President Trump on Wednesday defended surprising the grieving parents of a British crash victim with the American woman accused of killing their son — but blamed UK Prime Minister Boris Johnson for the plan.

The family of Harry Dunn, 19, said they were “shocked” when they were invited to the White House Tuesday afternoon — only to be told Anne Sacoolas was in the next room for their first meeting.

Trump on Wednesday insisted he was just trying to broker a meeting he was sure the family wanted — because Johnson had asked.

“I spoke with Boris. He asked me if I’d do that. I did it,” Trump told reporters Wednesday.

“I offered to bring the person in question in, and they weren’t ready for it. But I did offer.”

Sacoolas, the wife of a US diplomat, is accused of fatally hitting Harry in a wrong-way crash in the UK last month — before fleeing the UK by claiming diplomatic immunity.

The dead teen’s parents — Charlotte Charles, 44, and Tim Dunn, 50 — had previously insisted they would only meet Sacoolas if she returned to the UK to face justice.

“They wanted to meet with her,” Trump said. “Unfortunately, when we had everybody together, they decided not to meet.”

“Perhaps they had lawyers involved by that time, I don’t know exactly. I know the people were lovely,” he continued.

Calling the “beautiful” meeting “very sad,” Trump once again expressed sympathy with Sacoolas, who admits she was driving on the wrong side of the road when she hit Dunn’s motorcycle in Northamptonshire in late August.

“That happens in Europe,” Trump said. “You go to Europe and the roads are opposite.”

“And it’s very tough if you are from the United States, you do make that decision to make a right turn, when you are supposed to make a left turn. That happens to a lot of people, by the way. She says that’s what happened,” he continued.

The president ended by stressing that he had “expressed condolences on behalf of our country” to the Dunn family.

Sacoolas, the wife of US intelligence officer Jonathan Sacoolas, said through her lawyer that she had wanted to deal with the matter “privately.”

“Anne accepted the invitation to the White House with the hope that the family would meet and was disappointed,” a statement said, according to The Sun.
