Question to the Home Office:

To ask the Secretary of State for the Home Department, how many police officers have undertaken fire arms training in every year since 2010.

The Home Office does not centrally hold the number of police officers that have undertaken firearms training.
The Home Office does publish the number of officers in England and Wales that have passed firearms training and are authorised to use firearms – “armed officers”.
The latest release of “Police use of firearms statistics, England and Wales”, which includes the number of armed officers for the financial years ending March 2009 to March 2017, can be accessed here:
https://www.gov.uk/government/statistics/police-use-of-firearms-statistics-england-and-wales-april-2016-to-march-2017
The latest figures on armed officers, for the financial year ending March 2018, are due for publication in summer 2018.
