Informant On 2 January, Smalls asked for a meeting with the lead Inspector. In the conversation, Smalls (having been informed by his solicitor that he would be serving at least 25 years if convicted) offered the police a deal to name and incriminate those involved not only in the Barclays Bank job but in every piece of criminal activity he had ever been involved with or known of. An agreement was drawn up between Smalls and the Director of Public Prosecutions, Sir Norman Skelhorn, that gave Smalls immunity from prosecution in exchange for his help.
