The comedian Volodimir Zelenski swept the elections and is the new president of Ukraine

Actor, comedian and without political experience: this is the profile of Volodimir Zelenski, who won a landslide victory in the Presidential election of Ukraine outgoing President, Petro Poroshenko, in a result that reflects voter mistrust before the power.

The 41-year-old comedian had the 73.2% of the votes in the second round of the presidential against 25.3% for the rival of the South, 53, according to the poll at the mouth of the urn at the exit of polling stations by the consortium "Exit Poll National", which brings together three institutes.

The victory of Zelenski would open a new chapter in the history of a country shaken by two major popular rebellions in two decades and divided by a five-year conflict with the separatists of the eastern region.

Ukraine is a country that depends on international aid and Russian energy, so the new president will have to negotiate with Russian leader Vladimir Putin and the International Monetary Fund (IMF).

The challenges in Ukraine, a former Soviet republic faced with a situation unprecedented since independence in 1991, are considerable. When he came to power, Poroshenko followed the annexation of the Crimean Peninsula from Russia and a war that left about 13,000 dead in five years in the east of the country.

Earlier, US Secretary of State Mike Pompeo convened candidates demonstrate "your support for Ukraine's sovereignty and territorial integrity" and reiterated Washington's commitment to "working with all Ukrainian citizens, no matter what."

Except the promise to maintain a pro-Western stance Zelenski's program is not clear, despite the fact that in recent days he has tried to strengthen his credibility with specialized advisers.

According to Anatoli Otisiuk of the House of Democracy's Analysis Center, favorable polls during the pre-election the "mistrust" felt by Ukrainians towards "veteran politicians" because of "permanent scandals of corruption, of certain reforms, of the degradation of the standard of living or poverty".

Poroshenko had to get the support of Western countries, the recovery of the army and avoid the bankruptcy of the country, one of the poorest of the continent. But no senior official has been found guilty of bribery and the conflict in the East seems to stagnate, with no sign of resolution.

Presenting himself as the only barrier against Putin's Russia, he has not stopped insisting on the risks envisioned for his country. "An inexperienced actor can not wage a war against the Russian aggressor," the president warned. Kiev and Western powers accuse Moscow of militarily supporting pro-Russian separatists who control part of eastern Ukraine.

Although the comedian is not intimidated and uses high-impact phrases, when he is portrayed as someone a "simple" in front of the "richest president" from the history of Ukraine. "I am convinced that we can break the system," had boasted Zelenski before the debate.
