Revealed: data from UK anti-radicalisation scheme Prevent being shared with ports and airports

Personal details from voluntary programme sent secretly without consent with government departments and border agencies, document shows

Details of thousands of individuals referred to the government's controversial anti-radicalisation Prevent programme are being shared far more widely than was previously known, with data secretly sent to airports, ports and immigration services, as well as officials at the Home Office and the Foreign, Commonwealth and Development Office (FCDO).

Critics believe the widespread sharing of data could be unlawful, with sensitive personal details of those referred to Prevent being moved between databases without the knowledge or consent of the individuals concerned.
