If London was a clock face then Uxbridge would be where the number 10 is on the edge of the clock. It is on the North west Edge of London next to the M25 orbital motorway (freeway); it circles London. It also sits next to the M40 motorway that goes to Oxford and Birmingham. The intersection between the M25 and M40 is very close to Uxbridge.
I'm very familiar with Uxbridge, it is the part of London that is nearest to my town. I go to Uxbridge often and drive through it to visit my parents. The train station is shared by the picadilly line and the metropolitan one and is the last station for both lines. There is also two shopping malls there next to the trian station. I know some people that live there, they told me they dislike both the main parties, their votes could swing in any direction depending on who they hate the most. The new MP for Uxbridge will be someone they dislike but hate less than the other guys, a compromise.
