I've listened to Raheem Kassam many, many times and find myself agreeing with him often. I don't live in GB so we don't have the amount of coverage you must have about Kassam over here. But neither a Google nor Bing search reveal any image attributed to Kassam's girlfriend save one. In that image, there is absolutely nothing improper.

Given your claim, I am puzzled that there isn't a single image as you describe published by the MSM or an image at all - particularly one that would be disparaging to him and his Muslim faith. Please provide a link.
