Speaking to the camera, Line of Duty star Vicky says: "Everyone that sees him. I mean, obviously, he's got his medals on today, and he looks incredible.

In a sweet moment, Vicky turns to the 97-year-old and declares: "I'm so proud of you, Grandad. I'm so grateful."
He responds by joking: "Now, don't you get me embarrassed as well."
