Not a footie fan at all but I do know that he is Russian and v rich (obviously). But I dont know why he would hand over stewardship of Chelsea FC to the trustess (he still retain ownership as I understand it), unless it is simply because of a backlash over his nationality, or because he is supportive of the invasion.
Sorry if I sound thick, its because I am about football and wondered why him running the club is relevant to the Ukraine situation.
