Create a highly realistic, photographic-style image of Rishi Sunak reimagined as Bungle from the classic TV show 'Rainbow'. Rishi Sunak should have the appearance of a large, friendly bear with a brown fur suit, but with his facial features clearly recognizable. He should be wearing a tailored business suit that seamlessly blends into the bear costume, maintaining a professional yet whimsical look. The background should be a simple, neutral backdrop to focus attention on the character. The lighting should be natural, as if taken in a professional photo studio, highlighting the textures of the fur and the fabric of the suit. The overall mood should be playful yet realistic.
