The Royal Philharmonic Orchestra (RPO) announced the appointment of the 42-year-old Russian on its website.

Petrenko said: "I'm passionate about Liverpool, one of the greatest cities anywhere in the world. We've achieved so much and I'm looking forward very much to the next three years working together as one of the world's great orchestras and the pride of Liverpool."

He noted "By 2021, my family and I will have enjoyed 15 amazing years here and I'm proud to be one of the longest-serving conductors in the Orchestra's long and distinguished history. Now the time feels right for me to take on new challenges.
