Tony Goode, the Marks & Spencer whistleblower who was fired after revealing details of the company's plans to reduce its redundancy benefits, has said staff are subject to a culture of fear and surveillance at the high street giant.
 
Goode, who spent more than 20 years working with the company, claimed M&S routinely monitored its employees' behaviour in a press conference at the Trade Union Congress in Brighton.
 
Goode said M&S had provided reporters with details of his personal phone calls, conducted on his mobile phone.
 
M&S dismissed claims it had monitored his personal calls as "utter nonsense" and said his criticism represented "the lone voice of a disgruntled former employee".
 
Goode is being represented by the GMB union as it attempts to overturn his dismissal on appeal. The case could reach an employment tribunal if no settlement is made.
