It comes after Russia was barred from taking part in this year’s edition of the contest, which will take place in the northern Italian city of Turin from May 10 to 14.

Ukraine will be represented by folk-rap group Kalush Orchestra, which replaced Ukraine’s original act, Alina Pash, after a row over her 2015 visit to Crimea.

The band members are rehearsing separately amid the conflict in Ukraine, as they help out on the frontline by supplying food and medicine and assisting refugees to flee war-torn towns.

They plan to meet soon in Lviv to practise their entry, Stefania, which they said had become an anthem for Ukrainians during the war.

Ukraine won Eurovision in 2016, when Crimean Tatar Susana Jamaladinova of Ukraine, known as Jamala, triumphed with a song about former Soviet leader Joseph Stalin’s deportation of hundreds of thousands of people from her Black Sea homeland, two years after Russia annexed the territory.

The following year, host Ukraine barred Russia from taking part.
