Andre Walker, a right-wing columnist, slated the SNP party for “not having a clue” when it comes to economics.
The outburst came as Nicola Sturgeon and her party accused Theresa May of pursing a “little Britain Brexit” which could lead to tens of thousands of jobs lost in the country.
Angus Robertson MP blasted the Government of pursing a “hard Tory Brexit plan” during Prime Ministers Questions on Wednesday.
Andre Walker blasted the SNP for "not having a clue" over economics
They simply do not have a clue on economics
He referenced economic experts who said “real wages” in Scotland would fall by £2,000 per year and that 80,000 people may lose their jobs if Britain quit the EU’s free trade bloc.
But, Mr Walker, a writer for the New York Observer, criticised the Scottish party over their track record of “not having a clue”.
“The SNP said that two million jobs would be lost if we didn’t join the Euro. The SNP are wrong. They simply do not have a clue on economics,” he blasted on STV.

When told the research had come from a Fraser of Allander Institute, Mr Walker snapped back: “I could give you 50 reports that told us not joining the euro would cost jobs – they turned out to be completely wrong.”
Speaking to former justice secretary Michael Gove for an interview with The Times, the president-elect said: “We're gonna work very hard to get it done quickly and done properly. Good for both sides.”

Mr Walker hailed the Republican’s comments as he referred to the president-elect as “the greatest living Scotsman” ahead of Friday’s inauguration.
“He said that the free-trade deal with the United States and the EU is dead and that the deal with the United Kingdom is very much on – so I would take the United States trade deal over the EU trade deal any day,” the columnist continued.
“The stock market is booming, we’re on for a trade deal with the United States of America. Actually, the stupidity here, just because you want a few MEPs on the gravy train in Brussels you’re willing to risk the Scottish economy.”

In December, the Holyrood administration published its post-Brexit plan, begging for a “flexible” approach which would take into account the needs of different parts of the UK.
During her landmark speech on Tuesday, the prime minister said although devolved administrations would help formulate an overall deal to accompany the UK’s departure from the EU – only the Houses of Parliament would have a vote.
There was also no talk of a special deal for Scotland as Mrs May made clear the UK as a whole would be seeking negotiations.
