Lol! Sending condolence messages are included in the protocol of the world leaders and that's why we have seen such things. It didn't effect the world activities in any way whatsoever. It could have an impact in UK itself but nowhere else! Kenya is not the world!
Every country in the world is facing a great challenge called recession. UK is a democratic country and the king and queen literally had no control on the policies of UK. They have a parliamentary committee to take care of the country. The King is a honorary post and it will remain that way. Financial challenges are different and there's no impact from Queen's death!
