May 15 2022
We're not talking about cheating at this point, but a serious setback. The Romanian jury's vote in favor of Moldova was "replaced" on Saturday at Eurovision by a "substitute calculated in a non-transparent way," Romanian public television TVR said Sunday. "We were unpleasantly surprised to see that the vote was not taken into account in the final ranking, with the organizers assigning another set of scores to the competitors in the final," TVR wrote in a statement. "We clarify that the Romanian jury decided to award the maximum score to the representatives of Moldova," it detailed.
On Saturday night, the twelve points of this country went not to Moldova but to Ukraine, which won the competition. Romania also regretted that "the rules were changed during the game", its presenter was not "allowed" to intervene live as the majority of other countries to communicate the vote of the jury of his country. Depending on the response it receives from the European Broadcasting Union (EBU), the organizing body of Eurovision, it reserves the right "to take measures to correct the situation.
Irregular voting patterns identified in six countries
At Eurovision, jurors from each country distribute points to the different countries and viewers vote by phone. On Saturday night, the EBU pointed out "certain irregular voting patterns identified in the results of six countries" in the second semi-final and the final.
It did not specify which states were affected or whether these irregularities could have an impact on the final ranking. "The EBU takes any alleged attempt to manipulate the voting at the Eurovision Song Contest very seriously," it said in a statement. Ukraine won the contest in Italy ahead of the United Kingdom and Spain, thanks to the vote of viewers who voted for the group representing the country invaded by Russian troops.
On Sunday, Ukrainian Culture Minister Oleksandr Tkachenko regretted that the Kiev jury did not award any points to Poland and Lithuania, two important supporters against Moscow. "Such an assessment does not reflect our true attitude towards you, our closest friends in Europe. It is a real shame to give Poland and Lithuania 0 points. Ukrainians give you 12 points!" he assured on Facebook.
