Ukrainian Minister of culture Tkachenko wants to appeal against the decision to move the musical contest "Eurovision-2023" from Ukraine to the UK.
"Holding the Eurovision Song Contest - 2023 in Ukraine is a strong signal to the world that it supports Ukraine now,” - he said
I'm not convinced that politicising it will help. I get the impression that the decision was made for safety reasons and in view of the uncertainty for an event that takes 11 months to plan.
Its likely there will be heavy Ukrainian involvement but i just can't see them hosting it.
