Re: What possible delay?
I an fairly confident I can find incontrovertible evidence of Donald Tusk and President Obama actively intervening in the referendum.
Can you provide evidence that Putin actually intervened during the referendum? During the referendum, note: expressing an opinion after the referendum had no effect on the vote, so does not constitute interference.
Or are you just repeating lies? Allocations made by people that want to overthrow a democratic decision do not constitute evidence.
