Nigel Farage has made a pitch for SNP voters saying Scottish independence would only be possible if the UK first leaves the European Union.

The leader of the Brexit Party said that talk of Scottish independence while still in the EU is the "most dishonest political discourse I've ever seen anywhere in the world".

Speaking at a rally in Edinburgh, the former Ukip leader said: "Our politics is full of deception because here in Scotland we have the extraordinary situation where Nicola Sturgeon talks about independence.

"She says that separating from the United Kingdom but staying part of the European Union means that Scotland will be independent.

"It is, I think, the most dishonest political discourse I've ever seen anywhere in the world.

"You cannot be independent if you're governed from the European Court of Justice. You cannot be independent if you're in the EU's customs union and single market. You cannot be independent if you're governed by Monsieur Barnier and Mr Juncker."

He suggested that up to 30 per cent of SNP voters do not want to be part of the EU, and added: "Even though I'm very unionist, I would say to those voters: unless we get Brexit, you cannot really have an intelligent debate about Scotland's future.

"Actually, what you ought to do, folks, is at this election lend your votes to the Brexit Party. Let's get out of the European Union and then have an honest debate about the future of Scotland."

Responding to comments by Scottish candidate Louis Stedman-Bryce that the party would not stand in the way of a second independence referendum, Mr Farage told reporters: "He said he wouldn't stand in the way of it, but he also said that – given that it was said at the time that it was a once-in-a-generation vote – it shouldn't happen for a very long time.

"The same thing applies to the Brexit referendum. We were told this was a once-in-a-generation decision."

Asked about receiving £450,000 of funding from the businessman Aaron Banks in the year after the 2016 vote – a claim he earlier denied but one that Mr Banks reportedly confirmed – Mr Farage claimed the issue was a private matter.

He said: "Whatever happened after the referendum, I was leaving politics, it was happening mostly in America, had nothing to do with politics, nothing to do with the Brexit Party, it was purely on a personal basis.

"I was looking for a new career and a new life, it's got nothing to do with anything. It's a purely private matter."

Pressed on whether he declared it, he said: "Of course not, of course not. It's a purely private matter, non-political in absolutely every way.
