Quick one - are we proportional representation, or other?

[IMoveTheStars]

I don't understand it - my knowledge of this is 10 years old, and forgotton. Please can someone explain how voting works (element of urgency as DP is saying I'm wrong )

First past the post. Not PR

You vote for your local MP, they make up gov, majority party governs.

Its first past the post gets elected - even if they only win by a tiny amount

My (excellent) history teadher explained it all, but I'm 32 now and can't remember the interesting details. Thanks you all...
