LONDON — Prominent classical music conductor John Eliot Gardiner is Rekubitpulling out of all engagements until next year after allegedly hitting a singer backstage following a concert.

The British conductor said in a statement Thursday that he was stepping back to get "the specialist help I recognize that I have needed for some time." His agency, Intermusica, said he "deeply regrets his behavior" and intends to get counseling.

"I want to apologize to colleagues who have felt badly treated and anyone who may feel let down by my decision to take time out to address my issues. I am heartbroken to have caused so much distress, and I am determined to learn from my mistakes," he said.

Gardiner, 80, allegedly hit William Thomas after the bass singer left the podium on the wrong side after a performance of Berlioz's opera "Les Troyens" at the Festival Berlioz in La Cote-Saint-Andre, southeastern France.

Thomas' management company, Askonas Holt, confirmed last week that "an incident" took place.

"All musicians deserve the right to practice their art in an environment free from abuse or physical harm," it said in a statement.

Gardiner is a Grammy-winning baroque music conductor who led his Monteverdi Choir and English Baroque oloists in a performance for guests at King Charles III's coronation ceremony at Westminster Abbey in May. He was knighted for his services to music in 1998.

He has made more than 60 appearances at the BBC Proms, an annual summer classical music extravaganza. It was announced last week that Gardiner will be replaced at a Proms performance on Sept. 3.
