Yusef Kabira is Vesper Lynd’s boyfriend, mentioned in Casino Royale, and portrayed in Quantum of Solace by Simon Kassianides.
Early in the film, M mentions that a corpse with his identification documents is found washed up on the island of Ibiza, but a DNA test using locks of his hair from Vesper’s apartment proves it was another man’s body. His small but dark role is seen at the very end when Bond confronts him in Kazan saying they have ‘unfinished business’. To M’s surprise Bond does not kill him, but instead leaves Yusef to be taken into custody by MI6. Yusef is a bait used by Quantum to lure unsuspecting agents and officials such as Lynd and Corinne Veneau into Quantum’s schemes.
