Ukraine official, Volodymyr Zelensky as the new president.

Election authorities in Ukraine have officially named TV star and comedian Volodymyr Zelensky as the new president.

The Central Election Commission on Tuesday presented the official results of the April 21 vote, showing Zelensky beat incumbent President Petro Poroshenko by winning 73 percent of the vote.

Zelensky has criticized election authorities for dragging their feet on naming him the official winner, which reduces his chances of disbanding the parliament, AP said.

Zelensky will only be able to call an early election in parliament, which is currently dominated by the allies of the outgoing president, if he is sworn in before May 27. The parliament now has a month to set the date for the inauguration ceremony.
