I’m sorry, I know a lot of people slate Boris off on here, but he does not need to do this as his term is coming to an end, but has and absolute kudos to him for doing it, especially as on this day, the Ukrainian Independence Day when the threat from Russia was particularly high and parades had deliberately been cancelled.
Say what you like, but few leaders would do that and he is showing Ukraine we are still with them.
