Speaking on BBC Newsnight, Mr Wishart stated that the Scottish National Party’s sizeable gain in the election was a reflection of the Scottish population’s desire for another referendum. He said: “Obviously it’s massive for Westminster to give us a Section 30 order - but we’re getting there.”
“I think the result we had in Scotland last week where we secured 48 members of Parliament, reinforces the case that Scotland has that right to choose.”
Prime Minister Boris Johnson has been quick to stamp out any possible second referendum for Scotland.
He stood firm on his position following the election, saying that the Government must stay true to the result from five years ago, where Scotland opted to remain as part of the UK.
“He’s going to say ‘no’, we know that - he’s going to say ‘no’ for a few weeks or months, but already we’re beginning to see the cracks,” said Mr Wishart.
“Already significant members of the Labour Party in Scotland are opening themselves up to the prospect of an independence referendum.”
One online user commented: “This nonsense - no matter how often it's repeated, it is still nonsense.”
Another vented their frustration: “How is 45 percent of the GE vote, or 30.6 percent of the total Scottish electorate a mandate? A referendum is based upon the electorate not the number of seats.
“This is nothing more than cheap opportunism on the back of prejudice against the Sassenachs [English].”
This comes as Mr Johnson took a swipe at the SNP during a speech in Parliament.
The Prime Minister was listing new policies, dubbing them a “a blueprint for the future of Britain”.

He had not yet finished his speech when the SNP interrupted, demanding “Scotland have their say” because they “reject Parliament.”
Mr Johnson retorted: “This one nation Government will strengthen England, Scotland, Wales and Northern Ireland”.
In the election, the Tories lost seven of the 13 seats they held in Scotland.
SNP leader Nicola Sturgeon described it as a “crushing defeat”, while senior Conservatives in Scotland have said that the Prime Minster had already spoken to them about the huge task they face in keeping Scotland in the UK.
Mr Johnson has spoken to Ms Sturgeon during a phone call and he made clear his total opposition to a possible referendum, despite her labelling it a “democratic right”.
A Downing Street spokesman said: “The Prime Minister spoke to First Minister of Scotland Nicola Sturgeon and reiterated his unwavering commitment to strengthening the union.
“On Brexit, the Prime Minister said that he is now in a position to get this done in a way that allows the whole of the UK to move forward together, providing certainty for Scottish businesses and improving the lives of people right across Scotland.
“He added how the result of the 2014 referendum was decisive and should be respected.”
Ms Sturgeon tweeted in response: “And I made clear that @theSNP mandate to give people a choice must be respected - just as he expects his mandate to be respected.”
A spokeswoman for Ms Sturgeon said: “This was a constructive call in which the First Minister indicated she would be publishing a paper next week and the two leaders agreed to have a more detailed discussion in the near future over the issues raised by the election result.”
Ian Murray in Edinburgh South was left as the only Labour MP in Scotland following last week’s result.
