Chief Constable Mike Cunningham, CEO at the College of Policing, said: “The role of the police in any investigation is to secure and preserve evidence.
"We want to ensure officers and staff are supported to make the improvements being set out today and have access to the best available learning for disclosure. To date we have produced detailed disclosure learning standards, guidance and training tools for forces to implement locally, but this is just one part of the solution.
"We must be sure the criminal justice system works together to achieve sustained improvements to disclosure practice. This will involve cultural change and strong leadership to influence the mind-sets of officers and staff responsible for meeting disclosure requirements. We will support leaders and champions in forces and across the criminal justice service to achieve this."
