Decca Music Group has confirmed a "realignment" of its U.K. operation, with part of its roster transferring to Universal Classics & Jazz.

"Decca's classical crossover and other signings will be assigned to UCJ, the U.K.'s longstanding No. 1 classical labels," said a Decca statement issued to by Universal Music Group International. "Decca Label Group in the U.S. is unaffected by this realignment."

The statement reaffirmed Decca's position as an "active" label in the U.K., which will continue "signing and recording artists." The label will continue to operate its London office as a "creative centre."

According to Universal Music Group, UCJ claimed 55% of the U.K. classical market in 2008 and possessed seven of the top 10 classical albums.

Last month Bogdan Roscic quit as the London-based managing director of the Decca Music Group, moving to become president of Sony Music Classical.

Decca Music Group's roster includes Luciano Pavarotti, José Carreras and Renée Fleming.
