LONDON — A man who drove a van into worshipers near a London mosque, killing one man and injuring a dozen others, was sentenced on Friday to at least 43 years in prison for what a judge said was the result of “malevolent hatred.”

Judge Bobbie Cheema-Grubb said that mind of the driver, Darren Osborne, had been “poisoned” by far-right ideas before the June 2017 attack and that he had shown no signs of remorse.

“Your mind-set became one of malevolent hatred,” Judge Cheema-Grubb said. “This was a terrorist attack. You intended to kill.”

She sentenced Mr. Osborne, 48, to life with no chance of parole for 43 years, saying “the court has seen no evidence that the danger you present has lessened.”
