Prompt
Generate a realistic image of a middle-aged British man with a dignified expression, wearing formal attire, possibly a suit and tie, with a subtle background hinting at his diplomatic or political career; he should be sitting in a chair with a gentle smile, conveying a sense of authority and compassion, with a few subtle hints at his international background, such as a UN or UK flag pin on his lapel; the style should be professional and respectful, suitable for a prominent public figure like Sir Stephen O'Brien.
