In another answer, Evans claimed IT problems prevented UKIP from getting a membership boost following the election like Labour and the Lib Dems.

"Apparently, so I'm told, someone who I gather is no longer working for us decided to launch a new website two days before the GE which didn't work properly," wrote Evans. "Goodness knows how many potential new members we lost. An awful, wasted opportunity."

She also touched on "tea party types" – in an apparent attack on Nigel Farage's outgoing aides Raheem Kassan and Matthew Richardson – who she believes have attempted to outdo the Tories by taking UKIP further and further to the right.

"Sadly I think there are a few 'tea party' types who would drag UKIP back to being a right-wing 'more Tory than the Tories' party, yes," she said. "Personally, and especially given how our messages are resonating with former Labour voters, I sincerely hope that won't happen."

However, she said climate change sceptics within the party had prevented her from including more environmental policies in the manifesto, and from hiring an environment spokesperson.

"Personally I don't think caring for the environment and belief in man-made climate change, which many in UKIP are skeptical about are inextricably linked," she said.

"I would have liked to put more environmental and stuff in the manifesto but we don't have an environment spokesman and the manifesto was mostly tied into the policy areas we already have spokesmen and women for."
