Members of Ukrainian opposition groups on Monday pushed to pass a vote for a return to the 2004 constitution which would give less power to the president.
But the bill was blocked by parliamentary staff who refused to register it on procedural grounds, causing the situation on the streets of Kyiv to intensify.
Opposition leader Arseniy Yatsenyuk claimed President Yanukovytch personally ordered the bill to be blocked.
“I think that if the text was presented to the floor, it could have obtained the support of the majority. Because people clearly understand we were robbed of our Constitution,” he said.
“The fact that the parliament is blocked from voting on this bill, is only because President Yanukovych didn’t give a green light to a full voting procedure and finally start a real dialogue in Ukraine,” continued Yatsenyuk.
Opposition members accuse Yanukovich of delaying discussion that could lead to reducing what they call his “dictatorial” powers.
Yanukovitch plans to meet with opposition leaders on Wednesday and a debate is expected to take place on Thursday.
