Martin Bashir

A television journalist hungry for the story of a lifetime, Bashir sets his sights on Princess Diana, isolated and mistrustful after years of press intrusion. He is patient, attentive, and persuasive, presenting himself as an ally who understands her better than anyone at the Palace ever has.

Puwanarajah plays him with quiet, unsettling sincerity rather than obvious slyness, which is the point: you watch him listen, adapt, and mirror Diana's wounds back to her, and the show lets you register how effective that gentleness is as a tool before you're asked to question it.
