Update: The Scottish National Party has called on Better Together to disown Ukip's Scotland MEP David Coburn's "ludicrous and insulting remarks". In response, Coburn told HuffPost UK: "It seems I've angered the hive mind!"
A spokesperson for the pro-union campaign said: "David Coburn and UKIP are not part of the Better Together campaign."
Scotland's first and only Ukip MEP David Coburn has branded Alex Salmond a "prototype dictator" and "master of the Borg".
The ex-chancellor made his remark after Salmond blamed Ukip getting enough votes to see Coburn elected on the BBC "beaming" Ukip directly into Scottish voters' homes.
Speaking to the Huffington Post UK, Coburn, tore into the Scottish National Party for "having one mind", like the Star Trek villains.
"Alistair Darling has hit the nail on the head," he said. "The SNP is like a cult, it's terrifying. Salmond is like Kim Jong-Un, he is master of the Borg, the Borg-in-chief!
"They all follow behind him. Nobody says anything wrong, it's always the same nonsense, there's no humanity to them. It reminds you of the Moonies, or some of the crazy American sects."
Coburn went on to compare the Scottish National Party to Daleks, the infamous villains in Doctor Who, adding: "If you listen to [SNP deputy leader] Nicola Sturgeon, she's Chief Dalek".
He added: "They take all their candidates and all the people that speak for them, put them in the cellar, thrash them with rubber hoses in stress positions until they trot out the same story. Nobody says anything wrong, there's no humanity them."
Coburn dismissed Salmond's attack on the BBC for helping Ukip get votes as "utter twaddle". "Salmond made it his business, aided by the authorities, that Ukip in Scotland was to be treated not as a major party and I had to fight my way to get market share."
"They tried to squash us but we still came through."

The Ukip MEP, who has described the Scottish First Minister as the "Robert Mugabe of Scotland", said Salmond was a "prototype dictator" who had "bullied Scottish business and anytime they disagreed with his economics, he just trashed them in public and got the cybernats onto them."
Coburn said that he believed Salmond would fail to convince Scots to vote for independence in September's referendum, musing: "The question is how badly he's going to lose and we want it to be as badly as possible."
However, he warned that the Better Together pro-union campaign was not putting its message out "hard enough".
Coburn said: "They're not ramming it home hard enough, they should be much more truthful about the state of play after independence. It's a matter of telling people what the problem will be afterwards."
The Ukip MEP said that his party "doesn't do media training", quipping: "Our media training is we go to the pub."
Coburn did not deny that some Ukip candidates have said controversial comments, adding: "We can always rely on our lunatic fringe to say something silly. Nigel says it's like herding cats!"
