Ukrainian President Petro Poroshenko's proposal that Russia be deprived of a veto right in the UN Security Council is legally ignorant and will have no consequences, says Russian Federation Council international affairs committee head Konstantin Kosachyov.

"This initiative certainly cannot have any continuation by definition, as it reveals the lack of understanding of how the United Nations Organization is arranged and an elementary lack of knowledge of the organization's charter," Kosachyov told Interfax on Friday.

The veto right is a universal instrument that can be used without any exceptions, he said.

"This is precisely why this veto right instrument is efficient, strong, and is among the most powerful instruments preserving the United Nations Organization's capability. The introduction of any exceptions in this law would absolutely certainly destroy not only the veto instrument but also the UN Security Council structure, in which the five permanent members bear special responsibility for the organization's activity and ultimately for the world's fate," he said.

"Therefore, this initiative is ignorant from the viewpoint of international law and is destructive from the political viewpoint, because it poses a direct threat to the UN's capability," he said.

Ukrainian President Petro Poroshenko had proposed earlier that a discussion be started during the upcoming session of the UN General Assembly on depriving Russia of its veto right in the UN Security Council.
