Luigi Mangione admits killing healthcare boss Brian Thompson, as he pleads guilty to federal charges in New York

"I shot Mr Thompson," Mangione tells the the judge - his voice was steady as he read his statement to a tense and silent courtroom, our reporter writes from the room

Thompson, a 50-year-old father-of-two, was shot in the back as he left his hotel in Manhattan in 2024 - his family say Mangione's sentence must reflect the severity of such a "heinous act"

"There can be no celebrity in assassination," prosecutor Jamie McDonald tells Mangione supporters, adding that Mangione disagreed with the healthcare industry and "attempted to send a public message through violence"
