Nirav Modi moves new bail application, hearing on November 6

His legal team has previously also sighted the “severe” conditions in Wandsworth prison in London, one of England's most overcrowded jails, in their bail attempts.

The diamond merchant's troubled state of mind was laid out before in "confidential" documents before the UK High Court during his bail appeal earlier this year, which were not disclosed due to a court order.

“The circumstances he has had to endure at Wandsworth have been personally difficult and the confidential exhibits reflect the experience that has marked him deeply,” said his barrister Clare Montgomery, during a hearing at the Royal Courts of Justice in London in June.

“The reality is that he is not the cold-blooded hardened criminal as claimed by the government of India but a jewellery designer from a long line of diamond dealers, and regarded as being honest, careful and reliable,” she said, adding that a number of individuals were willing to offer sureties and substantial sums to back up the claim that Modi is not a man who plans to run.

But in her judgment, Justice Ingrid Simler had concluded there were “substantial grounds” to believe that Modi would fail to surrender as he does possess the means to “abscond”.

Reiterating similar concerns as those previously raised by Westminster Magistrates' Court during earlier bail attempts, Judge Simler ruled that after considering all the material “carefully”, she had found strong evidence to suggest there had been interference with witnesses and destruction of evidence in the case and concluded it can still occur.

However, there are no strict limits on the number of times Modi can apply for bail, and another application will now be heard next week. He was scheduled to appear via videolink from his jail for a regular remand hearing at Westminster Magistrates' Court on November 11, a date that still remains on the court's lists.

At a hearing earlier this month, Judge Nina Tempia had confirmed that his extradition trial is scheduled between May 11 and 15 next year and that he must re-appear via videolink every 28 days for “call-over hearings” until the case management for the trial kicks in from February next year.

Modi has been lodged at Wandsworth prison in south-west London since his arrest on March 19 on an extradition warrant executed by Scotland Yard on charges brought by the Indian government, being represented by the UK's Crown Prosecution Service (CPS) in court.

During subsequent hearings, Westminster Magistrates' Court was told that Modi was the "principal beneficiary" of the fraudulent issuance of letters of undertaking (LoUs) as part of a conspiracy to defraud PNB and then laundering the proceeds of crime.
