The soprano wants more money for her compilation A Soprano in Love, a double CD album with 34 tracks.

The 43-year-old singer has issued a writ against Silva Screen Records.

It alleges that the independent label should pay her more royalties for the album because it was advertised on television.

Silva Screen Records has said it will defend the claim and expects the case to go to the High Court.

"We had a good relationship with Lesley Garrett during her time with us and we are sorry it has come to this," said spokeswoman Amber Ross.

Cross-over artist

Miss Garrett left Silva Screen records last year.

She is one of the few sopranos who has successfully bridged the gap from stage to recording artist.

She has established herself as non-traditional operatic performer, with her records often crossing over into the pop market.

She was one of the many stars featured on the single Perfect Day, the remake of the classic Lou Reed song released by the BBC last year.
