YMB...you commented that our first-past-the-post system was "skewed" and I gave my response. It wasn't meant as a lecture, which I am sure you don't need, so I apologise !....just a point of information for others here today.
UKIP suffers from the same disadvantage that other minor parties are subject to in Britain, which is why some kind of PR is used in the Scottish and Welsh elections, and for the EC elections. Its very difficult, if not impossible for a new party to break through under our system.
For instance, in 2010 the LibDems achieved 23% of the popular vote but instead of getting 149 seats, (23 %) only got 57. The Greens, contrastingly got 1 seat on 0.9% of the popular vote, but UKIP had no seats, despite getting 3.1% !
So if UKIP is wanting to achieve a real breakthrough in Westminster, its difficult to see how they can do it with our present system. Having a tiny amount of seats after May 2015 will just not be enough to "break the mold"
