More Farage, more immigration

This title is clearly a provocation. How can a politician who has garnered support from about 15% of the British electorate on a policy of restricting immigration, actually generate the opposite result? I’m careful to say ‘restrict’ in line with the UKIP website, which recognises ‘the benefits of limited, controlled immigration’. Perhaps it would not be too far off the mark to say that many of UKIP’s supporters are more attracted to the party’s promise to ‘leave the EU, and take back control of our borders.’ A study of UKIP voters found that ‘on immigration, hostile views were widespread, but UKIP voters were consistently the most intolerant group after the British National Party’. Why are these sympathisers of Nigel Farage likely to be disappointed?
