UK: Minor Party vs. Major Party Political Strategy

From Michael Savage at the Independent:

While teams of strategists for the three main political parties have been scratching their heads and poring over electoral maps to decide how best to maximise their return of parliamentary seats, the three smaller parties have a much more straightforward task in deciding where to deploy their limited resources.

The Green Party, the UK Independence Party (Ukip) and the British National Party (BNP) each has one obvious constituency in which to focus their efforts as they attempt to secure a seat in the Commons for the first time.
