Naomi Campbell testifies on Thursday about a "blood diamond" at the war crimes trial of former Liberian leader Charles Taylor, who prosecutors say gave such a gem to the British supermodel.
The prosecution at the Special Court for Sierra Leone summoned Campbell to back their allegations that Taylor received diamonds from rebels in Sierra Leone, which they say he then used to buy weapons during a 1997 trip to South Africa.
Defense lawyers for Taylor have sought to delay the testimony, arguing the ex-Liberian president's right to a fair trial is being denied because they have not seen the full intended statement by Campbell. The court was expected to rule later on Wednesday on the request.
Taylor -- accused of being given the diamonds by rebels a month before his trip to South Africa -- is said by prosecutors to have given Campbell a large rough cut diamond after a dinner hosted by Nelson Mandela. Taylor has said this is "nonsense."
"The timing of this dinner is important because if this story ... is true, it places Taylor in possession of at least one rough-cut diamond the month after the rebels came to see him, and the month before the junta received a large shipment of weapons in October," said Open Society Justice Initiative, a human rights organization monitoring the Taylor trial.
Campbell's testimony has sparked intense media publicity, with more than 200 journalists hoping to attend. But Campbell, an unwilling participant, won a court ruling banning photos of her entering or exiting the court on concerns over her security.
She will still be filmed while giving testimony, however.
On trial in The Hague, Taylor denies all 11 charges of instigating murder, rape, mutilation, sexual slavery and conscription of child soldiers during wars in Liberia and Sierra Leone in which more than 250,000 people were killed.
One of Campbell's London-based lawyers, Gideon Benaim, declined to comment. "Ms. Campbell will give her testimony in the Hague on Thursday," he said.
Mia Farrow will be calledProsecutors have said Campbell is in a position to provide material evidence and will also call modeling agent Carole White and U.S. actress Mia Farrow to the stand on Monday.
The prosecution said White heard Taylor say he was going to give Campbell a diamond and was there when Campbell received it, while Farrow attended the reception where Campbell met Taylor and was told later by Campbell about the gift.
The court has granted one of Campbell's lawyers a limited right to intervene on whether to allow questions for Campbell if she could incriminate herself by answering them.
"Direct examination will be very brief. The prosecution has no idea of the length of cross examination," prosecutor Brenda Hollis said. "Ms Campbell's testimony will provide the judges with another piece of the overall picture."
Taylor's lead Defense lawyer Courtenay Griffiths has argued, however, that Campbell's anticipated evidence is "entirely based on conjecture," stressing in court filings Campbell has denied publicly ever receiving a diamond or diamonds from Taylor.
Campbell had also expressed concern about her safety and initially refused to testify, prompting the court to subpoena her. A subpoena is a legal measure used to gain testimony from an unwilling witness on the threat of a fine or imprisonment.
