Glamour model Chloe Ayling will not give evidence at the trial of her alleged kidnapper, which is under way at an Italian court.
Lukasz Herba kidnapped Ms Ayling last July as part of a £250,000 ransom plot, the court in Milan was told.
It has been claimed that the 20-year-old from Croydon was drugged and held captive for six days before being released.
Mother-of-one Ms Ayling is thought to have been excused from testifying during Herba’s trial – but defence lawyers are planning to appeal the decision, Mail Online reported.
She did not appear in court as the trial got under way.
Herba, 30, denies kidnap, claiming that the entire incident was faked as a publicity stunt.
But Ms Ayling, who has 290,000 followers on Instagram, insists she was abducted but Herba later took pity on her when he learned she had a two-year-old son.
A number of police officers are reportedly due to give evidence in Herba’s trial.
Prosecutors claim Herba was part of a sex trafficking group called Black Death.
The organisation is said to operate on the dark web, but it is not clear if it has a significant influence, or if it even exists.
They will argue that Ms Ayling arrived in Milan for what she believed to be a modelling job, but was instead bundled into the boot of a car by Herba.
He was arrested on July 17 after handing Ms Ayling in to the British consulate in Milan.
Herba could be jailed for 30 years if he is found guilty.
