Joint degrees: where can i find them?

Hi, can you tell me what universities in London offer the possibility to apply to joint degrees? I'm specifically interested in a course that teaches you both Business and Graphic Design.
For example, I know that Kingston University offers you something like that, with its "History of Art, Design and Film with Business" joint degree, but I think that, on the graphic side, it's only a theorical course, where they teach you the history of design, rather than "how to make design on your own". I'm more interested in the pratical side: i would like to learn how to use graphic programmes on computer and that kind of stuff. And i would like to learn some business too.
Where can i find a joint, or dual (?), degree like that? Graphic design AND Business, for and undergraduate.
Thank you
