With UKIP not "selecting" a disabled candidate, it has been easy for people to label them as picking on a poor disabled person. However, looking at UKIP home, it appears there is more to the story.
Perhaps I am misunderstanding this, but to my mind it appears the disabled chap in question made threats to go to the press "if" UKIP stood a candidate against his daughter, who appears to be a councillor for another party. Perhaps I have got the wrong end of the stick and the guy in question has not made any "threats" at all, and if so, I apologise.
I would recommend everyone read the link above and see what you make of it. It certainly seems to be a more complicated story than the one the press have been reporting.
