The former Royal College of Music professor Jan Repko appeared in Westminster magistrates court on Saturday, charged with a single count of sexual assault by penetration. Repko, 64, failed to enter a plea.
He was released on £15,000 bail and is due to appear at Southwark Crown Court on March 17.
The charge relates to a woman over the age of 16.
Repko was dismissed in December from his teaching posts at the Royal College of Music and at Chetham’s school in Manchester after the allegations came to light.
