It's a world away from the well-briefed and rehearsed political mainstream TV discussion.

In place of a comfortable studio, is a car.

And the interviewer is a London taxi driver.  Or so it seems.

The interviewee is SNP Glasgow East MP and co-founder of the Women for Independence group, Natalie McGarry.

The Herald:

And in a 45 minute chat she controversially rips into the monarchy and expresses outrage at the wine at £1354 a bottle at the recent Chinese state banquet.

The Artist Taxi Driver is otherwise known as Mark McGowan, a street artist and prominent public protester.

On You Tube he adopts the Chunky Mark persona where he films himself in his taxi between fares, often wearing dark sunglasses, and rants about the news and issues of the day.

This time the rants are with the 34-year-old MP who was elected in May, taking the seat from former Labour MP Margaret Curran as part of a historic election result that saw the SNP win 56 out of Scotland's 59 seats at Westminster.

The Herald:

It did not start well.

She had had problems before meeting her unconventional interviewee, most people would not associate with an MP, including, having  no electricity in her flat and running out of data on her mobile phone.

While the SNP has always said that in an independent Scotland the Queen remain as monarch  in the same way as she is in Canada, Australia and a host of other Commonwealth nations, McGarry is more radical.

Asked if she loved the Queen she retorts: "No!".

She adds: "I am sure there's nothing wrong with the Queen herself, right, she's a wee old woman, when she takes off her hat, she's about four foot ten.

"She has worked hard all her life, she's been very well recompensed.

"Do I think there should be a royal family? Absolutely not.

"Should they be draining money out of society?  No."

The Herald:

The chat starts with heated analysis of the recent Chinese state banquet at Buckingham Palace where guests dined on fillet of West Coast turbot,  Balmoral venison and bottles of Chateau Haut-Brion 1989 which cost £1354 a throw.

President Xi Jinping and his wife Madame Peng Liyuan joined more than 170 guests including the Queen in the Palace ballroom for the sit down meal.

She expressed outrage at a time of austerity and planned tax credit cuts.

She said:  "It's absolutely disgusting that you have a situation where people are quaffing on a bottle of wine which is more than the  average than the tax credit cut per average family. 

"And the impact of that bottle of wine on that person's life compared to the cuts that will impact on the poorest people...it's disgusting. 

The Herald:

The Duke and Duchess of Cambridge also attended the dinner, with Kate Middleton wearing a red gown, the colour of the Chinese national flag, for her first State banquet at Buckingham Palace.

"Having been to China on numerous occasions, I can tell you the £1450 (cost of the wine) is a lot more than you'd pay for the Great Wall of China wine which seems perfectly sufficient in China," she said.

"Basically what it is is the British state trying to live up to this idea it's an empire. It's trying to compete and quite frankly it's got squashed."

The wide ranging discussion covering subjects such as Syria, fracking, working with Labour leader Jeremy Corbyn and David Cameron, Katie Hopkins and what it means to be British.

"There is this determination to ringfence this idea of British identity that  is not lacking. People feel how people feel. You can't ascribe sentiment to people," she said.

"It's a reaction to Scottish independence, referendum as we.... it's a very determined programme to try and control people.

"This is very much to tie people into a national identity so that people behave in a certain manner. And I think if you look  at it, it really started with the 2012 Olympics.  This rebranding of Team Britain, which went beyond the actual Olympic team. 

"This idea that we are all in it together, which isnt' true, because if we were all in it together, the people at the top wouldn't be shafting the people at the bottom. 

"It's trying to distract people from the reality that is within the British political structure, that's within British economic life, people at the bottom are being treated basically like animals. 

"Whilst in one sense they are trying to promote this unity, at the bottom they are trying to create disunity."

The performance artist's stunts had him in Glasgow 14 years ago when he protested against political corruption in Scotland dressed as a snake outside Glasgow City Chambers.
