"I don't understand our government, which only throws up its hands and tells me that we can't do anything".
"The country needs changes and fundamental reforms", the president-elect's team said in a statement on Friday.
In a sign of possible tensions between Kiev and Washington, Ukraine's key ally against Moscow, US President Donald Trump's personal lawyer Rudy Giuliani this month cancelled a visit to Kiev, saying Zelensky is 'surrounded by people who are enemies of the (US) president'. "I am ready to lose my popularity, my ratings if needed, or even my post as long as we achieve peace".
The political situation prompted one pro-Western lawmaker, Serguiy Vysotsky, to warn Zelensky that the inauguration "isn't the end of your adventures - it's just the beginning". Instead, he told them to hang photos of their children and look at them before taking decisions.
President of Ukraine Volodymyr Zelensky has announced that he dissolves the Verkhovna Rada of Ukraine of the eighth convocation. "Do it and you will deserve medals", Zelenskiy said after being sworn in.
Zelenskiy announced in his inaugural address that he was disbanding the Rada, Ukraine's unicameral parliament, and the consultations are part of the process.
Zelensky also called for the sacking of the head of the state security service, prosecutor-general and defence minister who are loyal to his predecessor but these moves have to be approved by Parliament.
Critics say he has given few specific details about his plans for the presidency and have questioned his links to Ihor Kolomoisky, a billionaire oligarch who had fallen out with the previous government.

Speaking on television after his appointment, Bohdan said that a possible peace deal with Russian Federation must be put to a referendum. Russian Federation has condemned that law as a provocation and on Monday called an emergency session of United Nations Security Council to discuss it.
Many lawmakers had already viewed Zelenskiy's inauguration with apprehension, and it was not clear if the new president could legally dissolve the sitting parliament.
Although the legal status of Zelensky's move to dissolve Parliament remains uncertain, he claimed on Tuesday that he has the authority to disband the legislature because "since 2016, there has been no coalition". The move, pushed forward by the opposition party People's Front, was widely seen as a political maneuver to stop Zelenskiy from calling early elections.

A professional comedian was yesterday sworn in as president of Ukraine but if he isn't careful it may be Vladimir Putin who gets the last laugh. 'In my life, I've tried to do all I could to make Ukrainians smile, ' he said.
