An inquest into the death a year ago of an IT analyst who worked for Abbey National begins today.
Richard Chang fell from a fifth-floor balcony at the financial firm's headquarters in London.
According to the Financial Times, solicitors for Chang's parents said that they are hoping for an open verdict or one of unlawful killing.
The solicitors have alleged that there was an abuse of employment law in the way Abbey carried out an investigation into the origins of an anonymous document sent to senior executives at the bank earlier last year.
The document contained allegations of financial and sexual impropriety regarding bank contracts awarded to third parties, which were later found to be groundless.
Chang fell to his death after being interviewed by Kroll, a firm of private investigators called in by Abbey to find out who had sent the document.
Chang had been due to leave Abbey for a new job.
