Phil Spector's lawyer has become embroiled in a row over a broken nail said to belong to the actress the record producer is accused of killing.

Mr Spector's attorney, Leslie Abramson, refused to hand over the purported evidence to prosecutors - and later said the nail does not exist.
A US judge has delayed a decision on whether to order the evidence to be handed over until 21 May.
Mr Spector is charged with murdering Lana Clarkson in February last year.
"We don't have a piece of nail. If I had a piece of nail I'd blow it up poster-sized and put it on every billboard in Los Angeles County. They don't want to hear it," Ms Abramson told reporters outside the court in Alhambra, California.
But she refused to say in open court if the nail existed.
District Attorney spokeswoman Sandi Gibbons said prosecutors were not willing to take the word of Abramson "standing out here on the sidewalk" but would wait for the hearing outcome.
The nail was allegedly overlooked at the crime scene and found by the defence team's investigators in January.
Mr Spector spoke only to tell the judge that he was willing to postpone again his preliminary hearing, which will determine if he must stand trial in the case.
The producer faces life in prison without parole if convicted.
Mr Spector made his name in the 1960s, when his Wall of Sound technique transformed pop music and he produced acts like the Beatles and the Ronettes.
