So Manchester and Leeds is not a particular majority Tory or Labor reliable voting block? Interesting that its a moderate area. That certainly is different from much of America.I think its safe to say that certain states in America are known to be either blue or red states.
You don't really get that same distinction between different parties in the UK... probably because actually there isn't all that much difference between them anymore

.
I couldn't really tell you any particular area of the UK which is specifically Tory or Labour... there are counties where one party tends to win over the other in each election (i.e. the Lib Dems have been winning in my home county for 15 years now), but it doesn't seem to really mean all that much. Like with religion, people in the UK don't really talk about their political views that much in everyday conversation... it's a bit of an awkward subject. I don't know which parties any of my friends or colleagues vote for and I won't be asking them... that's their business, not mine.
All three main parties are actually considered right-wing now: Labour used to be left wing but are now right-wing (they are just to the left of Tories) and Lib Dem also used to be more left. In general, Labour tries to appeal to the more working class and Conservatives try to represent the middle and upper classes. See this diagram for an idea of where each party lies (there is also a diagram at the bottom showing how the parties have shifted over the years):

There is quite a lot of variation within different cities and counties, so it's more like certain parts of an area have a lot of Tories vs. Labour supporters, rather than a whole county or city being known as being one or the other.
Even within individual families, there can be political party variations. My parents vote conservative (not because they are particularly conservative themselves, but because they don't want Labour in power

), while in the last election I voted Lib Dem. I have no idea what parties my brothers support, or if they even voted in the last election.
