“I had difficulty not wanting Boris Johnson to die. I wanted him to die,” Margolyes, who is most known to US audiences for her role as Professor Sprout in the “Harry Potter” film series, told show hosts.

“Then I thought that will reflect badly on me and I don’t want to be the sort of person that wants people to die,” she continued. “So then I wanted him to get better, which he did do, he did get better. But he didn’t get better as a human being. And I really would prefer that.”

Margolyes, 78, a longtime Labour party activist, was responding to a question about her views of how the British government was handling the coronavirus crisis — which she criticized as “appalling.”

The actress has a long history in British and American entertainment with roles in the comedy series “Blackadder” and Martin Scorsese’s “The Age of Innocence,” which netted her a BAFTA award for Best Supporting Actress in 1993.

Her outburst caused some criticism online, including from morning show host and ex-CNN anchor Piers Morgan.

“Disgusting,” he castigated in a tweet. “This is where toxic tribalism has got us.. actively wanting people of a different political persuasion to die. Shame on you Ms Margoyles.”
