Washington (CNN) Kim Darroch, the former United Kingdom ambassador to the United States, said the Trump administration was "set upon an act of diplomatic vandalism" in its decision to abandon the Iran nuclear deal, the Mail On Sunday reported Saturday, citing leaked cables.

According to the Mail On Sunday, the former ambassador said Trump seemed to be discarding the Iran nuclear deal for "personality reasons," as the deal had been agreed to by former President Barack Obama. The paper also reported that Darroch hinted at discord brewing between Trump's closest aides and said the White House had failed to produce a "day-after" plan on how to handle the aftermath of withdrawing from the deal.

CNN has not seen the leaked cables and cannot confirm their contents.

The White House told CNN it has no comment on the story.
