As far as I'm aware, PPE is a new degree being offered at Sussex for 2013. So you're not going to find any success stories from PPE graduates from Sussex since there are none! I studied Politics and European Studies (the latter was a bit of everything, IR, Economics, History etc) and I think very highly of the Politics department of Sussex. They're putting good money into it too - with a brand new academic building for 2013 for Economics/Politics/Business. Pretty jealous considering most of my classes were in portacabins while it was being built! Sorry I couldn't help any more.
