They might both serve as Aberdeen councillors.
But there has been no sign of an entente cordiale after a Brexit battle erupted between two Torry and Ferryhill councillors.
Conservative Alan Donnelly said in a committee meeting this week that he did not feel that a potential £65 fee for EU nationals to stay in the UK after Brexit was “excessive”.
But SNP member Christian Allard, who is originally from France, has vowed never to pay the money, arguing that he has lived in Scotland for more than 30 years.
Applications will cost £65 for adults and £32.50 for children and be free for EU nationals who already have residency or indefinite leave to remain.
Mr Allard said: “”I simply won’t pay, register or apply for the basic right to live in my own home amongst my family and friends of more than 35 years.
“Moreover, there is absolutely no certainty that applications will be accepted and, given the hostile environment created by the Prime Minister, I’m not alone in fearing that it could be refused.
“Mr Donnelly’s ignorance on this subject is breathtaking, but not unsurprising given the hostile approach his party has taken towards immigrants, coupled with their incessant desire to throw Aberdeen off the Brexit cliff.
However, Mr Donnelly responded by accusing his rival of “scaremongering”.
He said: “People have to answer three questions and pay a fee. I don’t think that is excessive.
“People pay £80 for a passport all the time, some countries charge for both tourist and business visas and I paid £80 for a Russian visa in 1999.
“The SNP only want to use Brexit to create grievance and division.
“If he wants to break the law, then he can face the consequences of that after Brexit.”
