The public inquiry into undercover policing in England and Wales was launched by the Home Office in 2015. The public inquiry investigates the police infiltration of hundreds of political campaign groups since 1968, with evidence provided by police officers and by activists who were targeted. SECP member Raphael Schlembach draws upon his own research into the public inquiry to offer written commentary on the delays and secrecy clouding the inquiry in a range of media, including the British Society of Criminology and The Conversation.
