INTRODUCING a super-majority in a second independence referendum would leave democracy in “tatters”, Michael Russell has warned.

The Constitutional Relations Secretary responded at FMQs to suggestions a two-thirds majority may be required for indyref2.

Unionist campaigners recently tabled a petition at Holyrood calling for such a threshold, but the Scottish Tories said they would not support that position.

After the issue was raised by SNP MSP Sandra White, Russell hit out at Unionist politicians and journalists for promoting a two-thirds minimum. Citing the 1979 devolution referendum, which did not pass because too few voters backed it, he warned of a potential “cheat”.

The SNP minister said: “A fundamental tenet of democracy is that one person’s vote is worth as much as anyone else’s. The suggestion of a super-majority would leave that principle in tatters.”

White said the Venice Commission on referendums, the advisory body on the Council of Europe, had warned a super-majority could encourage people not to vote.

Russell added: “I know that Tory-supporting journalists and indeed Tory MSPs are actively promoting a variety of issues in a referendum, including a variety of turnout requirements and quorums.

“The Venice Commission is entirely clear. A turnout quorum, threshold or minimum percentage is wrong because it assimilates voters who abstain with those who vote No, and an approval quorum, which is approval by a minimum percentage of registered voters risks involving a difficult political situation.

“If, for example, as of course happened in 1979, there is a simple majority, but an artificial, one might call cheat, applied by other people.”

Scottish Tory interim leader Jackson Carlaw said support for a super-majority was not party policy.

Russell said he was "delighted" to hear Carlaw outline that position.

He also criticised Scottish Tory MSP Murdo Fraser over a tweet sent on the fifth anniversary of the referendum last week, in which he wrote: "Leave/Remain and a two-thirds majority required. Bring it on", including a "wink face" emoji.

Fraser responded: "What a sensitive soul the Cabinet Secretary is. He clearly can't take a light-hearted comment on Twitter with a wink emoji as anything other than that.

"But isn't it true that this Government is running scared of having a fair referendum, running scared of having the Electoral Commission decide on the terms of the question?

"We don't want another independence referendum, the people of Scotland don't want another independence referendum but we can't have the SNP gerrymander one if there is to be one."

Russell said: "What the people of Scotland want is to move forward from the extraordinary Tory-created chaos of Brexit and the opportunity to do so exists if the people of Scotland choose their own constitutional future.

"Anyone who stands in the way of that isn't a democrat."

Scottish Greens co-leader Patrick Harvie said: "If a supermajority procedure had been in place for the last five years, there would have been neither a mandate for independence, nor for staying in the UK, neither for leaving or remaining in the European Union.
