The low-profile contest was won tonight by the Ukrainian baritone Andrei Kymach, 31.
The prize is worth £20,000 and a peck on the cheek from Dame Kiri te Kanawa.
A graduate of the Bolshoi’s young artist programme in Moscow, Kymach debuted last year at the Liceu in Barcelona in I puritani. In January and February this year, he sang Don Giovanni in Nice and Antibes.
UK mezzo Katie Bray won the audience prize.
