This is the shocking moment that a guest invited to speak to a council meeting ended up in a toe-to-toe fistfight with a politician.
Boris Lebedtsov, a senior manager at a hotel in the city of Cherkasy, in central Ukraine's Cherkasy Oblast region, had been invited to speak at a meeting of the Cherkasy Regional Council.
But Mr Lebedtsov, the acting director of the local Dnipro Hotel Complex, angered politicians when he insisted on speaking in Russian.
Members of the nationalist Svoboda (Freedom) party demanded that he speak in Ukrainian but Mr Lededtsov insisted that it was a lot easier for him to speak in Russian and carried on.
Yuri Botnar, a deputy for Svobada, then approached the podium with his fists raised and started swinging punches at Mr Lededtsov.
The hotel director stood his ground as other politicians looked on until they were separated by security guards.
After the fight, Mr Botnar said that his party would not allow any more speeches to be made to the regional council in Russian.
The punch-up was caught on camera and the footage quickly went viral after it was posted on video-sharing websites.
Netizen 'Matey Podzhigay' commented: "It is important to suppress laughter while we watch how Ukraine goes down in pieces."
And 'Nikita Utkin' added: "Wilderness. Soon they will start fighting for a banana."
Tensions between Ukraine and Russia have been on a knife edge for several years now.
In 2014, Russia made several military incursions into Ukraine after the Euromaidan protests and the fall of Ukrainian president Viktor Yanukovych.
First Russia annexed the Crimean peninsula, then demonstrations by pro-Russian groups in the Donbass area of Ukraine escalated into an armed conflict.
