That's very interesting about the official "major party status", thanks for sharing that. I was only considering General Elections, which are a fairer representation of a parties vote share (despite FPTP) as not all councils vote in local elections each year.
He's never been a MP, UKIP has never been considered a "major party" (how is this even defined?), there was no election in 2014, UKIP won 12.6% in 2015. He's clearly representing some people but your facts are way off.
