EN43

EN43 is the cipher given to a former undercover officer of the National Public Order Intelligence Unit who was deployed in the late 2000s against unknown targets. Since leaving the NPOIU they remain a police officer working undercover for other operations. Sir John Mitting, chair of the Undercover Policing Inquiry, has ruled that the Inquiry will restrict the officers real and cover name in the Inquiry.Sir John Mitting, Applications for restriction orders in respect of the real and cover names of officers of the National Public Order Intelligence Unit and its predecessor/successor units 'Minded to' Note, Undercover Policing Inquiry, 2 May 2018.Sir John Mitting, Applications for restriction orders in respect of the real and cover names of officers of the National Public Order Intelligence Unit and its predecessor/successor units Ruling 1 and 'Minded to' 2, Undercover Policing Inquiry, 30 October 2018.

==As a police officer==
For many years prior to joining the NPOIU EN43 had been a Test Purchasing Officer, for which they give evidence in court proceedings under pseudonyms. They also completed the advanced undercover training course, following which they were deployed on operations targeting serious and organised crime.Gisted Witness Statement of EN43, original statement made 3 May 2017; gisted version released by Undercover Policing Inquiry 9 July 2018. Of this time:EN43 - Gisted summary of grounds of application, Metropolitan Police Service, undated, gisted version released by Undercover Policing Inquiry 9 July 2018.
:: The operations in which EN43 was deployed prior to secondment to the National Public Order Intelligence Unit involved serious criminals and crimes. A considerable number of the criminals have had access to firearms. In cases where there have been arrests and convictions there may be continuing hostility towards EN43 such that disclosure of his/her real identity might put EN43 at risk. 
Seconded to the NPOIU as an undercover officer in the last years of that unit's existence (it closed 2011). For this, they constructed a new pseudonym, and believes the individuals encountered on this deployment had have the capacity for 'serious violence' which would place him in serious danger of harm if his identity was disclosed.
After being with the NPOIU they continued to do 'dangerous covert work' and was employed in such a role in 2017.

* 2 May 2018: Mitting minded to restrict real and cover names,Steven Gray, Counsel to the Inquiry's Explanatory Note to accompany the Chairman's 'Minded To' Note 12 in respect of applications for restrictions over the real and cover name of officers of the National Public Order Intelligence Unit and its predecessor/successor units, Undercover Policing Inquiry, 2 May 2018. writing:Sir John Mitting, Applications for restriction orders in respect of the real and cover names of officers of the National Public Order Intelligence Unit and its predecessor/successor units 'Minded to' Note, Undercover Policing Inquiry, 2 May 2018.
:: EN43 was seconded to the National Public Order Intelligence Unit in the last years of its existence. Before and after that time EN43 was deployed by different police bodies in both criminal and non-criminal fields and is still employed by a provincial police force in a covert role. Some of the deployments have exposed EN43 to danger. Publication of the real name would create some risk to the safety of EN43. Publication of the cover name adopted by EN43 during EN43's secondment to the National Public Order Intell igence Unit would impair performance of current and future duties in the undercover field and may also put safety at risk. It would not be in the public interest to publish either. Further, publication would interfere with an element of the right to respect for private and family life of EN43 - physical integrity -and would not be proportionate or justified...
