Thats a great idea but ultimately you cannot have different rules for some businesses than others. So if its legal for business in the UK to trade with a country then that means all businesses including football. Its not hard to understand. At the moment its even legal to trade with Iran ffs as long as not weapons.
Now having a trade policy that is based upon human rights I dont have a problem and that would mean it would be impossible to trade with many African regimes, China, Iran, most of the Middle East, many South East Asian countries. This would mean the bandits and human rights abusers would be kicked out football and Im happy with that, but unfortunately we don't have a government with balls, as they know doing that would wipe billions off the stock exchange. London property prices would collapse because of all the property Russia plows into it laundering their bent cash.
So until something happens stop trying to have a go at Newcastle who have done nothing wrong or illegal
