Innocent until proven guilty in every civilized country. The reality is he was not working for RT. Even if he was, that does not have "consequences". That is perfectly legal. The UK needs laws like the ones Florida and Texas have passed which prevent banks from de-banking businesses for non commercial reasons....and this needs to be extended to individuals. If the banks are found to be violating this, simply pull their charters.
Did you not read that he was offered a bank account, he was just denied the privilege daccount that he thought he was due.
