Current research

An exploratory investigation of the implementation of Stalking Protection Orders in England and Wales

This study explores the use of Stalking Protection Orders (SPOs) in tackling and preventing stalking in England and Wales. The project investigates: what types of stalking are being addressed by SPOs; how SPOs are being used by the police, the CPS and HMCTS; differences in approach among forces, challenges and best practice. This project is one of the first to analyse quantitative data on SPOs from Freedom of Information requests to all police forces in England and Wales, the CPS and HMCTS. In-depth insights into implementation, challenges and best practice are drawn from interviews with practitioners working with stalking including police, stalking charities, NGOs, the CPS and HMCTS.
