Why are People Voting UKIP?

Wesley Stephenson hangs out in the Essex district of Thurrock and tries to find out why so many of its voters deserted Labour and the Tories for UKIP. In the European and local council elections the UKIP vote jumped 163 percent in Thurrock. The council area comprises one of the most marginal Westminster seats in the country, so what will this mean for the general election and can what's happening in Thurrock tell us anything about the rise of UKIP elsewhere in the UK?
