Jackie Bailey suggested that the SNP was unreliable as it urged British labor employers to reject any future alliances.
Scots Party No. 2 warned that an agreement between rivals would be an “uninterrupted catastrophe”.
And it referred to the 1979 Commons no-confidence vote in which Nuts helped topple James Callaghan’s minority government and paved the way for Margaret Thatcher to be “anti-labor.”
Speaking at a fringe event of the Labor Conference in Brighton, Ms. Bailey said: “Considering the so-called progressive alliance, no matter how attractive, it will be an unstoppable catastrophe.
“The SNP is always anti-labor. They overthrew the Labor government that began in Thatcher.
“It doesn’t play well in England either. The SNP bases much of its politics on grievances with the rest of the UK.
“His supporters – especially on social media – go a long way and this is a translation of a complaint against English.
“English voters don’t want to see a nationalist tail waving a UK Labor dog.”
In 2015, a Tory campaign poster had a picture of then-Labor boss Ed Miliband in Alex Salmond’s pocket, which Ms. Bailey claimed led to her election defeat.
And the Conservatives claim that Jeremy Corbyn and Nicola Sturgeon’s party are secretly negotiating an agreement before the 2019 general election.
Ms Bailey warned Sir Kerr Starmer that there was no way for Labor to regain power in Westminster that “does not pass through Scotland”.
And he insisted that the party should target SNP voters north of the border.
In another swipe at Nuts, Dumbarton MSP said he lacked backbench talent and claimed there was no “clear successor” to Ms. Sturgeon.
Ms Bailey added: “I think this shows the weakness in the SNP.
“While I think the next generation of labor talent is there and growing.”
SNPMSP Stuart McMillan retaliated, citing Labor’s position in the 2014 Indie Vote.
He said: “Jackie Bailey has a personal experience of destructive unity with his key role in better unity.
“The alliance with the Tories has led directly to the unforeseen catastrophe that is Bridget and we are now suffering the serious consequences.”
Tory MSP Donald Cameron added: “Many Labor MSPs openly support another harmful, divisive referendum.
“And the party is already working with the nationalists in six councils.
“Scottish labor cannot be relied upon merely to take into account the SNP-Green alliance.”
This came as Opinium voters Chris Curtis claimed that Labor had “gone through its worst point” in terms of voter turnout.
