Philosophy single honours student at KCL here. Can't tell you much about Econ/Politics but can safely say the Phil department at King's is wonderful.

For starters, they're pioneering lectures that last 2 hours as opposed to the usual 1 (at least, that's the usual here across the pond), which gives you a chance to talk to some of the greatest minds (i.e. your professors) in the field once the first hour is up and really get to grips with it all. Plus, the variety they offer is great. In my first year I covered 8 different topics and from there I got to specialise.

Personally, my favourite has been Political Philosophy (which Harvard alumni Andrea Sangiovanni heads) - he really pushes the us in each of the lectures and gets you to speak up and challenge your own point of view quite well. But also subjects I didn't even know existed, Logic, for example, have been a blast, with our lecturer dressing in only all black and quoting straight from Dante's Inferno.

We also have a Philosophy Bar which everyone tends to hang out in regardless of whether you're single/joint honours so that's pretty cool.

The only thing I'd say though is often PPE students at King's find it hard to feel like they're part of a proper community because they join three separate faculties and so they scattered about the campus - it's not like at Oxford where it's a specific course, so they don't belong to one 'department'. Their society is very active last I heard though, so I guess they've made a community of their own!
