Yuriy Lutsenko, the leader of the Petro Poroshenko Bloc at the Ukrainian Verkhovna Rada, believes the leaders of the parliamentary factions should start negotiations on putting together a new coalition as early as next week.

"The leaders of the democratic parliamentary factions should start negotiations on setting up a new coalition for a new government next week," Lutsenko said on his Facebook account.

The denial of the fact of the coalition's breakup can only worsen the political crisis in the country, he said.

"The prime minister's unwillingness to recognize [the coalition's breakup] leads to the broadening of the crisis of confidence not only between the government and the Ukrainian people but also between Ukraine and its Western partners. We are losing visa-free travel, cooperation with the IMF, and a lot of other things," he said.

Lutsenko said he proposed that, immediately upon returning from Brussels, the faction leaders sit at a round table and reach agreement "on resuming the coalition's work."

"Having sat at the negotiating table, the leaders should start with objectives, not with names. What is most important is the calendar plan of reforms. After all, reforms are not only the prime minister's and the government's job. Reforms also depend on the parliament's voting. Therefore, these are inseparable parts of the same mechanism," the Petro Poroshenko Bloc party press service quoted Lutsenko as saying.

The Petro Poroshenko Bloc has drawn up a monthly plan indicating what the parliament should vote for and what the government should do to promote reforms stipulated by the coalition agreement, he said.

Lutsenko denied that a decision was made on Prime Minister Arseniy Yatseniuk's dismissal. "As a man who regularly attends conferences hosted by the president, the prime minister, and other officials, I'll say that no decisions were made on Yatseniuk's dismissal at these conferences," he said.

Lutsenko pointed out that it is not for the president to decide on a prime minister's dismissal but that this is exclusively the parliament's function, and the parliament should gather, admit the existence of a crisis, develop a plan of actions before the end of the year and then decide who can fulfill this plan.

"In my view, this calls for modifying the entire government, but this needs to be agreed upon between all factions making up the coalition. And this work needs to be done next week, because we have no right to waste time," Lutsenko said.
