a "Trump deal."

In his first major television interview since becoming prime minister, Johnson warned the U.S. president that if he were to scrap the current nuclear deal with Iran he must find a "replacement."

Speaking to the BBC, Johnson acknowledged that from the U.S. perspective, the current deal, known as the Joint Comprehensive Plan of Action (JCPOA), had "many, many faults" and said it would be a "great way forward" to replace it.

"President Trump is a great dealmaker, by his own account and many others. Let's work together to replace the JCPOA and get the Trump deal instead. That is our opportunity," Johnson added.

The prime minister said he is glad the Iranians had accepted responsibility for shooting down a Ukrainian passenger jet killing 176 people.

"I think they were clearly guilty of an appalling error. I don't think that we are currently envisaging any further escalation of the tensions."

He said there had been no reason for the U.K. to be notified in advance of the U.S. decision to kill Iranian General Qassem Soleimani. "It was not our operation."
